We have a three day old Idacentre A740 AIO PC. (windows 8.1 pro)

The system is up-to-date.

After we start the PC and "do notthing" the system interrupts taken 40% CPU time approximately.

Tried to find what causing we used xperf and wpm. I need help to understand the output of xpref.

I think the problem with the HAL.dll (or the ACPI.sys?) Any suggestion, how to solve this?

  • Try to look for missing drivers or update your drivers. But high CPU usage can be caused by many things. Perhaps installing updates in the background, trigged then the machine is idle. – DeDenker May 18 '15 at 12:00
  • -The CPU intterrupts constantly high... - Drivers up to date - hal.dll, ntoskern.exe, acpi.sys...this three which i can see... – holian May 18 '15 at 12:29
  • This definitely smells like a driver problem. Did you reinstall the system with a clean image? If so you might need to install the motherboard specific drivers. Acpi.sys and Hal.DLL are both generic roots of the device management hierarchy and I suspect the device specific driver would put that device into a more efficient transfer mode. – caskey May 19 '15 at 03:20
  • Yes. We install a new Windows 8.1 Pro - and after than we use the factroy driver disk. Than we use the recovery partition to install all factory application. Than made a windows update, intel update, nvidia update... – holian May 19 '15 at 07:30
