At some point my 32mg Radeon 7500 wasn't cutting it for modern games, so I got a 7000 with 64 mg because that was the most advanced thing I could find that would fit in my machine. I got it, installed, and it worked- for about five minutes. Then the screen went blank and I couldn't get any response out of my monitor without reinstalling my old card. I got the card second-hand, and it came without a disc, so if there's a driver I need, I wouldn't know how to get or install it. After switching my cards back and forth about a hundred times with the same results, I've given up on figuring this out myself. Is my card broken? Do I need a new driver? Is there an "on" switch on the card somewhere I've missed?
