Varying Power

[long-fall]

I have a Crystal 500W power supply but...

I was watching the BIOS hardware monitor, and my 12V and 5V power monitor's turn red about every 2-3 seconds, with a volage of 10.5 and around 4, respectively. I know that's bad, but could it be the cause of all my troubles? What happens is that, when I'm booting up windows, or even just surfing the web or gaming, my computer will just stop responding. It's as if it's off, not sending out any signal (i've checked on a few monitors, it's not the monitor), but it's still on. Sometimes when I reboot, it says overclocking failed, while I was not overclocking. For the last three months (since I've built it), it has always had chronic stability problems, it would turn off about once a day. I brought it home for the holidays, and now I cant keep the damn thing on for more than a minute, if it even makes it to the windows screen.

What are your system specs?
I think you need a new PSU.

EDIT:
Okay so I made a boot disk by following the explanations on the microsoft website, and was able to boot it in safe mode, no problems at all. I don't know what to do now...but here is my hijackthis log if it helps:

Well I got it fixed, if anyone has this problem, it's definitely with the power. I plugged the power cord into a transistor with a rheostat, in which I upped the voltage to a constant 125V. Using that, the motherboard voltage, instead of varying from 11.9 to 10.3, stayed within .1 Volts of 11.3V. Basically, it's the PSU. Thanks for the help.
