Don`t sling arrows my way or I`ll reroute them to my daughter....
She has (or had) a Compaq Presario desktop. A "P4GV-LA" motherboard. She had plugged a laptop into a usb port out of curiousity....I know....I know....Now the problem and what is fried:
When I plug the desktop pc into the electrical receptacle, both fans are automatically running just as if I pushed the "on" button. It powers up no doubt, but nothing happens, no monitor activity or boot up. The green light in the back of the unit is on, but the green light in front that used to come on when the desktop pc was turned on is not on now. I went by the specs and reset the bios, etc. Is the motherboard gone on to greener pastures or might there be something else I should look at. I`m not a tech, but I do know my way around inside of a pc a fair amount.
 
Probably fried... I'd pull any connections from the PSU off the board, unplug it from the wall and let it sit for a while. I once did short out a computer and after it sat for a few minutes, it began to work again.
 
Laptop to Desktop? Never heard of that before.. Its probably fried. No beeps ? I would just salvage what you can and get another computer. Or build another computer outta the salavged parts. We're here to help!
 
Yeah, it wasn`t the best idea in the world to be curious at that point. I`m thinking the mb probably died, couldn`t figure out why the fans started running when she plugged it in. The on button is dead. Thanks for the replies!
 
How did she connect the laptop to the desktop? What type of cable did she use? The USB cables I have would not be able to physically do this because of the ends.
 
They used an USB data transfer cable. I have one on my USB External drive, its pretty old... both sides of the USB cables are the same, and can plug into a usb port.
