Customer has a faulty PC, she gave up on it when she took it back from a repair shop, and it immediately showed a blue screen of death (BSOD).
In disgust, she put it away in a cupboard, and purchased a new PC.
When the new PC started having some problems after a few months, she brought both PC to me for fixing.
I start the older PC, and it seems to start normally.
I then run a test to strain the video card and CPU, and within 2 minutes, I get the blue screen:
stop 0x000000EA, nv4_disp.dll, etc etc.
Well, it seems obvious: NV = NVidia = Video card fault
I remove the video card, activate the onboard Video (also NVidia!), and download the right drivers.
I then restart & run the test again… and this time it runs for over an hour without a problem.
Some video cards are just not made to last.
