Power Supply

Today I was just surfing the web and my Shuttle SN25P just turned off. My power supple does not smell burnt, so i dont know what can be the cause of this. When i try to power up my computer it turns on for like a split second then back off. Please email me with any help or answers you can help me with. Thanks Alot, Jose Torres

 

Looks like you're going to have to buy a new psu, but check all cables inside first, particularly the 20pin cable from your psu to motherboard.

 

If you have a way to test the PSU, I would do that before anything else, just to make sure that it is indeed the PSU. you can either try a known good PSU or if you are adventurous, you can use a piece of wire to jump the Green & Black wires on the ATX to see if it will power up.

Here is a good tutorial on how to do this. You can buy a part made for this, but a piece of wire works just dandy.

Also clean out all the dust bunnies from inside the case.
