Today when I got up and turned on my computer it took me to the safe modee/normal mode screen and I hit normal mode then after that it went to the loading screen and for a split second a blue screen popped up and my computer reset. I've tried safe mode, safe mode with network, safe mode with command prompt and none are working they all have the same result. Yesterday I had a virus warning of a Trojan downloader but Windows Defender said it was successful in deleting it when I tried. In the report it didn't say the virus was in a system file but I'm afraid it was and I deleted a system file in which case I'd need my xp disc but that's at my other house and I won't be going there for a while. Does anyone else have any solutions?
