Yes, all turned off. I tried the program you suggested, but I am not quite sure what to do with the results…
CONCLUSION
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines executed by a driver running in your system appear to be executing for too long. Also your system appears to be having trouble which may be attributed to SMIs, IPIs, CPU bugs or unexplainable stalls. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:12:50 (h:mm:ss) on all processors in the system.
