Well let's see here. It all started the other day when I exited out of a game (WarCraft III). All of a sudden there were Vertical lines through some of the screen (hard to explain, and they won't show up in screen shots...Which means it's probably the hardware right? :\) I've tried reinstalling/removing/updating video drivers, chipset drivers, using system restore, and even reformatting. Nothing seems to fix the problem, and it's difficult to explain what it is exactly. Sometimes there's weird lines around the cursor, other times Win XP won't boot up at all. Because the screen goes black. I had to go in and try to fix things using Networked Safemode, but nothing seems to work. My guess is it's either the graphics card, the card's bios, something :\ Let's see, everything is really new, ordered off newegg.com. We already had to get replacement motherboard/cards because they were faulty/broken when we got the first ones. (Sorry if it seems like I'm rambling) My comp specs: 80 GB Western Digital HD Nvidia Ge Force 4 Ti 4600 Asus A7N8X Deluxe MB Nvidia Force 2 Chipset AMD Athlon XP 2600+ Samtron 75E Monitor Corsair XMS 2700 (512 DDR) with 2-3-3-6 MT's I'm not sure what else to try. Maybe messing around with the Bios or Vid Card Bios a bit, but I don't really know what I'm doing. It seems to run fine in Safemode with 32 bit color, 16 only brings vertical lines. Oh yeah, different modes (ie: resolution, color, etc.) affect how much clutter there is too. Like, lines all over the place, whatever. Seems to be best on 800x600 32 bit color, 16 bit makes it go to hell, or even shut off. So, device failure or what? I basically can't boot up now without having this problem. Sometimes it doesn't boot up at all. Sometimes if I change a setting the comp reboots automatically. I've tried virus scans and all that, no flashed bios or video card bios... Any ideas? At the Moment I can't even get it to boot up without safemode, the screen just goes totally black after the windows loading screen, nothing happens, and I have to power down. Edit: Also, I've tried hooking another monitor up, same effect. Which makes me certain it's either the video card or something in the bios.
