can't start my computer

Could be a number of things, but it most likely is something heat related. I have had this a couple of times and each time it was a blown capacitor on the motherboard.

Some of the computer problems that may arise out of this situation are as follows: 1. Memory Card 2. Processor 3. There are some virus causing the problem 4. Ste-up problem
