Hello! I'm hoping you can help me with these 3 problems I have with my computer! [I'm not that computer literate, you know. And there's something wrong with my camera, it can't seem to focus or something.] 1. Won't Start Unless Screwed Sometimes, my computer won't start up. It freezes at the opening screen or the monitor acts like it can't turn on, or something. However, if I open up the CPU and air it out for a bit, everything works when I plug everything back in. I'm sick and tired of having to screw open the CPU when I want to turn the computer on! Help please! As you can see, it's pretty outdated. Bought this XP about 5-6 years ago. 2. Buncha Colored Wires In front of my computer, there's a couple of usb ports and some audio ports. They don't work, because the wires that connect them to the computer end in a sparkler-like bunch. I have no idea how to plug them in. Sorry about the blurryness. My camera is like that... 3. Filthy Fan On my motherboard there's this fan. It is absolutely FILTHY! One light touch and my finger's dust-covered. I need to take it off and clean it, but I have no idea now. Poking a rag between the blades don't help either. Already tried flipping the white thingys at the end, too.. Help please techies! Other tips welcome!
