There are several errors in a computer from the point you open it upto the point you reach the stand by window ( reaching standby windows means boot process has no error).
Here's a list of computer error.
If you experienced one of these error feel free to post you questions here and we will help you as soon as you provide the necessary information.


Common Computer Errors:

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.

2. No Video Output - Same as number one but now the LED indicator of your monitor is in steady orange color.

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.

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.

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.

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.

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.

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.

9. Sound on/off error - Upon loading he operating system, you will hear a loading sound and then the sound stops, when you try running a audio file, no sound will be heard.

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 proglang applications, when you close it, it will cause your system to restart.
