Check the capacitors on the motherboard (the cylindrical can like objects) - have any of them bulged outwards or leaked? They should have flat tops, but if they go bad, the tops bulge outwards.

May have a bad power supply (just because it passed the power test doesn't mean the PSU isn't faulty).

I checked the power cord by plugging it in on a backup and it ran fine also checked to see if it was set to the right voltage and thats not the problem.

No, I mean the Power supply unit, the actual box you plug the power cord into - a box that converts high voltage mains electricity (110, 220 or 230V depending on where you live) into low voltage DC that PC components use (12V, 5V and 3.3V)

Definitely a PSU-related problem.
It sounds like your not getting enough voltage into your PC, are you sure your PSU is set to the correct voltage?
Check on the back of your PC for a voltage switch and see what it says.
Or.. one of the power cables to your motherboard might be loose. Make sure the power cables from your Power Supply running to your motherboard are firmly in place.

sammorris how do I check to see if the power supply unit is bad. And I have already checked the voltage and that is correct.
Why would my computer just stop with the screen showing the last images with nothing responding?

You can plug in another PSU from a different computer. I would not recommend putting this PSU in another PC to check though, it might fry that one too.

Nah, I doubt it. Not unless that PSU was lower in wattage than the old one, or a cheap nasty unit.

Any other way besides a spare psu which I don't have. Could it be tested by a amp/voltage tester. If you are wondering I am working on pathetic laptop right now.

I just realised we still haven't ascertained what brand of PSU your using. You can tell quite a lot from brand alone when it comes to PSU's, especially if your having problems with it...
Open up your PC, have a look at your PSU casing, should be a sticker or something on the side that says the brand and model.

The power supply unit is a Newton Model NPS-160CB-1 A. It also says on the sticker output 160w min. By the way there is a sticker with 6500582 below the info

Your power supply is rated at 480W and Newton is a decent enough brand, but without testing another PSU in your PC there's really no way to tell if it's busted or not.
Your going to have to get your hands on another PSU it seems.
