Hello TH Forum,

I need some help with an issue I am having.

I have had my PC for about a month now which I built myself. I have always kept the turbo for the CPU disabled in the bios. Up until today the computer has never crashed on me and I have ran several stress tests (prime95, Furmark CPU burn test) on it for an hour each time without issue, and the core temp never exceeding 50 degrees celcius.

Today I decided to turn the turbo mode ON in the bios and do a stress test, and also a windows 7 index experience assessment test. While doing that the computer froze so I had to keep hold of the power button to turn it off, after turning it on right away I disabled the turbo mode in the bios and tried to stress test again and the computer froze again.

Weird as the Windows 7 experience index subscore is different now to what it was before, it was giving me a score of 7.5 and 7.6 for processor and ram and now it's giving me a score of 7.7 for both (with turbo off).

Whilst doing the stress tests I had the monitoring programs CPU-Z and HWmonitor open, and easytune 6 was running in the background which I have now uninstalled because I thought it might be the cause of the problem.

When stress testing I kept an eye on the core temp and it didn't exceed 46 degrees celcius just before it froze, so overheating can't be the cause of the freezing.

My system specs...

AMD FX-8320 (stock) CPU
CM 212 evo cooler
Gigabyte 970a-ud3p Motherboard
Hyperx fury 2x4 8GB 1866 mhz RAM
Samsung Evo 250GB SSD
AMD r9 280 GPU
Antec hcg 620w PSU

Any help much appreciated

Thanks
