I'm hoping someone can help me with this issue as I've been puzzling over this for a couple weeks.
In December I built a new gaming rig.
Components:
Cooler Master - HAF 932 Advanced
Asus p8z68-v pro/gen3 MB
16gb corsair vengeance RAM (4 x 4gb)
Ultra X4 1000w gold PS
Nvidia geforce 550 Ti 2Gb vid card
corsair H80 cpu cooler
Hitatchi HD 6 gb/s 1 tb
Running windows 7 64bit OS
The symptoms:
Sometimes the system runs fine for hours. I can game and have no slow downs or ill effects. However, every once in awhile, it will power down completely as if someone pulled the plug, then after a couple seconds, try to restart itself. Sometimes it is able to boot back up and other times it simply powers down again and tries to reboot until it stops all together. At this point, I have to unplug the PS for awhile before it will power back on again. Sometimes it shuts down before even having a chance to boot to windows and sometimes it can be on for hours and no problem.
What I've tried:
At first, I thought it might be a heat issue. However, under load, my cpu and MoBo never get above 90 degrees Farenheight! This system usually runs about room temperature with the liquid cooler and the fans. I can put my hand on any heatsink inside the unit and they are cool to the touch. This rules out overheating (Yes, the Bios shows my MB and CPU around 80-82 degrees Farenheight)
I thought it might be an OS issue until it happend when I was in BiOS looking at something. That rules out the possibility of it being a driver or software issue.
Then I started getting methodical thinking it might be a hardware issue. I checked the BiOS battery and that was ok. I took out the video card and ran it in another computer and it ran fine without any issue. I tried swapping power supplies but still have the restart issue. I changed cords to the power supply and it did not help. I tried booting up with 1 stick of RAM in the correct slot and still had the issue. I tried running memtest, and it passed 2 full passes with no errors and then the issue restarted the unit. I was so frustrated that I RMA'd the whole motherboard and they tested it and said it was fine. The last thing I tried was installing my video card in the other PCI express slot, and I still had the issue. I made sure there wasnt a short from the motherboard to the case somehow. My voltages in my bios are all well withing operating parameters. I tried going back to my default bios setting, no luck.
I thought it might be an older BiOs, so I successfully flashed to the new version. This did not help the issue.
The only thing that I cannot test is the CPU itself, but I'd imagine that if it were the CPU, then I would not be able to run stable for hours and hours. Today, I can barely even get the unit to boot at all. I'm at wits end with this one and want to throw it out the window. What am I missing???
