I've really had problems with my computer over the last month. My ISP has been kicking me off-line every 30 minutes (AOL dial-up. Yea, I know already....) and I've been getting annoying McAfee pop-up boxes every time I start-up the computer. Also, Windows seems to be corrupted because I can't even shut-down the computer reliably (I often need to depress the power button to shut the damned thing off). Anyways. I've spent literally 10 hours on the phone with Dell & AOL over the last month. Dell even came out, and replaced my modem under warranty (as it turns out...I think they replaced a perfectly serviceable modem) because they didn't know what else to do. During my last call to Dell, the technician had me do a "system restore". During the restore process, he explained to me that the hard-drive would be returned to the way it was when it was shipped to me new. Indeed, as promised, it seems that my computer now performs the way it did when it was new! Have I really rid myself of all of the viruses, spyware, worms, and adware that easily? I'm thinking I should do a system refresh every 90 days, just to keep things running smoothly. I don't keep much on my computers in the way of files, and don't load much software (Turbo Tax is about it). I can easily save those to a CD before refreshing the computer. Am I missing something?
