This has just started in the last 2 days. Till then it ran great. I have the following hardware: MSI p45 neo 3 motherboard E8500 3.16 ghz wolfdale proc 4gb corsair xms2 6400(800mhz) 74gb western digital raptor visiontek radeon 4850 vid card I have xp as my boot on the main disk and windows 7 on my second harddrive running thru dual boot manager at start up. I am not overclocked at all. The error screen goes off the screen pretty fast. I could read something about it looking for a clock reply from a second processor and failing to get it. the error msg contains something about ati so I am thinking its got something to do with my vid card any ideas?
