I've been getting the above error recently. in the event log they seem to happen simultaneously. plug and play/power source/dcom terminated unexpectedly. windows must restart. it's not so bad that I can't use my computer. just a tad bit annoying. the error message comes up and then forces a restart. it mostly happens in the middle of the night when I'm trying to seed torrents. broni over in the malware section has inspected my logs and says it's not a malware problem (googling these errors inevitably leads you to malware forums. that's how I wound up here.). he suggested I post here and see what y'all could do to help out. I'm running windows 7 ultimate 64 bit on intel i7 processor. let me know what other information I should provide. much appreciated!
