Technical Support

I once vacuumed mine, and now I have to use a different one. Where are the power settings? I only know about them in the display properties. The computer was turned off for a while, it cooled down, and so far there haven't been any glitches (except for the multicolored numbers or something). Yes, it's probably just the video card overheating. Added after 4 minutes: 1. I won't do that for now. 2. No. 3. I don't feel like it, maybe later. 4. Yes, I thought about that, but maybe I can just reinstall them. 5. Everything is fine. 6. I have Kaspersky installed, I checked it, although not completely. (I found one virus, but the glitches continued.) 7. I wrote about it above. 8. I don't think I need to clean it, and I don't want to do it again after the last time. 9. Pfft.
