Hello, I have to admit I'm quite the beginner towards help online sites. Sadly, my computer's warranty recently ran out, and it seems like my computer was waiting to give me problems right afterwards. I'm not sure if the problem is a virus nobody's found before, or if it's a hardware problem, but my computer will randomly begin to freeze every now and then (mainly when on the desktop or surfing the web. For some reason, it's never done it during a game yet). Sometimes, it corrects itself after around 2-20 seconds, and other times I have to do a hard turn-off of my computer by holding the power switch. Sometimes, the freeze is immediate, and other times I still can move my mouse cursor around, but can't click anything or use ctrl+alt+delete or alt F4. If I do click anything, after a few clicks the computer will freeze completely. I reinstalled my computer's operating system not long after the problems began, and it did not seem to affect the freezes, but I do not believe I did a perfect factory setting restore due to the fact that afterwards, some links on firefox were still a different color, as though I had already clicked the links despite the fact that my computer had just been restored.
Also, for some reason, after the hard shut-off of the computer, my computer's clock will be set back an hour about half of the time I've done the hard restarts - quite a seemingly random occurrence.
I run Windows 7, and an Asus g75V. I know that I'm supposed to give some additional information, but I'm not quite sure what information in particular you would care to help me with.
