Compaq Presario C700 Keeps Destroying Power Supplies?
I've had this computer for a little over a year. Around the year mark, it destroyed the power supply it came with. Then, after purchasing a new one, within a month it was destroyed. The warranty is done on my computer so thats done...Any other ideas?

You have a short on the board, or a bad card. Graphics cards can blow out different COMPONENTS if they are faulty, it could be a # of things, Since warranty is gone, if you have some spare cards, take each one out one at a time, and listen for different beep codes and then look up the beep codes at the manufacturer website under schematics. But first do your research, get all your parts together. Place the pc on a rubber matt, put on a static band or a cooper bracelet, Memory should be checked too! If you have onboard anything, the bios needs to be checked to see if a card will replace the bad circuit. Get your specs and schematics first.

Generally, when a computer is frying PSUs it means there is something environmental that is causing the problem.
It is spring after all, have there been several thunder storms recently?
Do you have an older house?
Do you smoke?
Do you have pets?
What kind of power supply did you replace it with, brand and wattage?
Do you have it on a surge protector? If so, does it have automatic voltage regulation?
Do you have other computers in the house?
Did you recently add something to the circuit? Perhaps an Air Conditioner in the same room?
