mkhurram79, I do indeed like it.

I wish I had known about the meaning of the different beeps made by my computer some months ago.

Quite a number of us know more or less about errors in software but when it comes to hardware, it is my experience that we are clueless.

Regards

[mkhurram79]

infact i am not computer specialist. I can exchange only my observation.

-Small beeps with low noise indicates that your harddisk is going to expire soon.
-It might possible that keys of your keyboard are stiff. One key struck inside and when u press other key. System make a beep like noise.
-Some beeps are indication of low volatage
-some beeps are indication of virus attach.
-Some beeps are indication of non compatible operation via key board of mouse.

But i do not know exactly what happened with ur system. Plz contace any specialist.

Your system should have problem regarding the corrupt of one or more system file. Just go to My Computer and in the property tab in advance click and unmark the check box to the automatically restarts windows and just restart windows, if the problem is still as it is may be your system file kernal32.dll corrupt. just reinstall it.
