did you put in the 6pin power connectors and seat it so it doesn't move in the top x16 slot?

sounds like your system is shorting or the bios is having issues..

Try removing the mobo battery for a few mins. see what that does if anything at all.

thanks for the input guys, i actually discovered my problem, i had to plug another 4pin connector into the MB... maybe it was underpowering.

ive installed the latest drivers and its working fantastic, best gameplay i could imagine.... Only small thing every time i boot my computer it keeps saying ''connection wizard has found new hardware" i keep telling it to piss off but it keeps coming back even tho the card is totally installed and appears to be in my control panel working perfectly.

any ideas?
