    I inadvertantly fried my motherboard by plugging a usb device into a usb port upside down. (the little white piece had fallen out of the usb port which allows usb cables to plugged in only one way). My question is - if a motherboard shorts out does that mean that my processor, sound card, etc are also toast? I will replace just the motherboard if that is all that is bad, but if I have to replace the processor, sound card, etc then I might as well buy a new pc. Is there any way to test the processors and sound cards to see if they still work? Thanks for your help in advance.

    Yes, the power supply comes on, the harddrives spin, the fans all work including the cooling fan on the processor chip. I'm just assuming that the motherboard is bad because it can't even boot the bios screen. When I took the cover off, I noticed that the cord from the usb port had literally melted but I visually see no other damage.

    In this statement I ASSUME you are talking about the line from the motherboard USB header to the front panel ports. If so, have you disconnected that line from the motherboard header to see what happens?

    Yes, it is the line from the motherboard USB header to the front panel ports and I disconnected it and it still won't boot up.

    Although this would appear to be a motherboard problem, I would start by having the power supply tested. The dead short on the board could have knocked out the +5v rail on the power supply.
