I used Heavyload to stress the CPU for 30 minutes, the CPU load was 80%-100%. The temprature as calculated by Everest stayed at around 49, 50 degrees throughout, there were no crashes.
Heavyload again, I allocated ALL of the ramspace that i have, until i had none left. There were no crashes.
I ran both the CPU and RAM tests simultaneously, and there were no crashes.
I downloaded and ran 'Video Stability test', by freestone group. After 5 minutes of running, the whole PC bombed out to black, and sat there.
I restarted the PC, now convinced that I had nailed the problem on the graphics card somewhow. I ran the test again, looking closely at the temprature. Strangely, it didnt go above 55 degrees centigrade, so it wasnt overheating, sure enough after about 5 minutes it crashed out to black again.
Applying logic here suggests that the GPU isnt actually malfunctioning because it DOES provide top notch graphics, and it DOESNT overheat. but for some reason, the whole system dies when you run some graphics for more than 6 minutes. The time isnt exact either, it varies, between 5 and 10 minutes sometimes.
I went back and retested the CPU watching the temp carefully for a whole, again there was no crash and the CPU temp didnt tise above 53 degrees.
I ran the GPU test and watched the CPU temp, again nothing above 53 degrees.
So nothing is overheating, the GPU runs fine for a while, then dies and it doesnt appear to be the RAM. what is going on here.
