Wait, so you're blaming Intel because your system has a crappy PSU? lol what. The corsair is a good psu...I have a 650tx in one system, and 750 in the other.
Run a cpu stress test like prime 95, intel burntest or linx and see if the pc shuts off If not then run a gpu stress test like furmark and see if you can get the pc to shut off. Keep stress testing components until you can get the comp to shut off like in game. Hopefully you can get it widowed down to the component causing the problem. Good luck
my guess is not motherboard but GFX, what are temps? PSU was crappy, but it seems that wasn't issue. good thing is to check RAM with memtest or similar testing software...
^^^this Prime95 (smal FFT's) for CPU, Furmark for graphic card and then find what is causing shuts off. What about airflow in that case? That rig must have adequate airflow so that hot air can quickly "leave" that case. While gaming or stress-testing hot air can be too much accumulated inside the case causing overheating of the CPU, GPU, MB or PSU (or all in the same time) and after that if only one of those components is overheated rig will do the shut off. Also check the thermal compound between CPU and Intel BOX cooler. Check in motherboard BIOS (Health Monitor or something similar) settings about CPU warning temperature and CPU temp when MB will do a automatic shutdown.
air 1.the case is a cool master case im not sure what model but it has a light blue bezel around it 2.ive added some new thermal compound it lowered the temps ill try what you guys suggested and update you if anything happens
Fans? How many of them and where they are mounted inside the case? Do some pics od case inside and outside and post them here so we can see fans...
Bechmark result from Furmark and max.temperature in Furmark benchmark test they are not so important, do some Burn-in test because that is the main purpose of Furmark: if graphic card (especially OC'ed graph.card) passes without any problem Furmark Burn-in test without artifacts for 20 or 30 minutes then everything is OK with it, there is no game out there that could worm up graphic card GPU and memory higher than Furmark Burn-in test. Also while doing Furmark Burn-in test maximum temps of GPU must be higher on your GTX 560Ti than 55 Celsius on that picture of yours.
Has to be heat buildup if it's time sensitive, either in the GPU or hot spots on the CPU. Are you running software with a custom fan curve to increase fans as temps rise (like Precision X or Afterburner)? And did you apply the thermal paste on the CPU very thin, using a credit card to avoid any gaps or clumps?
its Strange my pc didnt shut down when i ran the test i just cant figure out what it is.i played Black ops 2 for an hour and nothing happened
Try to open the case of that rig as much as you can, remove side panels and place that rig on the top of the table with a lot space/air around it. If you can place near it some big fan to blow air directly to the CPU, graphic card... Then do some Prime95 and Furmark Burn-in tests and play with high graphic details some demanding games like Battlefield 3, Crysis 2 & 3, Far Cry 3... After two, three days if you don't experience sudden turn offs then this is the clear case of some component overheating inside that rig: CPU, GPU or PSU, maybe even motherboard (NorthBridge or SouthBridge). Try that and then come back here with report
Looks like the fan idea didnt work either unfortunately,im trying to sell this system and make a new one with better parts and case i won a Antec Nine Hundred Two 902
Yeah, it sounds like a part that slowly heats up. Could be cpu/gpu if it's borderlining, and it just needs that extra 10th of a degree to fault. But the mobo is a good candidate, because it has many components who's temperature is determined in large part by slowly rising ambient temperature inside the case. -scheherazade
Actually, this is something that happened to me for a while with an incessant GPU driver crash. (this was with an nvidia gpu) I had to run fur mark 24/7 to keep my system stable. It ultimately ended up being remedied by raising various max amps limits in my bios. Only with the raised amp limits could I stop running fur-mark and stay stable. I suspect that the GPU/driver goes into a high power mode if the load gets high enough, but a medium load wasn't triggering the high power mode, and the GPU was being starved of power for the given load. Might be totally unrelated to your problem, but I had to do exactly the same thing to be stable (run fur mark).
