    Boot up failure

    There are many reasons that could cause this problem. It could be a faulty power switch, solution, find where the power switch connects to your motherboard and trip the two pins with a screwdriver. Your motherboard could be grounding out somewhere. In that case you can take everything out of your computer, set it all up outside the case and try it then. It could be the motherboard which means you would have to replace it. Try those things and get back to me if it still does not turn on.

    Could you give me more indepth specs on your computer or even a picture of the motherboard. I think that would help solve the problem, but for now if you can get a hold of another motherboard that is compatible with you system then test all of your parts seperatly on it or you can take everything off the motherboard and just leave the atx power connected and try to turn it on like that which will narrow the source of your problem down to either the mobo or the PSU.

    This is another persons computer. It is a gigabyte board with an amd 2800+ and 512mb ram. It is about 1 year old and she said she was working on the computer when she smelled smoke from the computer. She turned it off and then later when she went to turn it back on again it did not have any power at all. No nothing. No fans. No leds, no nothing. I have the board out to check for possible shorting out on the case but nothing still after that. I checked all connections and all are secure. I bought a new psu and nothing either. I'm not saying it's not the psu but it is sure must be more than that also.


    She didn't actually see any just smelled burnt after I talked to her again. Doesn't really matter it still doesn't work. They are all under warranty.

    Smoke? lol. I can't imagine why you wouldn't include this bit of information up front. Have you tried to track down the source of the smoke? Were you able to determine what it was?

    PSU/MOBO/CPU fried

    I would not assume that all of the these components are fried becuase anything could have happened. When i had this problem it was the PSU but since you already replaced that it cant be that. So my next step would be just connecting the mobo and the PSU, to elimnate the possibility of anything but the PSU and mobo if it does not turn on. Also you should check all of your jumper settings. On certain mobos if you have the CMOS jumper set to restart it, then it wont work because it cant load the POST. If you are still looking for the power, reset, ect... they should be at the bottom right corner of the mobo if it is in the case. There should be a reletivley large section of pins with colorful cords coming out of them and it should all be labled in some way.

    After a little disecting I looked inside the psu and wow. All burnt up. So that is one thing that was bad. I am waiting on another psu that will be here Monday and go through all the steps to check all other components.
