Could also be that the PSU isn't powerful enough. What do you have in this machine?

650W should be more than enough.

Then lets go back to basics. Take the motherboard out of the case and place it on an non-conductive surface. Plug in the CPU (with the HSF, of course), RAM and PSU, and try to start it. If it start the plug in the graphics card and a monitor and try again.

With the board out of the case, and only the CPU and ram installed it still shuts down. Do you get any post Codes or does the computer even get past post if not I would try the CPU and RAM in a different computer and see which one is faulty. You may also have a bad motherboard.

CPU or motherboard sounds like more likely suspects all the time. There is one other option: that the CPU is overheating and thus shutting the computer down. You have the HSF mounted properly with a thermal pad/paste?

Along with Alpha's post, If you have your heat sink and fan properly installed, try booting the computer with just the CPU installed it should Post and fail due to the memory not being installed, If you can get it to post without the ram you may have a bad ram chip ( this is an unlikely suspect since if the ram was bad the computer "should" still post I have seen stranger things happen though ). If it still doesn't post try without the CPU and with the ram installed. This is a shot in the dark as I have never tried to POST a computer without ram or a CPU installed. Also If I remember correctly a dead CMOS battery caused trouble with a members computer before check the battery and make sure its still good.

This sounds like what happened to me. I have a AMD/ASUS system with OCZ DDR2 RAM. After coming back from vaction, it started doing the same thing. What I found out was that AMD/ASUS had this problem the most, but some Gigabytes suffered too.

Try this. The most common cure is to remove most of your memory and try to boot your system off a single RAM module. If it doesn't boot, swap the RAM modules and try again until it boots. if it doesn't, I can't help you from this point.

If it boots, restart and get into the BIOS and make sure you had the original settings. If you are running OCZ 1gb modules you may want to up the DDR2 voltage to 2.2v before you install the second module. Shut it down and add the next RAM module and then boot up again. Keep doing this until it fails in POST or you have all your memory modules reinstalled.

I am assuming you have tried all the reccomendations Your best option would be to take the components to a computer shop and see if they can test them to see which one is bad otherwise you may replace a part that inst bad. 3 possible outcomes they find nothing wrong (which is highly unlikely) they find one part bad and you replace it, or they find out there all dead.
