I just replaced the motherboard in my desktop. I've got the new one installed, and everything seems to be right. However, a couple of processes cause the system to shut down immediately. When it shuts down, the power button becomes inoperative. I have to pull the plug until the power light on the motherboard goes out. After that, I can put the plug back in, then press the power button to boot.
The following two things cause this hard shutdown:
1. Pressing Ctrl-Alt-Del after the system BIOS POST (e.g. once Windows Setup has started loading, or in my IDE RAID card BIOS)
2. After Windows Setup (running off CD) starts, it goes to the 'Setup is inspecting your hardware configuration.' The blue setup screen, and it begins loading the various drivers at the bottom. At the very end of the driver loads, it says 'Enter Windows Setup' at the bottom of the screen, then the system shuts down. This is right before the point I would expect to see 'Welcome to Windows Setup. To Setup Windows XP, press Enter.'
Could I have something wired wrong onto the motherboard.
The power supply is a 350W with the single ATX connector onto the motherboard. There's two drives, CD burner, GeForce AGP video and Soundblaster audio, which were all in the same system with the previos motherboard.
Could it be some power mode in the BIOS settings?
Any help would be appreciated.
