Possible PSU Issues

I'd like to know for sure if this is a PSU problem and not any other form of problem. I've had the Sapphire Radeon HD3850 AGP card for about a month now and its ran smoothly on XP for about a week or 2 but recently I've been getting lock-ups, VPU recovery, BSODs, random crashes, and multiple errors.
The first thing that popped into mind was drivers as the card is known for driver issues, So I tried many different drivers including Omega drivers and the problems still occur. I only know that my psu is a 500 Watt Coolmax with 2 +12 rails that add up to 34amps which should be plenty but, I've had it for a while now so I'd like to know if its the culprit for these suddenly random issues.

Well its not a virus ive done many freash installs, its not the video card it runs fine in another comp and no i've got an asus P4S800 mobo so no onboard video.

I have tried that but my rig is more of a power muncher then the other one as the rig i tried it in had 1DVD-RW 1HDD and 1 fan mines got 4 fans,2 HDDs,2 DVD-RWs the psu that i tried had only 29amps on the +12v rails so that wouldve been a no-go in my case

The Crapmax 500 is labeled for 34 amps, labeled wattage shows just under 32 total, if it were capable of that I'd really be surprised.
If you tried a known good 29 amp psu ( what is it ? ) and it didn't power up the system, your 32 amp Crapmax was never really enough.

I'd like to add also that under a prime95 torture test my OCed prescott reaches 57 degrees Celsius and my +12v reads at 11-11.07v but all other voltages are where they should be.

Doesn't sound bad for an oc'ed P4
Unless you've checked the voltage with a DMM, I wouldn't worry about software readings.
If you have checked with a DMM, get a new psu.

Higher quality , lower wattage, still plenty of power for your system
