Crashing all the time. (ACPI BIOS is attempting to read from illegal IO port address)



I have a really annoying problem. My computer restarts very often, and when i look in he event logger, i find this message every time:

AMLI: ACPI BIOS is attempting to read from an illegal IO port address (0xcfc), which lies in the 0xcf8 - 0xcff protected address range. This could lead to system instability. Please contact your system vendor for technical assistance.

Does annyone know what's wrong??

it just happened now when i wrote this post! arrrghhh...


no, my BIOS is the newest available.

it must be some kind of software. It hasn't been a problem earlier, and this installation of XP conttains a lot of programs and stuff....

You might consider rolling your bios back one or two revisions and see if that helps. That article was pretty specific that it is a ACPI bios issue.

EP, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS

Been running around Quora lately, luv it there!
