Well thats good.
Lets try this . I have ran it fine without the Xp cd but it doesnt work for everyone.
Click Start
Select Run
At the prompt type sfc /scannow Please note that there is a single space between sfc and /scannow.
Typing this will start the program, and a box should appear telling you how much longer the process should take.
Sometimes the scan will prompt you for your Windows XP disc upon starting the scan. if this happens please make sure that you can view protected files:
My Computer
Tools
Folder Options
View
"Uncheck" Hide protected operating system files.
Then rerun the scan. If this still asks you to put in your windows XP CD, and you do not have the CD (If you bought it preinstalled) post back for more tips,
Once the scan is complete:
Please reboot, and let me know if anything has changed
