Sorry if this is in the wrong thread, but I can't seem to find a better one to put this in. As the title suggest, I'm having trouble turning my computer on. It started happening after my cooling fan just stopped working one day. I smelled something burning, and I usually hang one leg over the tower when I sit so my foot, which was near the back, was starting to feel hot. Thankfully, it wasn't my foot that was burning, and I'm not sure I actually fried anything, but I knew I had to do something. My dad told me to remove the cover to help prevent overheating, and it seemed to work a bit. But afterwards, sometimes it just wouldn't turn on. So I'd have to turn off the power strip or unplug the power cable for a few seconds, replug it, and turn it back on, which worked for a while. But now, I'm lucky if it works at all. Whenever I try the unplug method, it'll turn on for about half a second to a second and a half, and just shut down. Now I'm kind of a computer newbie, if you will, so I don't know much about BIOS and other things, but I heard your system goes through a check to make sure things are running before it turns on? Should I try replacing my cooling fan? The thing is, when I removed the cover, I noticed my fan was in this box that said not to remove the cover or something, so I forgot that idea. Also, very occasionally, my computer WILL turn on, even though the fan is broken, so I thought maybe the fan didn't have an impact. When I did get it to turn on, though, I would leave the computer on, afraid I wouldn't be able to turn it back on. Good thing I saved a backup... So I wouldn't be having a problem, except I accidentally turned off the power strip with my foot... Curse you, improper posture! Oh, by the way, my computer's kind of old... maybe seven or eight years? It's a Pentium 3, obnoxiously large, loud, etc. Horrid specs: 451 Megahertz, 18.6 GB Hard Drive space, I've had to replace the operating system three or four times due to lack of virus protection etc... I know it's time to get a new computer, but I still want to figure out how to turn it on by the time I get one and in case this happens again. Any help would be appreciated, thanks.
