Blue screen of death! Help me please.

Hi, try uninstalling the NVidia HD Audio driver, if installed.

I do not have that installed.  

Hi Steleten.

Depending on how much ram you have in the pc, its a good idea to pop your windows installation disk in and do a test of the memory, you should do at least three memory test passes to see if you get any errors. If you don`t then I would take a look at the Psu and ask if it feeding the pc with enough stable power.
If you can also check to see how hot your Cpu is getting could be getting a bit hot. And a nice little dust out of the case if it has never been opened for a few years and a good clean out of all the dust helps it breath a bit to keep things cool.

Do a scan of the Hd also making sure there are no errors on it, and perform a malware check, and a virus check.

Hey, thanks for the reply. I will ask my friend for a windows disk today and I'll try that. I just recently cleaned my computer because it was very dusty, the temperature is at about 55C with a game running.

Good luck Steleten.
I hope it helps and everything works ok.
