I have an older Gateway computer. Last night I turned it off and it was working fine before that. But when I went to turn it on this morning, the indication light on the POWER buton turned orange and the computer wouldn't start. Any ideas/suggestions on how to fix it? COULD be any number of things, but assuming it's a desktop the most obvious first thought is the power supplyI tried changing out the power cords and replugging everything in. None of that helped. Anything else power supply rated or other ideas?The POWER SUPPLY UNITWhat do you mean by power supply? And what should I do? Sorry if I seem clueless. I'm 15 years old and I don't know much about computers. I'm not technologically challenged I know how to get around. But I suck and troubleshooting.http://en.wikipedia.org/wiki/Power_supply_unit_%28computer%29

So basically I have to take it to someone who knows how to fix computers.
-try start the computer, with NOTHING connected, except for the CPU, power, power button, and monitor
 -got a NEW BATTERY for the motherboard to ELIMINATE that as part of the problem.The likelihood of it being the battery is slim, but it's easy enough to replace so you might as well give it a try. As for the power supply, it's easy enough to do yourself.Ok you guys have been alot of help. By unplug everything do you mean everything inthe innerworkings as well or just all of the external hardware plugged into the back.You can disregard that part of the advice. You don't need to disconnect everything. Just replace the battery and if that doesn't do it try a new power supply.Ok thanks. And the battey is the one thats like a bigger watch batter right?
Correct. Just be sure to pull the power plug before messing around inside the computer. And don't worry - it's hard to do any damage to anything other than the ram (be sure to touch a piece of metal before touching ram).Ok thank youYou're welcome. Be sure to post back with any additional questions or to let us know how things worked out. Oh - and power supplies fail all the time, it's really no big deal if that is indeed the problem.
