I logged onto the computer this morning and shortly thereafter the computer crashed. There was a long message on the screen that was up there for only a few seconds, before shutting down. It said something about, "if this is the first time..." and something about hardware. That's about all I could read before it went away. So I restarted and several minutes later the computer crashed again. So I reatarted again and the same thing happened a thrid time. I restarted once more and ran a virus scan - nothing. It looked like it was going to crash yet again but didn't. Any ideas?
