Could my PSU cause prime95 to fail? (Neopower 480w)

Prime fails within 30min - 2hrs, i changed my gpu cooler and forgot to plug in the molex connector (6800gt) which resulted in a high pitched squeal. Is this normal? Could this have borked my psu. I dont get random restarts or lock ups however i have blue screened in 2 games twice with a restart before i could read the error. This may have been caused by enabling fast writes which i have now disabled. So could this be my psu causing the prime fails? i have pluged in a 380w truepower and primed 4hrs stable but this may just be luck. I have a 7800gtx + asus A8N premium here to play with and i need the neopower to power it up!

Edit: Im not doing any overclocking apart from the gpu, all other settings are stock. Also i have ran memtest for 6hrs without issue.
 
I have a 6800 GT and have forgotten to replace the molex connector once or twice. I got the high pitched sqeal so I shutoff comp and pluged in the connector. Everything went fine and I didn't experience any problems with games or anything. I'm pretty sure same would go for a 7800 GTX. I guess you should try turning the overclocking down a notch and see if you get the same problem. Also im not sure if that 380W truepower is up to par. O and that could not have broken your PSU.
 
Are you running 2t or 1t?
Search my recent posts to see where I am coming from.
I tried 2 power supplies myself, no difference, and one is just some basice thing that came with the case. I was going to throw it in the trash, but glad I didn't as at least I know that isn't my problem.

PS. you can check the voltages with nvidia monitor and asus probe and everest.
Of course those are the voltage on the mobo, not right out of the power supply wires, itself.
 
Oh, I ran memtest too, no problem like for 8 hrs.
Prime is the problem.
Along with blue screens of crashed code running in the Kernel.
(Code running in the Kernel is supposed to be heavily tested, and thus more stable than
a program running at a higher level in the system). But blue screens can be from bad drivers and not hardware. It depends on the hex code of the error.
