Hi, thanks for responding. The computer won't stay on long enough for me to do anything. It comes on, I get to the screen that tells me it didn't shut down properly and when I try to go to safe mode, it spontaneously shuts off. I've also tried to just let it start normally and not in safe mode and it also shuts down then too. We are using Windows 7. This is not my main computer - my husband uses it exclusively so I was not using it when it shut down. He said he was just doing his normal stuff. A friend who works in IT suggested it might be a fried mother board or could be full of dust (although we do open and clean it periodically). I tried to turn it on again today and it did the same thing.
the system had a full scan about a week ago and nothing was showing up, we do all installs of any critical updates that windows sends. I suspect it has just kicked the bucket as it is about 8 years old!
If you have any suggestions on how to keep it on I'd appreciate it. I need one file off that computer
