Random restarts with my new build.

Problem: Random restarts, no BSOD or freeze, system will immediately turn off then turn back on again. Happens multiple times at varying intervals, mainly while benchmarking and gaming.

What I tried: Ran memtest twice, showed OK, monitored temperature (70 CPU, 65 GPU), switched out power supply (Corsair CX 600 to TX 750), and updated GPU drivers.

My system:
- Gigabyte GA-B75M-D3H Micro ATX LGA1155
- Intel Core i5 3470
- Corsair XMS3 DDR3 133Mhz 16GB (4X4GB)
- Sapphire Radeon HD 7870 XT
- Corsair TX 750 V2
- NZXT phantom 410
- Seagate Barracuda, 500gb, 7200rpm
- Lite-on CD drive

Etc: I don't know if this will help, but I do notice coil whine on the GPU ( Most of you guys say its fine ) and I also found that my TX 750 power supply makes a grinding noise when the fan is about to spin, doesn't spin at post, and does move back and forth before it spins. If I had to guess the problem is a faulty power supply, but two in the row from Corsair?

Thank you for the reply. I will flash the updated BIOS tommorow and will update my thread with results, hopefully this will work.

Np. Your situation sounds very familiar with the problems I had when I first build my rig. Tried all kinds of stress test for my hardware and switching the PSU just like you did. When I flashed my bios it solved the issue of the random restarting I had while gaming.

I flashed the newest BIOS (F14). I still get random restarts. What else can I do?
I will also leave Prime 95 and Unigine Heaven on all day to test more stability. Heaven and gaming are fairly stable (15-30 mins until restart ) but once the GPU hits 100% in MSI kombustor restarts still happen but faster.

It's probably the CPU running to high. It should be below 70c at least that how it is for Sandy Bridge CPU's which is what I have. Probably a new heat sink should fix the problem.

I think overheating may have been the cause of the issue, although my temperatures were a bit high they were not even close to tjmax and were just above tcase max. I took off the sides of my case and I get 50-55c on the gpu (Orig. 60-65) and 60-68c (Orig 65-72) on the cpu, northbridge on the MOBO seems to be cooler too. I have ran Prime 95 & Heaven for just over 40 minutes now and the system seems to be a lot more stable. If I put the side panels back on, system restarts and temperature goes up. Again, thank you for helping me with my problem & I will probably invest $30 in a new cooler now. I'll keep this thread up in case more problems arise, but for now it seems great!

Edit: two hours in, even overclocked the GPU. Temperatures are fine and no restarts. Added solution.
