Hi, this is my first question, but here it goes. My gateway PC recently started freezing after about 5 minutes of being on. This went on for about a week and then one day I turned it on, it froze, I turned it off, and it didn’t boot it. The light on the front of the case just stayed yellow instead of the normal green. I opened it up and found out the fan on the video card stopped working, so I replaced it with a card I know works, but that didn’t help (I imagine the video card caused the initial freezing, though). Right now, all the fans are working and I’ve disconnected the CD drive and floppy drive and taken out all the cards except the video card and I still only get the yellow light. I’ve also disconnected each of the two harddrives, which did nothing. Also, I saw some answers to other questions saying the rest switch might be stuck: if that could be the case, where is it? (The only power button is the kind where if you hit it once when the PC is on it shuts down, and cuts off power if you hold it for five seconds). Thanks for any help you can offer!
