For about a year I have been having an issue where the computer will randomly stop sending a video signal to the monitor. This has happened on two different monitors so I know that it's a problem with the computer itself.
The problem would often manifest itself when changing resolution (e.g. when I load a game) or if the computer went to sleep I would get no video signal when I woke it up.
In the past week the problem has reached the point where half the time the display will work fine for boot up but lose signal when the Windows login screen appears and the other half will not get any signal at any point. I suspect the video card may be failing but I don't want to spend money replacing it unless I'm 100% sure that that is the issue. How do I go about troubleshooting this issue? Thanks
