Desktop Keeps Restarting at Post!?

Over the passed couple weeks I've had issues with my desktop where if I start up/restart the system, it'll keep restarting over and over at the post screen(or at least I think it's post, it's just all black with a couple of white "-" and a number/letter in the bottom right corner). Normally if I just unplug the system for a while and let it chill for 5-10min, it would boot up as normal once I started it up again(this restarting issue wouldn't happen every time I boot my computer, but at least 70% of the time it would). I knew this was a problem, and I've tried doing research about it to try and figure out what the issue might be, but I can't find any reliable info about it anywhere through google, and I just haven't had the time to dig deep into the situation.

Also I should probably add that during the time that this restarting issue started happening, sometimes the system would go straight to the bios screen without me pressing f11 or whatever the key usually is to go there, but all I would have to do is exit out of the bios and the system would boot as normal, but this hasn't happened too often.

The big problem is that just now, I restarted my computer for a windows update, and now its been stuck restarting at post for 2 hours. I've already tried letting it sit unplugged for an hour, and nothing is happening. I can't get to the boot manager, safe mode, bios screen, or anything. All that happens is it shows a black screen with a symbol for my monitor connection like it normally does when I'm booting, then it goes to the post screen, and just repeats this process with no beep codes or anything like that.

I have so much work to do and when I need to get it all done on my desktop, this is very hard and very frustrating to deal with right now.

I've never had any issues with overheating or anything like that, and I monitor my GPU/CPU temps constantly. I know it isn't a virus causing this, because I know enough about the subject to keep myself entirely clean.

Here's some of my specs for whatever might be of help:
OS: Windows 7 64bit
RAM: 12g
CPU: Intel i5 2500
PSU: 850w

Thank you for your help.
 
First step I would try is to clear the CMOS. Remove the battery on the motherboard with the power to the PC disconnected. Leave it out for a minute then put the battery back in, connect power then boot. Some motherboards have a button or a jumper to do a clear CMOS but removing the battery works for all models. First thing I try in situations like this since its easy to do and free.

OK James I think were getting somewhere. I just reset the CMOS, and now I'm able to boot my system into windows. Is resetting the CMOS normally just a temporary fix? or could that have been the entire source of the problem?
 
Foremost it was to get you back into the system. However this could permanently resolve your issue as well. Sometimes you can have things like static electricity cause corruption of the CMOS memory, removing the CMOS battery flushes that memory, and forces it to use the ROM(read only memory) that will not have been corrupted.

With all that said my gut tells me you will still have the random restarts. What you describe sounds like a power supply issue. I would double-check that the 4 or 8 pin CPU power connection is plugged in solid. Other than that it really sounds like unstable power issues maybe related to a faulty PSU.
