How can i recover my installed programs, my old user account?

I inserted a usb disk drive on my laptop. I tried to copy an AutoCAD file drawn by some Japanese client of ours (in Japanese font). Then I reboot, and suddenly, it kind of reformatted itself and deleted my old user account. All files are still intact but most of the programs doesn't work anymore. I tried to use system restore but all restore points were gone.
