Hello, My Windows had shut down and would not start back up. When I started my computer, it gave me the following STOP ERROR: A problem has been detected and windows has been shut down to prevent damage to your computer. If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps. Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check you hard drive to make sure it is properly configured and terminated. Run CHKDSK /F to check for hard drive corruption and then restart your computer. Technical information:xxx STOP: OXOOOOOO7B (OXF9E7264O,OXCOOOOO34,OXOOOOOOOO,OXOOOOOOOO) I found a thread on this website that advised I do the following: howard_hopkinso 04-27-2006, 03:42 PM You need to do the following. 1 restart your computer and go to setup(bios) usually by pressing the F2 or delete key. 2 Once you get into setup look for the boot menu and make sure you set it to boot from cd first followed by your hard drive. 3 Put the Windows xp disk into your cd drive. 4 Now save your settings and exit bios. 5 While your computer is booting you will see a message that says "press any key to boot from cd" press any key. 6 When the welcome to setup screen appears press enter and then press F8 to accept the Microsoft licence agreement. 7 You will be prompted to repair an insallation press the escape key. 8 Now select partition that you want to reformat and press the D key to delete it you will be asked to confirm that you want to delete the partition. 9 Now press C to create a brand new partition you will be asked what size you want the partition to be in mega bytes. If you just press enter then the partition will be the maximum size that you can have. This is perfectly ok if you don`t want to create multiple partitions. 10 You will now be asked to format the partition select the ntfs file sytem and do a full format. 11 Once the format is complete setup will continue. Your computer will restart during the remaining setup again you will be asked to press any key to boot from cd DO NOT PRESS ANYTHING. and setup will continue. Once the setup is complete and you are back in Windows remove the Windows cd from your cd drive. Regards Howard I did the above and NOW ALL OF MY FILES ARE GONE. I am very very sad, as I had no backup and it was at least 6 years of my life - files, photos, videos...all of which I assume is gone forever? I am not good with computers, but figured I could fix via instrucitons...guess not. ANY HELP? IS THERE ANY WAY TO RETRIEVE MY FILES? Thanks for your time.
