Ok, I buit a computer for someone, and just two days ago I install a new zalman cpu cooler for them, after the PC worked just fine. So today I look at my email and they say that they put the computer to sleep, and when it came back it said there was an error with explore.exe. They had to shut it down, and now it wont boot! This is what we have tired: -Safe mode (wont boot) -Every other recover mode!!!! -XP cd go to recovery (wont work) -Called microsoft - THEY CANT HELP!!!! So if you have any things to help me that would be so great!!!! I can reinstall windows, but I really dont want to.
