Sounds to me it is most likely your RAM or memory. If it comes loose nothing will happen, try reseating everything in your computer and then try it. If that doesn't work then I'd try a different power supply because if it was your CPU, motherboard, etc you'd get some indication from LED lights, POST beeps, or something appearing on your monitor with an error message.

This is where things get very complex and if you don't do this for a living or are an avid computer person I'd just pay someone else or buy a new one.

If the working power supply didn't fix it, I'd build the computer outside of the case because grounding within the case can make it do funky things, I'd use a screw driver to turn it on by touching it between the prongs that are responsible for your power switch. Just remove the jumper and use a screw driver to connect the two prongs. That should turn your computer on outside the case. Refer to the writing on your motherboard or your motherboard manual for that information. If that does not work then I'd put my memory and hdd in a working pc and run diag. tests on them and boot from a CD on the bad PC with Ultimate Boot, Hiren's or something along those lines. I'd disconnect all unnecessary component, such as network cards, video cards if you have on board video, etc. I'd try putting memory in different slots as well. I'd then replace the CPU and heatsink/fan, their usually stable and rarely die unless the heatsink wasn't properly installed or you overclock your CPU. If none of this worked, I'd have to look at it myself and I'd figure it out and you'd pay me to do it because this is what I do for a living,hah. Anyways That's a brief and basic run down of what I'd do, considering the machine is worth it. If the machine is old as crap, I'd take the hard drive out and put it in a working computer. Trash the rest. Run a diag test on the hard drive, if it passed take the stuff I need on it off, if it failed Id use NTFS GetBack or some other various software to recover as much as I could off it, and sometimes their just completely dead at which point your outta luck.

I know Im an outsider and Im here because Im looking for a translation to a song by the Bothy Band, well actually any and all but one in particular. "Is Trua Nach Bhƒuil Mé in Éirinn (click for thread)" is the song. If I could get an English translation of the lyrics I'd be extremely grateful. You can send me the translation(s) to my email, e21flesh@hotmail.com Thank you again very much for your help. Also in return if you have any PC troubles I'd be glad to return the favor with some technical advice and cheap places online to get good parts.
