Error 0x0 - its the rest of the number we need to determin the problem.
I assume you do not have a back up?
I would first back up all important data photo docs serial numbers etc,
you could try running sfc / scannow from a command prompt and hope it completes before the machine locks up.
If you have a win 7 DVD you can boot from that to do a repair / or as long as you have your windows serial key you can download and make a win & dvd or usb to boot from and make repairs or even clean install
