8500gt quit dual monitors?

[thecomputeraddict]

Okay, so I recently recieved an pny verto 8500gt from my mom so I can run dual monitors on my pc for school. But it has quit working maybe after a week or two of usage. I went out earlier and before I left it was working fine, Then I came back, and my second monitor quit working. I checked the cables and stuff but still nothing. I'm thinking it may be a vista problem. I was planning on installing xp back on my rig for numerous reasons. Any help would be appreciated.

Sounds like you have a bum videocard to me. You tried the monitors on other computers, and tried a different confirmed to be working video card? You made sure the video card is completely locked in the motherboard?
