Remember when your new PC ran at lightning speed?  It was able to quickly download large files and run several applications at the same time.  It seemed to breeze through e-mails, even with other large applications running in the background.  Remember those days?  What the heck happened?   Is that same PC now running so slow it crashes when you try to open several applications simultaneously?  Does it take long periods of time to complete simple tasks?  Do you have error codes popping up, or are you receiving system warnings when you boot up?  Are you starting to worry about losing your files, and valuable data?  Sounds like an expensive fix, doesn't it? Well, not so fast…
