I am having trouble diagnosing my what is the culprit for my PC woes, either MoBo, GPU, or PSU.

So I am having an issue where my PC will randomly hang, and the my monitor says "no signal check cable blah bah". My PC is still running, but it's frozen (it's not my monitor at fault, the PC is indeed frozen, no sound plays and I've tried different ports and cables). When I turn off my PC (push and hold power button) and reboot my PC, it often wiill not Post or not show any picture (but I never hear the Windows 7 startup jingle, and the lights on the MoBo still glow).
I doubt it'sa GPU issue since if I wait a long time my PC will work, but after a long time it will hang again, and remain unusable or unstable for a long period before going back to normal. Temps are fine, I've dusted.
People say it could be a motherboard issue, but some have said it could be a PSU issue. I think it is a PSU issue at the moment, because of this thread I made on the Gigabyte forums:

I'd recommend reading that thread btw, it will answer allot of questions you may have.
Specs: Gigabyte EX58-UD3R, Intel i7 920, ATi HD5850, 6GB DDR3, Corsair HX850W
I hate how there are so many possibilities :pwn:
It could be the PSU but without having it properly checked or trying a replacement there is no real way to tell, one thing you could do is check the voltages in the BIOS or HWMonitor to see if they are low or fluctuating a lot.
This sounds very much like a bad capacitor.

I should note (I believe it's in that thread link but I'll say it here anyways) that that PSU is a replacement for one that I had a loose pin on (It was a dumb problem, probably my fault for using the paper clip trick too much, but Corsair is cool and replaced it).
After I got my replacement PSU, I ordered an SSD to replace my ailing drive, so my PC usage was very limited for like a month. I initially thought the SSD was causing the issues since they started soon after, but that can't be it since the issue persists with the SSD removed from the system.

Can we pretty much rule out it's not the GPU though? I am pretty sure it's either the MoBo or PSU. I will keep using a spare PSU and see how the system is, but that PSU is some off brand lower end model, but the PC runs fine for now, I guess I won't push my luck playing games for a bit.
I don't think the GPU could cause anything like this so you can rule it out.
Since this started not long after you got the replacement PSU I would consider this to be the most likely cause.
If it only happens after using the computer for a long time, and it only goes away after letting the computer sit 'off' for a long time, it makes me think something is overheating.
The videocard is easy to rule out- get a cheap ass card(borrow one if you don't have an old one laying around) and try it.
Other things I'd look at: Are you even getting power to the motherboard after it shuts down? I mean even if the computer is having trouble you should be able to fire it up to see your bios screen. If you can't get that far that means you probably are not getting power from your PSU at that point. If you are getting power but can't see the bios screen, then that suggests it's a videocard issue.

Well like I said I swapped out PSU's and it seems fine. But realize that it seems like if I do any change (change PCI-Express slots, unplug and replug, etc) everything seems fine...until it isn't.
I'm pretty sure ruling out the GPU is fair.
So I am using the PSU I am suspicious of in another PC, everything seems fine. I guess we can confirm it's a MoBo issue?
The guy on Gigabyte forums says it could also be a CPU issue though, something about the connection could be bad.
The pins seem fine to me.
I doubt it's the CPU unless you put them in with a hammer.
So the motherboard you'd say? Cause the PSU is fine, the PC I am using it in has no issues.
Everything seems to point towards the mobo having problems.
What's a good LGA1366 board you recommend? This board is known is to have issues according to Google.

Any of these boards good?
