Hello Bleeping Computer forums! I've been lurking around using others' threads to find fixes for my computer issues, but recently I've come across something I haven't been able to fix on my own. Recently, I was playing Borderlands 2 when my screen dimmed out and then went completely black. My computer didn't crash, and I was able to use audio to save and exit to windows before restarting, but when I rebooted my display wasn't restored. The back light goes on and off a few times like it always has, (there's nothing wrong with the monitor, but the computer has a half-second pause between the first few screens) but no image is actually shown, just a black screen. I don't get a no signal error, and I'm able to log in blind, though obviously I can't accomplish much from there. I've tried uninstalling and reinstalling the latest drivers and reverting back to the drivers on the disc that it came with, but every start up gives me the same thing. I've tried checking connections and changing the power supply chords as well, all to no avail. Everything works fine with my old 3400, so I'm fairly certain this is a graphics card problem. Anyone have similar trouble and know if it's fixable?
Edit: Forgot to mention that the card has worked for about two years, and the fan was replaced about four months ago.
