Did as instructed.  Laptop considerably faster now.

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be suitable for handling real-time audio and other tasks without dropouts.
LatencyMon has been analyzing your system for  0:00:31  (h:mm:ss) on all processors.

SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name:                                        USER

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed:                                   20 MHz

Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.

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):   267.775314
Average measured interrupt to process latency (µs):   15.826703

Highest measured interrupt to DPC latency (µs):       188.927516
Average measured interrupt to DPC latency (µs):       2.895163


_________________________________________________________________________________________________________
 REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Highest ISR routine execution time (µs):              20.310
Driver with highest ISR routine execution time:       hal.dll - Hardware Abstraction Layer DLL, Microsoft Corporation

Highest reported total ISR routine time (%):          0.001440
Driver with highest ISR total time:                   hal.dll - Hardware Abstraction Layer DLL, Microsoft Corporation

Total time spent in ISRs (%)                          0.001913

ISR count (execution time <250 µs):                   284
ISR count (execution time 250-500 µs):                0
ISR count (execution time 500-999 µs):                0
ISR count (execution time 1000-1999 µs):              0
ISR count (execution time 2000-3999 µs):              0
ISR count (execution time >=4000 µs):                 0


_________________________________________________________________________________________________________
REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

Highest DPC routine execution time (µs):              321.020
Driver with highest DPC routine execution time:       ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation

Highest reported total DPC routine time (%):          0.024671
Driver with highest DPC total execution time:         storport.sys - Microsoft Storage Port Driver, Microsoft Corporation

Total time spent in DPCs (%)                          0.075699

DPC count (execution time <250 µs):                   11764
DPC count (execution time 250-500 µs):                0
DPC count (execution time 500-999 µs):                2
DPC count (execution time 1000-1999 µs):              0

DPC count (execution time >=4000 µs):                 0

 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.

Process with highest pagefault count:                 avpui.exe

Total number of hard pagefaults                       3822
Hard pagefault count of hardest hit process:          2202
Number of processes hit:                              8

Do I have to delete the programs that you asked me to install?

Could you show me the Processes page  from Latency Monitor with the PageFaults at the top?  You should be able to use the snipping tool (save the file as .jpg then you can attach it to the reply)  Probably there is nothing more we can do to stop them other than adding more memory (you only have 4 GB - 8GB is recommended for 64 bit systems- you can use up to 16.  Speccy says you have one stick of 4GB and 2 slots so adding a second would be easy.  Don't know if you have Amazon over there but they have the exact same (HYNIX HMT451S6BFR8APB)  4GB for $18  You need DDR3L not DDR3) but I want to be sure we are not missing anything.

 

Also make a new Process Explorer log but first click on the Working Set column header once or twice so the processes with the largest memory use are at the top.

 

We will uninstall everything as part of the cleanup when done but you can uninstall Speccy now.
