Hi all, sorry to bother with this, I've seen and tried all old posts but looks like they don't work for me, or it's just me... Now the thing is, my PC is a bit old, probably soon, I'll buy a new one, but still I'd like to get rid of this problem...
I'm attaching LatencyMon pics so that You can see Yourselves.
Plus I paste the report:
________________________________________________________________________________________________________
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 that belong to
a driver running in your system appear to be executing for too long.
Also one or more ISR 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 0:10:31 (h:mm:ss) on
all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs):
201207,616101

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
