Ok.. yesterday my desktop blew a power supply.
So I replaced it. The computer is about 3 years old so I figured time to replace power supply. The new one blew in about 20 minutes. So, I actually investigate and see that my cpu fan has locked up, overheating and causing the power supply to pop. So I replace fan and replace power supply again. Now the computer won't come on.. it powers for about 2 seconds then shuts down and a red light appears on the motherboard. It stays lit for several seconds in which time the comp won't do anything. When the red light goes off I can power it back on for a couple of seconds before it shuts down again.
Can you get a power supply too powerful for an older motherboard? The old power supply was 300wts. The new one is 550.
Motherboard is an Nvidia Nforce2. Red light coming on is at the D30 position. I can't find my manual to look it up...
