    Windows 7 CPU pegged at 100%

    As long as I don't let it sleep, there is no issue. HALMACPI is quiet, response is fine. So I really can't do any monitoring for strange activity in the "good" state and my PC is near-unusable in the "bad" state. I don't particularly like not having the "sleep" function available, but will live...

    Windows 7 CPU pegged at 100%

    With the many threads I found blaming HALACPI for blue screens and freezeups, while I can accept your statement that it is probably not directly responsible, I have to think that it may be "fragile" in that it does not deal successfully with every possible peripheral. When the system comes back...

    Thanks! I disabled sleep mode and left the system on overnight. HALMACPI.dll is only using 1.59%. CPU usage is low; idle process ranges 90-99%. The powerconfig trace showed all the USB warnings and disabling of sleep mode, plus the below regarding firefox. Suggests to me firefox is being a...

    Windows 7 CPU pegged at 100%

    It is the "Hardware Abstraction Layer" dll - part of the OS written by Microsoft. It is in the system32 directory. It's been around for years, blamed in various rashes of blue-screens and instances where mouse and keyboard are frozen after wakeup from idle. Modify date of 11/20/2010, but the...

    Windows 7 CPU pegged at 100%

    Well, I've moved on from bcssync being the culprit. Now I find that no matter what I disable, deinstall, or remove from startup, the behavior: Does not change when processes are killed Is not there after booting - cpu usage is 1-2% unless apps starting, and then settles in at <10%. This is...

    Yes, BCSSync is an Office 2010 component that synchronizes local files with versions stored online in Sharepoint 2010. Apparently there is a virus that implants itself in the BCSSync image and causes lots of thrashing and high CPU usage. Removing BCSSync.exe stopped the issue temporarily, but as...

    Thanks for your response. I drafted a reply yesterday, but it seems to have gone into the ether. Here it is in brief: The original post data was a copy/paste from "Resource Manager" - the column alignments didn't hold so it was hard to interpret. Here is a snapshot from this morning...
