I just updated my avast to version 9.0.2011 for windows 7 and was told that a restart was required. Once I did my computer no longer boots. The fans all run and the motherboard lights up to signal that it is working but I’m not getting a signal from my monitor, keyboard and mouse. I cant log in so I can’t restore from my backup. Has anyone else had this problem or have an idea of how to fix it?
Could you give a bit more information on what OS you’re running and any other info you can think of.
Updating your AV would not do this,it sounds more like power supply problem.
Have only rebooted once or, have you tried several reboots ??
Have you tried getting into Safe mode ??
