My computer was running sp1, which worked fine... But to download a lot of stuff, like the GIMP and my new printer software, I need sp2 or sp3... Both of these make my screen go fuzzy and dotty right after the installation. Is it a memory problem or a video card issue? I'm pretty noob at hardware stuff, so any guidance will be appreciated, and if you need to know some specs, tell me what, i'm not sure what you'd need.[b]
