had problems getting the pictures to show with the spoiler function, so i'll just use the copypaste function from the program: _________________________________________________________________________________________________________
CONCLUSION
_________________________________________________________________________________________________________
Your system seems to have difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. 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 0:06:02 (h:mm:ss) on all processors in the system.
