We have 6 years experience with computer tech support. We have yet to find a problem we couldn't fix. We garauntee your computer will come back error free and running smooth. Well, as smooth as a Microsoft machine can run. On rare occasions, the hard drive may have to be erased, and your files lost. We are warning you now, and will warn you once more before we begin work. We will not be held responsible for any data loss that may occur. Erasing everything is a last resort, and we will attempt to contact you to let you know first. We can attempt to back up your data first for a fee. You will not be charged this fee if the backup is not successful.
