ACPI.sys Causing system instability
Hi Experts,
I recently had my system Process running very high. It was taking between 60 - 80% of my processing power.
I installed process explorer and so i was able to dbl click the system process to see which threads were causing the problem. I found that it was ACPI.sys that was causing me grief. Through Process explorer you are able to suspend the thread which i did and found that i had no more problems. CPU instantly dropped to around 2%.
I have not installed anything recently nor have changed anything. There was a micosoft update from what i can see but thats it.
Last night i decided to restart my server as i had the need to and completely forgot about this Process and so naturally it tried to restart but it seemed to have frozen. CPU must have reached 100% and stayed there.
I came in this morning and had to restart again. It took a long time to reboot and cutting a long story short i stopped the ACPI.sys thread and it was running better. Today however everything is not running perfectly as i am seeing the CPU jumping all over the place and at times reaching 100%. Even after aplying my quick fix.
Now after a little research i found the location to be c:\windows\system32\driver
Does anyone know what i should do. Is there a patch for this. Is anyone else having this problem. I seemed to have identified the source but not sure what i need to do with it. I am not even completely sure if it was the microsoft update. how can i check and see the latest update. Is this through add/remove programs and then do a search on the KB....
Also just to eliminate spyware as a possible course. I ran 5 scans using different well recognised programs and they all reported no spyware
Please can someone help.
Ps:
I have a SBS server 2003 std edition.

Hi,
The above power options were default.
I spent many hours researching this problem and did not find a definite fix. I had however come across a forum where someone had reseated thier RAM and all signs of the problem was gone. I did the same and my problem went away. Now im not saying that if anyone is having this problem it will fix it but i would check all hardware is correctly seated in the machine: ie hard drives, memory, any cards etc
So Far so good and will be monitoring it.
Thx for the suggestions above and will split the points

It powers off absolutely fine. The problem must occu when the system is loading again and the ACPI.sys thread loads again from its suspended status. Thus taking all the CPU ussage.
I have a dual core 3.4, 2GB Ram
Fiitsue server
SBS 2003 SP2
150GB Disk
Not sure what HW you wanted. I do feel the hardware is fine however.
