I installed a PCChips M848A Ver5 replacement motherboard. Everything seems to work fine except that when I try to Power down the Computer it goes through the shutdown procedure, I believe actually turns off momentarily, and then immediately reboots. The same thing happens upon hibernation. The only way I can turn it off is with the switch on the power supply. I contacted PCChips on 12/6/06. They made the following suggestions:
Please clear your CMOs settings by using your clear CMOS jumper. Upon restarting the system, go to your CMOS settings and load optimal defaults. Save and Exit. This should disable any resume or wake on functions.
If this does not resolve your issue, try booting to safe mode and shutting down from there. If it shuts down with no issues you have a software issue. Try reinstalling Windows.
If this does not resolve your issue I suggest testing the motherboard outside of its case. This is to eliminate any issues that may be caused by the case itself. Setting the motherboard on top of the box it came with is a good way to do this. You can start the system by touching power pins (6 & 8) with a screwdriver or the tip of a pen.
I followed these instructions with no improvement. Since the system will power down properly in Safe Mode I have been searching for a software problem with no luck. Finally, I removed all the drives except one USB DVD drive, installed a completely blank, reformatted hard drive and installed a new copy of XP from the original Microsoft disk. I disconnected the Internet connection to be sure there was nothing else influencing the setup. Even this completely clean installation gave exactly the same result. The system would power down and immediately reboot. I ran "diagnostic startup" from msconfig and got the same result. I went to "device manager" and disabled the driver XP installed for the graphic display with no improvement. Regardless of the fact it will power down correctly in safe mode I believe the problem must be with the motherboard or the BIOS. I do not know any way to make a more basic installation.
As a final effort, I tried flashing the BIOS, however when I made the attempt I received the message Error 5 BIOS file not of proper size. I downloaded the file twice from two different locations on the PCChips web site with the same result. The problem did not exist with the Sanyo board that I replaced. I would appreciate any suggestions. I am out of ideas.
Incidentally, I tried contacting PCChips support email again. The return message was, PC Chips Technical Support will no longer answer direct emails that were emailed to [email protected]. They have instead put a support form on their website. I tried using this over a period of three days on two different computers. Every time I clicked Submit received the an error message, Error6 and nothing else.
