my pc suddenly stopped working. windows would start and get stuck on the green task bar screen and then just sit there indefinately.
i rebooted and pressed f2, and the pc started the windows memory diagnostic tool. after this i tried to start in safe mode and it crashes at 'windows\system32\drivers\crcdisk.sys'
the problem is, i got the pc from work as a refurbished unit and was not given a vista disc, so can not do a windows repair via cd. how can i get the pc to start as normal again?
