Is my PSU the problem?

I have the following setup

Thermaltake Armor Series VA8000BWS Black Aluminum
GIGABYTE GA-P35-DS4 Rev. 2.0 LGA 775 Intel P35 ATX Intel Motherboard
Intel Core 2 Duo E6850 Conroe 3.0GHz LGA 775 65W Dual-Core Processor
ARCTIC COOLING Freezer 7 Pro 92mm CPU Cooler
CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
ENERMAX EG851AX-VH(W) EPS12V 660W Power Supply
+3.3V: 55A max, +5V: 48A max, +12V1.2.3.4: 20A max
(the power supply is from my old computer and is 2 years old)
EVGA 512mb G92 8800 GTS graphics card.
Western Digital 150gb Raptor primary harddrive with Win XP
2 x Seagate 320gb harddrives
Soundblaster XFI Xtreme music

My computer reboots during games and when I run prime 95. Prime 95 reboots at different times during the torture test, but I do not see any errors. I receive no errors and even unchecked the automatic reboot on error under the advanced tab in system restore. I am operating at stock speeds and my temperatures are all normal. I ran memtest for over 8 hours with no errors as well. According to PC Wizard my voltages are as follows.

CPU - 1.36V in BIOS it is set a 1.375, and when BIOS is set at 1.35 PC Wizard shows it as 1.33V
DIMM - 3.28V
+3.3v - 2.13V
+5V - 5.12V
+12V - 13.4V (Is this too high?)
VTT - 2.13v
VBAT - 3.14v

So what would you think is wrong? PSU or something else. I posted this in General hardware earlier, but after running all these tests I am leaning towards PSU.
 
If you are overclocking, have you tried running different things a bit slower to see if it helps?

You might want to check the voltages coming from the PSU with a multimeter as the problem might be that your sensors are giving bad readings.
The VCore reading is a bit high but then again those sensors arent exactly accurate and some will be way off.
If you can find a measuring point for VCore on your motherboard you should be able to measure it if you are careful.

ps if the 12V reading is correct, it is too high.
Also 3.3V is too low by a long way!

Given you have an unstable PC and those readings are a bit all over the place , I'm inclined to believe the PSU is causing problems.
