Mobo: Epox EP-8KTA3PRO
Processor:AMD Athlon 1.4Ghz
Memory: 1 GB
OS: Windows XP
My PC randomly freezes without any error messages or entries to the event log. I can have an uptime of 5 days or only 2 hours. It typically occurs while playing games (but not always) and has happened while surfing the net with nothing else open.
I have reinstalled the OS twice, I have upgraded the hard drive, I have tested the memory. The system temps are all decent (low-mid 30s).
Two things lead me to believe that the motherboard is at fault
1. Is this error message from the event log when I boot up:
AMLI: ACPI BIOS is attempting to write to an illegal IO port address (0xcf8), which lies in the 0xcf8 - 0xcff protected address range. This could lead to system instability. Please contact your system vendor for technical assistance.
2. Is the fact that my ethernet cards keep becoming unrecognizable. After I reboot from the freezes sometimes my 1st linksys ethernet card disappears, if I reboot, most times it will come back. However, yesterday when I booted, the OS recognized it as an AMDTEK card, when I tried to change the drivers Windows told me it could not start the card. I pulled the card (slot 2) and inserted another and got the same message, so I left that PCI slot empty and moved to the next one available (slot 4)and it worked just fine. Today the ethernet card in slot 3 is not working properly.
I know this is rather long but I am trying to be thorough in order to identify the problem.
