Okay so a few days ago my GPU (EVGA GTX 660) started to play up, I was in game playing SimCity5 (hey comon it's a good game!) and boom my game crashes and windwos pops up an error "Display driver stopped responding & has recovered" I didn't do any hardware or software changes and considering running EA's catastrophe I thought it might be a one off. So later on I start SimCity up again and this time micrsoft greets me with a BSoD again relating to the GPU. I reboot and try to run 3DMark11 and again the system crashes with a white screen not even a BSoD this time! Then I started up EVGA's OC Scanner and tried to do a benchmark, this time I got a black screen but the system did reboot, tried this multiple times but on the 3rd try it worked fine (Even disabled all non microsoft services the 2nd time in msconfig but looks like it wasn't a software issue). I went to Nvidia's webstie and realised new drivers were out, uninstalled the old ones and still has a problem. Up on contacting EVGA I was told this was a TDR (Timeout Detection & Recovery) service issue, I read the forum post on EVGA's webstie and this mentioned that the TDR issue can be caused by a problematic PSU, however there were about 10 different possibilites listed. So considering it a GPU issue at the time I ran off my integrated graphics and the problem didn't occur. However EVGA mentioned that I reinstall drivers while in SafeMode which I did and there wasn't any problem for a day. Now i'm watching a Youtube video and my system decides to turn off without any warning. I took out the GPU and tried to start the system however when pressing the I/O button the PSU fan just spun up and then stopped this kept on happeneing every 5 - 10 seconds untill I unplugged the thing out from the power socket. My PSU has a dynamic fan which only spins when exceeding a temperature threshold, but in this case the LED on my PSU was also restarting and the LED on my WiFi card was also switching on and off which most likely means either my PSU's gone bad or my motherboard. I've contacted EVGA and Corsair but Corsair still hasn't responded, anyhow here are the System Specs:
Corsair GX600 600W
i5-3570K
GTX 660 SC Sig2
MSi G43-Z77a
Corsair Vengeance 8gb 1600MHz
x4 Corsasir fans (120mm) overkill maybe? (Doubt any of these put a strain on the PSU)
Gigabyte GC-WB150 WiFi card PCIe
Samsung 840 1SSD/ WD HDD 640GB
Now the damn thing won't boot up, just does that cycling thing and I don't know if it's the mobo or PSU, but considering a few days ago my GPU was having the above mentioned issue it's possible the PSU couldn't supply enough power to it hence why it crashed while running fairly intensive programs? And now maybe the PSUs blow a cap? and thanks for reading guys
