    A friend of mine(and i really do mean a friend) brought me his computer. He discribed a problem yesterday, and I kinda helped. His computer was shutting down after 30sec -2 min of operation. Turns out is CPU fan was not on, and it was overheating. Now he has a new fan, but the computer won't power up. The red LED on the Mobo lights up, and all the fans turn when he tries to power up. However, the front LED's won't light up, and the DVD-Rom won't open. I am confused. His the power source bad, i don't see how the mobo would effect the dvd-rom from opening, it seems as if it's not getting power. Also the HDD is not turning, even if the board and CPU were fried it would still turn wouldn't it?? Any help anyone can provide i would greatly appreciate it. Thanks for your help.

    Ok, i have more info. I pulled the fan off, and the processor is a AMD XP 2000, 1.6 G/hrz. Slot A, I looked at the processor and there is discolorization(sp?) on the top and bottom of the chip around the portion that touches the heat sink. I assume the CPU us bad, any ideas on the MoBo???

    If you think it is the power supply Compusa sells a power supply tester for $25. see if yours is a 20 or 24 pin.
    The mainboard controlls the power supply, right ? the on/off switch plugs into the mainboard.
    So even though it was overheating, it worked for sometime, now it will not. If the mainboard was going to die it would have done it a long time ago. I think something is disconnected or the power supply went bad.
    i would disconnect everything not needed to POST, disconnect the HD,FLOPPY ...etc
    reseat the vidoe card and ram. make sure the A/C is unplugged

    I don't know if it's a bad cpu but definitely a motherboard shot.

    Ok, i checked the IDE cables they are all ok. I tried unplugging everything, and starting it up, and nothing new happened. The fans turn, and red light on the Mobo. The HHD isn't spinning, and the DVD-rom won't open. I thinking this has to be at least PSU issues, as the MoBo shouldn't effect either of these things. I am work work, so i don't have alot of options. I will pick up the tester on my way home. i have to agree, i go to compusa, so i can get one today. I ordered a new CPU, i figured the black on the chip couldn't of been good. I just don't want to have to replace the Mobo, if i don't have to. Of course, i realize the for $120 i could get a new CPU, MoBo and PSU from Newegg.com or Ebay. This may the route i end of going. Thanks for any and all help, in advance.

    Discolouration on the bottom of the processor?
    Sounds like they may have fried their CPU also.
    Athlon XPs are about the easiest processors to kill in my experience......

    (EDIT: Okay I was a bit late!)

    LOL all the power connectors go back to the same place in the power supply. The 5v go back to the same bus, the 12v same bus....etc. So if you test the mainboard connector you test it all. THAT IS TOO GIMICY for me.

    Here is mine. I didn't buy it for testing a PSU but it works all the way down to testing max amps. ;)

    That would be pretty useless for testing PC power supplies anyway. ;)

    Yeah, I know. It reads them fairly well. At least the voltages it does really well. I have never tried to amp a PSU with it. I may try it to see what happens some day when I am bored. I'll wrap it around a yellow and see what it reads. :D
