Computer wont turn on

When I came back from spring break I turn my computer on and it stay on for like a secound and turn off. When I press the power on it would not turn on. Nothing works and I tried a new cord and plug it in to different outlets and still wouldn't work. Could this be the power supply. Also, if it is what power supply should I get and how many watts do I need to get. What is a AT and an ATX. Does my computer need a certain one. Thats for the help.

it sounds like the PSU, but if you can get a spare one to try first rather than buy a new one. a quality PSU can be expensive. ones i've bought were between €25-€135 ($30-$165). the vast majority of mobos are ATX, only the older ones are AT. you also have 20 and 24 pin ATX PSUs and only the very recent ones are 24 pin. so post your mobo model and some will tell you the type you want. you can also go here to calculate the size of a PSU you need.

if you are not sure what is inside your case you can download 'pc wizard' to give you a run down on whats in there.

If you have a dial up modem, try removing it and any other cards you do not need to boot. I have seen modems get knocked out by lightning keep a computer from turning on.
