My computer started loosing its C drive and would reboot and ask that an OS or emergency startup disk be put into d drive. I did the latter and the system began to start setup but after a few seconds jumps to a black screen and video mode not supported comes up and moves around. then it reboots again and the windowsxp screen comes up and tries to re start setup and fall back to vedio mode not supported. I have tried safe mode, C:\>scanreg /restore and get a bad command or file name. Any ideas

video mode not supported is probably a message from your monitor, not your operating system. Some monitors may display that message when the monitor is on but not connecteed to a video port, or when the computer isn't producing any video. Or it may display the message if the video settings in Windows are not supported by the monitor. Try booting to the menu Safe Mode is on, but choose Enable VGA mode, NOT Safe Mode. That loads Windows normally except it forces the video into a bsic VGA mode all monitors and video display adapters support. If that doesn't work, Check your hard drive with the manufacturer's diagnostics. See the latter part of response 1 in this: http://www.computing.net/windows95/... If you don't have a floppy drive, you can get a CD image diagnostic utility from most hard drive manufacturer's web sites, but obviously you would need to make a burned CD, preferably a CD-R for best compatibilty, on another computer if you need to. AND Failing power supplies are common and can cause your symptoms. E.g. They can certainly cause unexplained rebooting. Check your PS. See response 4 in this: http://www.computing.net/hardware/w...

Your best bet is to boot from your XP CD and load the recovery console. Then run 'chkdsk /p' from the console. If any errors are not fixable you should look at backing up any data you wish to salvage and replacing the hard disk. Let chkdsk finish, if the drive is in rough shape it could take several hours to complete. J. j e r u v y a t y a h o o d o t c o m
