BSOD randomly! Please help me, i have exams.

You have a few unnecessary programs in startup.

Free up the startup. Windows does not need any other program to auto start with it, but the auto start programs often conflicts and causes various problems including BSODs.

1. Click on the Start button
2. Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
3. Select the “Startup” tab.
4. Deselect all items other than the antivirus.
5. Apply > OK
6. Accept then restart.

Observe how the computer is running then.

Could I ask an idiot question - you mentioned at the beginning the BSOD came up when you unplugged the power lead. What happens if you leave the battery out?

I only ask because it seems to me every time you unplug something the machine goes south? and I am thinking maybe the battery is shot and causing problems like for example an over voltage or suchlike - just a hypothetical.
