Any idea why it's crashing? Are you sure the hard drive is sound?
If you are having a problem again this soon, it may be a hardware problem.
I just had a nightmare with my work PC. I got the blue screen of death a few times a week, but a quick shut down and it went back to normal. It was very frustrating since the BSofD didn't give me any good info to work with... Well it crashed real good. I couldn't even start in safe mode. Not even with the start-up disk... In the end, it was the on-board NIC that went south. Once I disabled it in the bios and added my own card, everything worked out... So the lesson, maybe you are having a intermittent hardware problem...
