BSOD please help

[rtatts]

Im having problems with my gfs computer. Basically its blue screening randomly and ruguarly. I first thought it might be a RAM issue so i ran memtest over it and it showed no errors. I then tested the CPU using prime 95 on the test which doe s mainly CPU test and it run for hours with no errors either. I did a visuall check of the capacitors on the motherboard and non of them are bulging.

Im starting to suspect it needs possibly to have the recovery console. I ran windbg to read the mini-dump files but ech one is different. I have it say these different ones say probably caused by:
win32k.sys
ntoskrnl.exe
kmixer.sys
classpnp.sys
HTTP.sys

Can anybody help me please?

is this a new build ??? or has it been working fine and has suddenly started doingthis ???
if its has just started doing this have you updated any drivers lately ?

or has windows automatically installed updated drivers. sounds like a bad driver file at the min

Its a previous system. I dont believe any of her family would know how to update drivers on there. All they knew was it was restarting randomly thats it. Could well be a faulty driver but i cant understand why when using debuging tool to read the BSOD each time it was different cause.
