You need to install all updates, man. :| No updates is one of the major ways you get hacked/infected in the first place.
After installing the updates, my computer stopped working though. D:
What exactly is happening that is making you reinstall, anyways?
My laptop stops working. More specifically, it never reaches the Windows logo when you start it....wait, I'll have to be even more specific...
Here is how it is right now:
My laptop sometimes freezes out of nowhere (can't move mouse, no keys work, etc etc) and the only thing I can do to get it to work is by holding the power button to shut it down. Once it is off, I proceed to turn it on again, but it takes like 20 minutes for it go past the "@Microsoft" loading screen. After waiting for it to load, it turns dark (as in this is what usually happens after the loading screen, but 100x times faster), then the mouse arrow appears on the screen and appears to be waiting for the Windows logo to appear. Shortly afterwards, the screen turns into a different shade of black (as in the Windows logo is just about to appear), but then the computer crashes (blue screen of death) and the cycle repeats. Once this happens I can't go into safe mode or anything at all.
So the only option to get my computer working again is to do a clean install via Vaio's software (f10 key). I can't use the system restores because there's something wrong with the last ones made, and the first ones made have some kind of error about they already existing (I seem to have found a fix to this through google, but I've yet to try it).
I'll post some other things as I remember them lol. Guess I should go to a forum for repairs in case of a virus? (avast caught one....)
Sorry about the one-hour-late reply, I was doing a boot scan with Avast.
