Hey everyone,

So I'm at a quandry. We are having problems getting are computer to boot up. It will start, but much of the time it just gets the fans going and the CD and DVD ROMs but nothing esle. We have to do a hard restart several times before its actually boots.

I thought it would be a power supply problem. So I went out an purchased a new one. Well that not working. Still the same problem.

Anyone got any bright ideas of what the problem is.

Once its actually started and going, everything runs just fine.
 
To check your amperage of the PSU, look on the side of it, there should be a chart with voltages 12V, 5V, 3.3V, etc Give us the Volt and the amp under it. We mainly need the 12V amperage.

Its a 12V as well as the first one was. The one before was a 350W and I purchased a 450 this time.

That's not the amperage. Your 12v has an amperage, so it should look like "12v 18A" where "18A" is 18 Amps. The higher the amps the better, iff you've only got 10A on your 12v line that might be a problem.

Could also be a motherboard problem. Can you try the PSU in another machine and see if it boots it up. If the PSU works in other computers it's not faulty and you can move on to checking other hardware from there.

Remove all unnecessary hardware from the computer to try and isolate the problem. Unplug case fans, remove expansions PCI cards, try running with just 1 stick of RAM, unplug CD-Drive. If it still doesn't boot its most likely motherboard.
