Hey guys, I'm running a AMD Barton 2500 XP with 768 MB of RAM and I am having problems shutting down my PC. The problem is that when I shut down the PC, the CPU fan, Case fan, and Rear fan does not turn off, everything else is shut besides those. When I turn off the power switch behind the power supply, the PC will turn off, but when I turn on the PW supply switch the PC turns on automatically. I figure it must be power supply problem, since i'm running a 350W or motherboard.
