So here's the story. Was working on the computer for 1/2 hour and then proceeded with shutdown. As it's getting to the last step in the process it starts making a ticking sound and then I smell something is burning, so i shut off the power. I open the case and see the power supply is burnt. So I replace it with a Dynex 350W. I see the green light on the motherboard (ASUS P4PE) turns on and it didn't before. I try turning the PC on but with no luck. So I look at the pentuim chip and see its fried. So i get a replacement chip from Intel (P4 2.2GHZ) and install it. Again the computer doesn't start. I really dont know what the problem can be. What's the easiset way of troubleshooting? Can the mobo be dead although the green light turns on? Can it be the power button on the case that got fried and it's not starting up the mobo? Please help!!!!!!!!!!!!! :hotbounce
