Power Supply Issue?

Suffering from some computer problems, here is the story.

Recently, I was gaming pretty hard, about my fourth hour into WoW, when suddenly my computer froze, the screen began to tear, sound was fuzzed, and I was unable to alt tab, ctrl alt delete or do anything to get out of the freeze. I rebooted, started playing again, 60 seconds into playing, same issue. I decided to reformat my hard drive, did that, got all of my drivers updated, loaded up bad company 2, as soon as it started to load, the computer shuts down. Tried it again a few more times, computer either froze like it did before, or shuts down. I decided to clean out the dust in my computer. Tried turning on my computer again, it would shut down or freeze anytime I tried to perform a substantial task, like load a game or watch a video. Called an IT friend of mine, he said it was most likely the graphics card, so i got a new one that uses more power. After I locked it in and fired up the CPU, it shuts down or freezes as soon as I load up windows. I run it on safe mode, computer runs fine with no errors on safe mode for 30 minutes, during that time i check hardware malfunction logs and other logs to see if there were any recorded errors, they were all blank. I update as many drivers as I can from safe mode. Restart. Computer makes it 30 seconds into the boot phase and it freezes. I let it sit for a while. Try it again, it turns on for about 5-10 seconds, then shuts down, then turns itself on again, then shuts down, it repeats this process 3-4 times until it gives up. At this point, I am almost positive it’s my power source. I have had it for more than 3 years now, and it has received a lot of use. I just wanted to get some other opinions before I spend any more money. Can’t get my system specs at the moment, but at this point I think it’s irrelevant.

Any thoughts would be much appreciated.

Power supply is "hec" "AcePower" 580W. Cant boot into BIOS wont stay on long enough.
Most shutdown problems can be attributed to overheating or power supply.

Do you have another or maybe borrow another suitable PSU to test.

It would seem as though you have a bad PSU.
I have never had any problems with overheating and the power supply is old. I have a friend who has an extra power supply, my next move was to use his and see if that solved it. I just wanted to make sure that random shut downs could be related to a bad PSU.

I really appreciate the help.

My only other question, is it possible for a bad PSU to cause my computer to freeze?
Yes freezing is also one of the symptoms of a failing PSU.
Excellent, thanks again for all of the help!
