this computer has geforce 6150 onboard graphics. never had any problems when i used to have a 19" CRT on this computer and ran a resolution of 1024x768 or 1152x864. i recently got a hand-me-down 19" LCD for it and every time i switch to the native 1280x1024 i get a black screen with a 1-pixel thick blue line across the very top and pressing ESC doesn't revert back to the old resolution. but the computer seems to be functioning still because the harddrive light does show activity. weird. but if i reset it at that point, it will boot into windows at 1280x1024 just fine. but if i go into standby and wake it up, i get the same black screen/blue line. at first i thought it was a problem with the monitor so i lugged the old CRT back out and it showed the same thing! has anyone ever heard of this? i uninstalled the video driver and reinstalled with no change. any other resolution, including 1280x960 that i'm using right now, works fine.
