I just had the most annoying issue with my current system and I thought I'd share to see if anyone else has had the same issue...
I ordered NOD32 antivirus for my new system. I had avast! installed. I uninstalled avast! and restarted my computer, only to be greeted by a black screen and the OSD on my monitor telling me that no signal was detected. I had to grab my old monitor and plug it in. For some reason my system would NOT boot with my newer monitor until I completely removed all catalyst drivers as well as monitor drivers for my old monitor. Why uninstalling avast! did this is beyond me! It now works, I had to reinstall all video/monitor related drivers. Took me a couple hours to figure out what to do... talk about annoying.
