I'm running VISTA home premium. I have the McAfee virus protection provided free through Comcast.
After my computer has been running for a while, my screen goes blank. It usually goes white but once it went black and a couple times it went dark red. I cannot restart my computer without unplugging it, plugging it back in and turning it back on. When I turn it back on it goes to Safe Mode. I've run AVGAS and Ad-Aware and they aren't finding anything. When I try to run a McAfee scan, the screen goes blank again. This has happened in the past and I have been able to get rid of the problem by running disc clean-up, McAfee Quick Clean and deleting temp files, but this time it isn't going away.
Also, when I check Windows Security Center, it says that Windows did not find anti-virus software on this computer. It also says that Windows Defender is turned off and won't allow me to turn it back on. My McAfee Security Center says that the software is running and working fine.
I don't know if these two conditions are related or not.
