Played game - crash - reboot ; failed - safe mode crashes - boot fails

Back home.
I can't run Furmark with the 64mb card, it gives an error saying it requires an OpenGL 2.0 compliant graphics controller. (Wow this card is really old...)
How do I run an OCCT power supply check?
It's running the Prime95 blend test as I type this. Will post results soon.

EDIT:
21:08; Test Started
21:25; Self-Test 640K passed!
It's already further than it got with the suspect GTX. But I'll let it continue testing for a while anyway.
Edit 2:
21:41; Self-Test 8K passed!
Continueing testing...
Edit 3:
21:57; Self-Test 720K passed!
Stopped it and going to run 'In-place large FFT's' test since it says it tests power consumption, so I guess this is the PSU test.
21:59; Test Started

Download OCCT and run their power supply test, it is one of the tabs on the left. Just click the tab and hit go.

Ok, downloaded OCCT and running Power Supply test now. Will report results a.s.a.p.

It just made some sort of duck-like noise (WTF lol) and said 'CPU too hot!'. It didn't crash or anything though. It opened a folder of graphs, I've zipped them up and attached them.
What's the next step? Or can a conclusion now be drawn?

I hope you were not running both tests at once! Make sure you run just the OCCT power supply test (go ahead and do it again) and let me know what happens.

Nah I wasn't running both tests at once, I stopped and closed Prime95, then started the OCCT power supply test, and that's what happened. It closed after saying it was too hot.

Ah, this is making sense now. It sounds like your CPU might be overheating, which would cause the crashes.
Run Prime95 again, and download RealTemp to watch your CPU temperatures. Let me know what they are idle and at load.

~Lordbob

Downloaded RealTemp, at Idle the temperatures hover between 27 and 29.
Now running Prime 95 In-place large FFT's test, soon as it started it jumped to 55, then started climbing. Still at Test 1 and already at 76 degrees now. As I type it went to Test 2, 79 degrees now. Is this normal? o.O

EDIT:
Selft-test 448K passed!
Top temp: 81 degrees
Continueing testing...
EDIT2:
All tests are passing and it isn't getting over 81 degrees.

That sounds like it got a little hot, but idle was good. You might consider getting a new heatsink.

I'll order a new CPU cooler set today, knowing the shop I usually purchase stuff from it'll be in my hands on wednesday by the latest, then I'll install it and put the GTX back in as well, then report back here. Hopefuly then the problems will be gone!
