Hey guys,,this is what happened. Im running Windows XP pro on a new pentuim 4 computer. I had "lots' of windows open, minimized down below. I was also in the process of copying a DVD movie in my burner. While all of this was going on, I had two file folders open on the desktop and was drag and dropping files between the two, when this error message popped up(and I wished I could remember exactly what it said, but I cannot)...completly blue screen with this message....."windows has stopped or shut down because of some error, to save possible damage to your computer, if this is the first time you have seen this message please reboot your computer, if this has happened before and computer will not reboot you will have to open bios and blah, blah, blah"(thats what I dont remember). Anyway, I rebooted,,the computer booted up, did its checks on devices and drives, then when it normally opens up to Windows XP, I recieve this message instead...."error loading operating system". Thats all that comes up,,if I reboot,,same results. Anybody have any ideas? My wife uses this computer to run bookkeeping for our local water district, and guess who was going to do end of month billing this weekend! I'm in BIG trouble, unless some one can help me troubleshoot..I would appreciate any attempts to offer assistance.
