I have a Emachines T6212 with ATI raedeon 2600 video card w 512 mb, and 1.5 gigs of ram. I have been getting a no signal input and then a black screen from my monitor while playing WoW and AoC. I have systematically done everything I can think of to solve the problem but was hoping maybe someone else might have other ideas... this is what I have done. . Checked and updated all drivers. . Upgraded the powersupply. . Upgraded the video card.. this solved the problem with WoW but not AoC. . Checked and updated Drivers again. . Got a new VGA cable for the monitor. . Got a new monitor. . Cracked the case for airflow.. Nothing is hot in there. . Cleaned it with compressed air. . Set to optimal settings in Bios . Changed MSconfig to only run needed programs. . Ran a registry cleaner, diskcleaner and defragger... I'm doing whatever at this point. Please any other clues as to what might be causing this, I really don't want to have to buy an new comp.
