Frustrating Boot Problem

[Drunkinsquirl]

I Got a Thermalright xp-90 yesterday since stock cooling wasent really doing as good of a job as i wanted it to. After installing, i booted into windows, my proc was idleing 12 degrees cooler and all was good. I thought what the hell ill push it a little further, i rebooted and tried to push the proc to 3.4, wouldnt even post. So i thought whatever, maybe i didnt have enough voltage or whatever and proceeded to clear the cmos on reboot i tried pushing it to 3.3 ghz, it posted and for a second seemed fine, but then when it got to testing the memory it froze. At this point i was a little woried so cleared the cmos and tried to boot with the stock clock (2.8) and it still froze on the moemory test. So i take a few minutes to curse myself out and then cut the power from the psu, then hit the power button like 30 times to drain the caps. I Reboot and it gets passed the mem test (now i feel a little better) so i hit delete to get into the bios and reset some other setting, i get into the bios only to realize the bios have frozen and arnt taking any commands. I strip down my comp to just mobo, proc, grfx card, ram, and psu. I have 2 sticks of ram so i tried booting with just one, than the other, it freezed both times (unless i drain the caps).
I have both an agp and a pci grfx card, and tried both by themselves and it still freezes on the mem test (again, unless i drain the caps). Every time i discharge the caps and it gets past the mem test i can always get into the bios, but thats where it freezes most of the time. On occasion i can get 2 or 3 clicks in before it freezes. Once i was even able to hit f10 (save and exit) and enter, but when it got to verifing dmi pool the screen just turned black. So basicly i've narrowed it down to the proc, the mobo or the psu. I have a feeling its the mobo because it has been slowly dying, N/B fan died several moths ago, Onboard nic stopped working like a month ago. Im going crazy here so if anybody has any suggestions or ideas about whats casuing the problem....

I'm sure you checked this, but your xp-90 is still making good contact with your CPU, correct?

yeah, my proccesor ran fine for a day idleing at 37 degrees and the xp-90 is still firmly seated in place.

Since my comp kinda worked if i discharged all the caps i decided to leave it unpluged last night. When i got up this morning i was able to get into the bios, make all neccasery changes, then reboot into windows with no problem. At this point ive rebooted like 5 times and still no problem.
