I was playing a racing game with all of a sudden my computer rebooted. I rebooted and then when I tried to run the any program the not less than or equal to blue screen would pop up for just a second. Now when i try to boot is says that ntfs.sys is not there and to use the repair tool. Unfortunately the repair tool is messed up too. I booted to a dos disk but the windows folder does not show up on the c: drive when I do a dir. Does this have anything to do with the fact that it is a ntfs file system? I am running winxp and it has been fine for 6 months. I have a ibm hd but i used the utility and it said it was fine. What should I do and what do you think? Thanks!!!
