Yesterday, my father got an error on every website due to the wrong update and he updated the program. After that, the program asked to reboot the PC, but ever since, the monitor has no signal. Windows is starting up, even the ‘welcome sound’ is playing, but the monitor is giving no signal. Not even the messages from the bios directly after startup are being shown. He has tried a different monitor.
What could be the problem, and more important: how can I fix this on his computer?
He is running Windows Vista and the Avast Pro version.
Thanks for the suggestions, I’m going to swap the videocard to see if this is causing the problem. Rather weird coincident if it really is a hardware problem. Unless my father got anger with Avast and hit the computer to cool off
