I have an older Gateway desktop PC (Model E6300) that I've finally gotten around to upgrading. I upped the RAM to 4gb (which is max supported); everything worked fine. I also had a couple of PCI-E video cards laying around so I figure I'd do that as well, while I had the cover off. This is where my problem begins...
I installed an ASUS GeForce 8500GT (512mb); everything worked fine. I noticed I also had an EVGA GeForce 9500GT (also 512mb), so I popped it in. Everything was working fine, but I noticed that the driver was out of date. I update the driver, restart my computer and now the video doesn't work. It will boot up to the windows loading screen (at the moment it still has archaic XP but my next step after the vid card update was to install win7 64-bit), but at the moment windows is supposed to start the screen flickers and says NO INPUT. I've unplugged and replugged everything I've recently installed and nothing seems to make any difference. I even popped out the little battery on the MB in case there was something in BIOS that was not allowing it to boot. I will mention that I am using the S-video out of the EVGA card, so it may just be a faulty connector but the only other outputs it has are DVI. I have a cable/adapter on order to test those as I use my TV as a monitor.
Also, I was going to just go ahead and use the ASUS card since it worked to begin with for now, but when I installed it again the computer doesn't even try to boot up. It powers and the vid card fan spins, but that is all. So I am also confused as to why it won't work now when it worked fine before?
