I know this title looks like it has a obvious answer, but I cannot figure out what is happening here.
Motherbaord: Abit Kn8 SLI
Processor: AMD 3500+ venice core
Memory: Ultra DDR 400 512 mb (two sticks)
Video Card: GForce 6600
hard drive; Not installed
OS Not installed
PSU: Enermax Noise Taker 450 Watt
There are no other drives or other devices connected.
Computer will boot fine. But when I push the power button on the case, it goes into a sleep mode of some kind. It will not shut down no matter how long I hold the power button, and will not reboot. I can only shut it down by using the switch on the power supply or pulling the plug.
Instant off. Button only. all WAKE features disabled either in BIOS or with jumper settings.
I have tested the memory, CPU, three different power supplies; I pulled a switch from a working case and connected it to the mother board, all with the same problem. It will not shut down. This problem exists with and WITHOUT an OS installed.
I have tried swapping another vid card. Still no shutdown.
All power connections and switch, LED, connections have been checked multiple times.
This problem has occured with two boards, my current one is an RMA board from Abit. I returned the prior board for the same problem.
The only thing I have not done is flash the BIOS
I'm at the point of using the board as a Bass lure, or pouring beer in the case to see how much smoke it generates
( which would be better - white smoke or black smoke???)
I may have missed an obvious step, But I have been over it multiple times. I have not had a problem like this before building other systems.
Thanks for the help.
