Ok well my brothers friend has left a computer in our garage over the entire summer until now. bascially i think he will never take it back. So i decide to use it. I notice it says pentium 4 and it has a cd rw drive, and a dvd rom drive. Im thinking sweet! cause i need a burner. Anyways i hook it up and the damn thing will not turn on. I open up the computer and look at it... it is real dusty and that is about it. The mother board light turns on and off but the computer wont turn on. Is this a power supply problem? is the whole computer fried from sitting in my garage from houston heat? what do yall think?
