There are several types of computer errors that can occur at different stages of booting up or using a computer. These include hardware errors like no video output, software errors from corrupted files, and operating system errors. To diagnose issues, one should check connections, review error messages, update drivers, scan for malware, and test in safe mode. Common solutions involve reseating or replacing hardware, updating software, and ensuring proper ventilation and power supply.

Hope You will enjoy it.
Maintenance Planning and Scheduling are key elements that influence the true success of any organization. Many times we have a planner or planner/scheduler, but do not know how to use him or her effectively or efficiently.
Explains what troubleshooting is, what skills are involved, and clears up some common misconceptions. Originally designed with IT Helpdesks in mind, but it could apply to any kind of troubleshooting.
=========================
Wrote this a VERY long time ago! I always meant to revisit/revamp it, but never quite got round to it. But people seem to get value from it, so I'll leave it up :)
Any abnormality in the integrated components of a computer can prove harmful to its performance, but some general computer issues can be addressed without seeking professional IT help. Among the most common problems you may encounter are issues with the computer freezing and appearances of the infamous "no boot" or "blue screen of death." To repair a computer, you'll need to troubleshoot the issue and determine if the fix is something you can perform yourself; for more complicated problems, however, consider seeking the help of a professional.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Types of computer system error
1. TYPES OF COMPUTER SYSTEM
ERROR
COMPUTER HARDWARE AND SERVICING
LESSON 2, MODULE 4
MA. RACHEL B. ESPINO
Teacher, TLE-CHS
Buhatan National High School
2. • There are several errors in a computer from the
point you open it up to the point you reach the
stand by window (reaching standby windows
means boot process has no error). Here's a list of
computer error.
3. 1. No Video Output - When you open your PC,
nothing shows up in your monitor and the LED
indicator of your monitor is flashing in yellow
color.
4. 2. No Video Output - Same as number one but
now the LED indicator of your monitor is in steady
orange color.
5. 3. Doesn't Boot - When you open your PC it will
show the processor brand and/or the
motherboard brand but doesn't continue. Usually
this error will result to system restart over and
over again.
6. 4. Never Ending Loading of Operating System -
The computer opens up then boots but when the
operating system loads it doesn't continue and it
will take a lifetime if you're going to wait for it to
load.
7. 5. Lots of pop up windows showing on standby
mode - This also happens even if you try
disconnecting your computer set from the
internet. This is what we called aftershock virus
which will continue to run even if internet is
disconnected.
8. 6. Lots of hardware installation windows appear
- This happens even if you try installing the
hardware. When you restart your set it will
happen again.
9. 7. Safe mode doesn't work - When you try going
to safe mode all you will see is a list of files in
Command prompt style.
10. 8. Keyboard and mouse system restart - This will
happen only in standby mode, when you move
your mouse or type something, your system will
automatically restart and the worst part is it will
delete a file at random.
11. 9. Sound on/off error - Upon loading the
operating system, you will hear a loading sound
and then the sound stops, when you try running
an audio file, no sound will be heard.
12. 10. Application causes system to restart - Just
like the mouse problem, when you open a
program that will take the whole screen like for
example a game and/or a program applications,
after you close it, it will cause your system to
restart.
13. Operating System Errors
• Aside from the common computer errors,
computers also can have different Operating
System (OS) errors. OS errors can be classified
into various categories, such as:
14. 1. System errors – These are moderately
dangerous types of errors among those that can
pop up on your PC. System errors are caused by
malfunctioning hardware components, corrupted
operating system modules, etc.
15. 2. Runtime errors – Runtime errors are caused by
corrupted or malfunctioning system files or
software executables. Most runtime errors cause
the application that caused it to shut down.
However, more serious runtime errors may cause
the system to become unstable or unresponsive,
leaving you with no choice but to reach for the
Reset button.
16. 3. Stop errors – Stop errors are caused by
corrupted hardware, especially malfunctioning
RAM modules and bad sectors on hard disks. Stop
errors can be difficult to resolve at times.
17. 4. Device Manager Errors – These are usually
caused by corrupted driver files or malfunctioning
hardware components. In case of the former
cause, the problem is usually solved simply by
reinstalling or updating the drivers. However, the
latter cause can often be solved only by replacing
hardware components.
18. 5. POST code errors – POST code errors are
caused by malfunctioning hardware components,
and are characterized by short beep sounds from
the tiny internal speaker of your motherboard.
POST code errors occur when you press the power
button to turn on your PC..
19. 6. Application errors – These can be caused at
any point of time. As the name suggests, these
are caused by applications while those are
running. These are usually caused by glitches in
the program code itself. These are usually
resolved by updating the program to its latest
version.
20. 7. Browser Status Codes – These are caused by
problems faced by browsers when trying to access
a website. These can be caused by misplaced web
pages in the server of the website itself, or due
to connection problems. For instance, a 404 error
would indicate that the browser is trying to
access a webpage that does not exist in the
specified location.
21.
22. PC Diagnosing
• Probably the most frustrating problem computer
users run into are startup problems, where your
computer won’t boot. Equally annoying are error
messages you constantly run into during your
computer’s startup process. In this module you
will be given a few tips on how you can avoid
some of the most common problems that
happen right after your computer is turned on.
• Here you will learn the basic troubleshooting.
23. Trial and error:
• When you find a faulty component in your
computer, check it with the other computers so
that you can make sure whether the fault is in
the component or not.
24. Check cables:
• In case of any device failure, check all the cables
of your computer such as data cables, power
cable, internal circuitry cables and make sure
that all these are plugged in and working fine.
25. Hardware settings
• : Check the hardware settings in the CMOS and
in the device manager of the system and make
all the device drivers up to date and all the cards
are plugged in properly.
26. Notice changes:
• When you notice a software or hardware error in
your computer, determine what was changed
before the problem occurred.
27. Event viewer:
• In the event viewer, you will find the error or
warning messages associated with any faulty
hardware or software.
28. Make notes:
• Troubleshooting is a big learning option and we
can learn a lot when we face any kind of
troubleshooting in our computer. Make notes
including the error messages and their solutions,
so that you have a record on how a certain
problem occurred and how did you solve it.
29.
30. 1. Check the POST
• POST stands for Power On Self-Test. This is
generally the first or second thing that appears
on a computer after turning on the power. This
appears before the operating system begins to
load. The POST will display any problems found
with hardware that makes the computer unable
to boot, POST may also display problems with
hardware that allow the computer to boot, but
not operate at its full capacity during operation.
31. 2. Notice the load time of the OS
(operating system
• 2. Notice the load time of the OS (operating
system). A longer than usual load time may
indicate errors in the hard drive.
32. 3. Notice any graphics problems once
the OS has loaded
• Reduced graphics may indicate driver failures or
hardware failures with graphic cards.
33. 4. Perform an auditory test
• An auditory test is an unorthodox, but still effective way
of judging how a computer is working. With the
computer on and running, play any decent length audio
file (usually above 30 sec). If the audio is choppy or slow,
it usually means that the processor is working at an
elevated level, or there is not enough RAM to run all
programs loading. Changing the startup sound is a great
way to apply this test. Another issue associated with
choppy sounds is PIO (Programmed Input/Output)
Mode. This affects how the hard drive reads and writes
data from a drive. Switching to Direct Memory Access
(DMA) allows for faster reads and writes, and can
sometimes repair choppy audio.
34. 5. Check any newly installed hardware
• Many operating systems, especially Windows,
can conflict with new drivers. The driver may be
badly written, or it may conflict with another
process. Windows will usually notify you about
devices that are causing a problem, or have a
problem. To check this use the Device Manager,
this can be accessed by entering the Control
Panel, clicking the System icon, clicking the
Hardware tab, and clicking on Device
Manager. Use this to check and arrange the
properties of hardware.
35. 6. Check any newly installed software
• Software may require more resources than the
system can provide. Chances are that if a
problem begins after software starts, the
software is causing it. If the problem appears
directly upon startup, it may be caused by
software that starts automatically on boot.
36. 7. Check RAM and CPU consumption
• A common problem is a choppy or sluggish
system. If a system is choppy it is good practice
to see if a program is consuming more resources
than the computer can provide. An easy way to
check this is to use the Task Manager, right click
on the taskbar select Task Manager, and click
the Processes tab. The CPU column contains a
number that indicates the percentage of CPU the
process is consuming. The Memory Usage
column indicates how much memory a process is
consuming.
37. 8. Listen to the computer, if the hard
drive is scratching or making loud
noises, shut off the computer and have
a professional diagnose the hard drive
• Listen to the CPU fan, this comes on a high
speed when the CPU is working hard, and can
tell you when the computer is working beyond
its capacity.
38. 9. Run a virus and malware scan
• Performance problems can be caused by
malware on the computer. Running a virus scan
can unearth any problems. Use a commonly
updated virus scanner (such as Norton Antivirus
or Avast! Antivirus)
39. 10. Check for the problem in safe
mode
• To enter safe mode, tap F8 repeatedly during
POST (this works on most systems). If the
problem persists in safe mode, it is a fair bet that
the operating system itself is to blame.
40.
41. • 1. Double check the power connections.
• 2. Voltage Regulator and power supply could
• cause power failure in the computer unit.
• 3. Check the power cords and cable connectors
• in your computer unit.
• 4. Unseated card. Loose cards could cause
• malfunction.
• 5. Check the boot sequence configuration in the
advance BIOS (Basic Input /Output Unit) setup.
42.
43. • Things to look for if a PC is connected to the
internet or network:
• First check the cable connecting to the
network card into the network hub.
• Check the back of the computer to see if
the network card light is on
• Check the network cable ( use cable
tester)
• Check the network HUB
(use multi-tester)
44.
45.
46. IDENTIFY THE FOLLOWING ERRORS
1. Moderately dangerous types of errors among those that
can pop up on your PC.
2. Caused by malfunctioning hardware components, and are
characterized by short beep sounds from the tiny internal
speaker of your motherboard.
3. Caused at any point of time. As the name suggests, these
are caused by applications while those are running.
4. Usually caused by corrupted driver files or malfunctioning
hardware components.
5. Caused by corrupted or malfunctioning system files or
software executables.
6. Caused by corrupted hardware, especially malfunctioning
RAM modules and bad sectors on hard disks.
7. Caused by problems faced by browsers when trying to
access a website.
