in my system32 folder in windows explorer i have noticed that there alot of files high-lighted in blue, including a folder called DRVSTORE also high-lighted in blue. Does this mean that important files are missing? because i have noticed my PC has not run so well lately. is it just worth wiping the whole system and reinstating everything, or is there another way?

i may have accidentally deleted some of the files when i used some virus program or something like that, not knowing what i was doing... ooops!
is there a way of finding out what may be missing and how i can fix it?

thanks

Hi They are Blue because they have been compressed by Windows to save space or there Uninstall information For Windows Service packs and such, There are usually a lot of these in your WINDOWS folder
