PSU Issue?

New build didn't have issues at first, but now it seems to be freezing/crashing more often. I thought it may have been a HDD issue, so I changed it, but things only seem to have gotten worse.

Everything in it is new except the videocard, HDD, DVD drive, and PSU. The thing is that the comp I had before this used to restart randomly too, and had issues with the USB mouse losing power. It used those parts listed above. I thought it might be a PSU issue now because PC Wizard says my 12v rail is at 9.72v. (It didn't before, though I dont know how reliable these readings are). I restarted again after posting this and it shows the 12v rail as being at 11.30v again, which is what I've normally seen it at.

Comp restarted randomly.
Comp froze while installing Company of Heroes.
Comp randomly died when I tried to install a program.
Comp randomly died while only playing a game. When this happened, the computer seemed to be rebooting again, but wouldn't. The fan in the videocard was blowing at max, and trying to restart the comp with the power/reset buttons did nothing. Had to cut PSU power. It was after this that I noticed the voltage for the 12v rail was at 9.72v

Specs:
e4500 at stock
EVGA 650i ultra
2x1GB OCZ PC6400 (Yes, correct voltages)
Antec 530 Watt Truepower 2.0
160 GB Maxtor HDD
x1900xt

Temps are fine. 29/30 for CPU, 60 idle for GPU

Voltages according to PCWizard:
+3.3V-3.26v
+5v-4.75v
+12v-9.72v (changes back to 11.30v, however)

Also, I don't know if this is normal or not, but when booting up, a red LED glows on the videocard's power connecter for about a second.

Have run orthos and memtest with no errors.

If possible, check the 12-volt rail with a multimeter.

Ok, I checked with a multimeter and here are the results:

12v rail: at least above 12v, tested molex first time. Second time (reboot) using PCI-E and main mobo conector thing was around 11.85v
5v: 2.72v or less idling, with molex. Second time 2.56v using molex or main power connector
3.3v: 2.27v first time with main power, 2.16v second time.

Coincidently, after running orthos there was an error while I was testing the voltages.

This is as accurate as it can get, right? The voltages seem really bad for the 5v rail...

If the power supply is putting out those voltages, it's time to get a new power supply.
