Ok it sounds as if ya Power Supply Unit (PSU) may have gone faulty. Generally when a PC won't turn on it can only be caused by a few things. a faulty PSU, a faulty component/card stopping the PSU from working, Motherboard Fault. Faulty RAM
Ya have to isolate which one. So first open ya case up, then take note of the way things are connected. (Write them down, draw a picture) Then unplug ya Hard Drive, try it, & then ya CD/DVD & try it, take any add on cards out, try it... & so on... to isolate ya faulty bit.
If it still doesn't go after removing everything except the Motherboard, then ya gonna have to try another Know Good PSU.... of course if it doesn't work then, ya have a MotherBoard fault.
Just work thru it slowly.. and ya be all good.
