For a week or so, my computer had been locking up when I would leave it idle for more than a couple hours. If I turned it off and let it sit for a while, it would start right back up. Although I never saw any warnings, I'm pretty sure it was just overheating.

A few days ago, it stopped booting up at all. I cleaned out all the vents and the interior of the case with air, but that did not solve the problem.

At first when I tried turning it on, the fans would start running and the blue power indicator would light up, but nothing else would happen. Blank monitor. Now the power indicator light has stopped coming on as well.

I know nothing about hardware and decided to check here before messing around with anything. Have I burned out the power supply or the motherboard by waiting too long to give it a good cleaning?

Hi and welcome to TSF you could take the side of and check all the cables and connections are firmly and correctly seated,do the same with the ram and videocard,then check the heatsink and fan sits on top of the cpu,get a can of compressed air and blow out all the dust and debris from the heatsink and fan and the airvents and case be carefull around the fan use a straw or similar to prevent the fan turning and remember safety first so switch off and unplug the power from the computer and ground yourself either with a wrist strap or by touching the bare unpainted part of the case,is this your machine Gateway Support - Specifications upgrading the power supply should be a priority a minimum 550w or better,A good known brand you can find info on many here http://www.techsupportforum.com/forums/f210/power-supply-information-and-selection-192217.html
