The problems first began right after the installation of windows. The monitor would garble and/or lose signal reception although the computer was still on and functional (ie, it would continue to install/download/etc). The only way I could get the signal back was by restarting the machine.
After some experimentation I found that the problems happened only with hardware acceleration turned on, and only when browsing Firefox, or working with anything in Microsoft Office.
Lately, after switching the monitor and getting a new video card (the same model), the problems still exist. I have found that by turning hardware acceleration off the problems stop. I like playing computer games though, and of course hardware acceleration is necessary for them. When playing the system seems stable enough, but when exiting the game the screen garbles and such.
Any ideas would be greatly appreciated. Thank you.
