What age is your hard disk? Does check disk come up with bad sectors? Try Chkdsk in Recovery Console with parameters /r /p.
Yesterday I started getting a bunch of corrupt file messages while running XP pro S2. I was told to run chkdsk each time. Then the computer just started re-starting it's self over and over again. Sometimes after being on for 5 minutes sometimes 30. I re-installed windows deleting the old partions and starting from scratch with a full format. The mystery shut downs have disappeared but I have a new set of problems. I get the odd corrupt file message but I can;t seem to install ome programs. Office will not install for me. it keeps asking me to find different missing dll files which are clearly on the cd. i tried copying the files to a hard drive and pointing setup to thembut that didn't work either. i have two cd drives and it is does it on both. My power supply is fine.
Anyone have any ideas on what might be going on here.
Thanks for the help.
