Do you have your windows XP CD? If you do, I want you to put it in and turn on your computer. When you are given the message press any key to boot from cd..., press a key and Windows Setup will start. At the first screen where you have to enter input, hit R to enter the Recovery Console. Then you will have to hit 1 to log into your windows installation and then just hit Enter for the Administrator password because it is normally blank unless you changed it. Once you are at the command prompt C:\WINDOWS I want you to type chkdsk /p /r. This will run a VERY THOROUGH check of both your hard drive and also your windows installation files and replace any that are missing/corrupt. Once it's done, type Exit and take out your Windows XP cd. Your computer will reboot itself.
I do have my disk and I did as suggested up to the point to type chkdsk /p /r. I am only able to type c. It dosent allow for me to type more.?
