So I left my computer on during a thunderstorm like an idiot, and now after a power supply surge it is freezing like crazy. It is basically unusable at this point. It boots up fine but after a few minutes everything starts freezing. Is there anything I can do?

I had an asus motherboard that displayed that message in a similar situation, and it turned out that the surge had fried the a stick of memory, a graphics card, the psu, and the motherboard. Before replacing it, I would suggest carefully checking that the power supply still works before doing anything else (there's tutorials elsewhere on the internet), because every time you start up with a faulty power supply, the more stress you put on the components, and the more of them you could lose. After making sure that you have a working psu, since it is possible that any number of other components could be causing the problem, you could try removing components one by one (pci cards, hard drive, memory, ect.), try to boot into the BIOS, and...

Depending on your luck:
- your PSU got damaged and the computer is freezing due to dirty voltage outputs
- a surge found a path through some of your PC's components (everything connected to something other than your PC for signals or power is a potential suspect) and damaged something
- or as Giorgos said, the unexpected shutdown may have scrambled some files

If you get down to the processor and it still doesn't work, you'll want to replace the motherboard and try again.
