If you’re not pulling our legs, back up anything you actually value NOW! Set back some money, keep real good backups starting immediately, and take inventory of your OS discs or install media...any shock to the device strong enough to cause that means you’re most likely gonna be replacing hard drives Real Soon Now.
I always back up everything important to an external drive (not that much is very important in the whole scheme of things), and have all program and operating system disks.
The screen I got had words like “crash dump” near the bottom. Near the top was something like “If you have never seen this screen before turn off and restart. (recommended)” I think the other option was to “restart normally”. So I did the “recommended”. Then it went through a repair process for about 15 minuntes, and at one point it asked if I wanted to go back to an earlier restoration point (recommended), so I selected that. After all the gyrations, it seems to be fine.
My little netbook, I just turned off (hard) and on again and it, too, seems to be fine.
I think it’s Bush’s fault.
