my Radeon 9800 Pro passed away on the 27th, and compusa's replacement made it so I could replace it with a Radeon X850 XT. I got the video card but there was a slight issue any time the video card did too much acceleration my system froze and had to be reset.

--current hw list--
Asus A7N8X deluxe (fried) being replaced
Radeon x850 XT (fried) compusa took it back declaired DOA
Athlon XP 2500+ (seems ok core looks fine) replaced with athlon64 3000+
1.5 Gig kingston ram (tests ok)
100gig 8meg hd makes normal spin up and read sounds
pioneer 8x dvd-rw looks fine can't tell if there was any damage
sb audigy2 pt still works tested it in another machine

so I got my new antec neopower 480 watt psu installed it plugged all nessicary hw, system does not boot at all no fans come on. so I remove everything except CPU fan and vid card. System turns on CPU fan is moving system is beeping bad video card code. just for further testing power on CPU with no vid card and HD's plugged in they spin up and sound normal. So I remove the video card and take a look at it, one of the traces is fried completely, I take a look at the AGP slot and there is a burn mark exactally where that trace that was fried out of existance was.
I think what may have happened that the POS case was old and shakey may have disaligned the card when I was installing the PSU but something tells me that it may be the PSU though I don't have a PC that I can use as a test machine in the event it is the PSU. So here is my question what does it sound like that has occured here? did I have a bad vid card from the get go? could the case have misaligned the card and caused that to fry the board and card? or what is the best way to test the PSU because I only have 3 days to report it to newegg DOA?
