My PC was working fine one minute, then it suddenly froze. I turned it off, and when I turned it on, it wouldn't boot. It gets to the XP loading screen, then reboots suddenly and gives me the "Windows did not start successfully" message. I tried safe mode, but it did the same thing before it booted (hung as MUP.SYS was loading). Even after unplugging all PCI cards, peripherals, etc. (not the keyboard), nothing works.
A couple of hours later, EXACTLY THE SAME thing happened to another PC; this time, a brand new laptop.
Both run Windows XP SP2, both connect wirelessly to the same modem/router, and neither of them have ever shared files.
Help! What now?
