OK I got a new video card for my computer, it was a Radaeon X1650 512 AGP for a upgrade from my old cheapy 128 card. Well the card ran ok, but I only had a 200w power supply and I needed a 350w. So I went out and bought a 450w power supply and installed that. Well when I went to run it up, the monitor was getting no output at all cant even get bios to come up. So I pulled out the new video card and it turned with the on-board video it ran just fine. I put the old 128 card back in and that worked fine too. So then I thought it was the power supply and I put the old one back in, it still didn't work. The computer sound different when starting up with the new card. I tried to pull the battery from the motherboard, that didnt work. So is my video card died?
