First time here and a total idiot about all things related to the inside of a computer, BUT I believe that my kids emachine has a bad power supply. There is A/C current to the cord where it plugs into the machine and the power switch on the front of the computer appears to be OK after testing for continuity with a multimeter. The problem is nothing happens when you try to turn on the machine.No lights, no noise , no anything.
Are there any fuses in there that might be blown?
How can I test the power supply? It is a Bestec ATX-250-12E model in an Emachines computer.Anything else that might cause this problem that anyone can think of?

Note that 'some' OEM manufacturers use non standard power supply/motherboards. It would probably be a good idea to check with Emachines to see wether they do or not.
Do yourself a favor BACKUP!!!

:| sorry all you mean OLD folks...Just kiddin i was burning a copy of XP Pro and got a error so i was going to fix it but then my other program i was installing said i need to reboot so i quickly replied to this so spellings off, What i was trying to say was one night my dad made me stay up with him REALLY LATE (thats usual) he always told me im the programmer and hes the electrition, anyways i was saying we used car lights for the tester, well we were burning in actualy but it still works for testing, you hook the light up car light are big watts so yo hook it up and turn the switch on on the back of the power supply and then depending on your power suplly you need the push the swich in or it will just go and if you get light your fine. Sorry guys

A late post, but a post nonetheless.
Quick and easy way to check for a defective power supply is to test the 5V standby voltage on the mobo connector. (Its usually the purple wire)In relation to this particular power supply
(if its anything like the Bestec ATX-250-12Z out of an HP):
YES there is a fuse that can be blown. It sits upright between the Inductors and 120/240V in. Its wrapped in a black sheathing, labled F1. Just remove said sheething and voila, you can tell if its your fuse or something else.
