Windows 7 16 gigs ddr3 gigabyte OC to 2133 3570k I5 OC to 4.2 MSi Mpower Z77 Corsair 750 Gold HD 6950 2 gig sapphire card

So my issue I am having is that I have is that my system hardcrashes randomly. It has crashed when under load, when idle, and with the overclocking removed. It crashed 5 times 2 weeks ago and I pulled it apart and reseated everything. Yesterday it crashed 3 more times. After the first crash I have been watching temperature closely and it stays around the mid 40's, hitting 67 on one core once while under a stress load. When the system crashes it goes to try and reboot (get the flicker of light on the cd-rom, fans turn back on) but doesn't. The front panel leds (such as system power and busy indicator) do not light and nothing actually occurs. Some motherboard LEDS light, as well as the reset button, the power button, and the OC button on the motherboard. It will not show any codes on the motherboard though. The computer will stay this way indefinitely until I either remove the power plug for awhile or hit the power switch on the back of the psu and leave it that way. Like I said, I have reseated the power cords and cards; I also cleaned out the case well and have run stress tests on the cpu, gpu, and psu (all the tests passed). It seems to be getting worse on the how long it takes to restart issue.

First thing that comes to mind is have you made any recent changes of overclocking? I would say your CPU is running unstable and probably needs slightly more voltage on the vcore depending on what you have it set as that is. Its also possable your ram could be unstable If its overclocked. The only way to know is Trial and error. set the ram to the default speed and slightly tweak the cpu settings one step at a time and run prime95 to see if it still crashes.

My CPU and RAM have been at stable OC for almost a year. Would the OC leave it with the problem where it won't start for awhile? It is driving me crazy. I have run OCCt and HWMOintor and everything seems fine, though it is readying 12v rail at 8.88v

hmm...that is wierd not starting awhile after it crashes. Only thing I could think that would cause that is the power supply having issues is a failing power supply. They can cause blue screeens, random restarts, freezes, problems booting. I see hard drives and power supplies go out more then anything.
