Compattelrunner.exe came back.  It should not start without the task.  Let's make sure it is the real file.  Bring up FRST but do not hit SCAN.  Put

compattelrunner.exe

in FRST's Search: box.  Hit SEARCH FILES  You will get one file.  Copy and paste into a reply.

Thank you.

Appears to be the same file as on my PC.  Let's try replacing the file with a dummy.

 

Download the attached fixlist.txt to the same location as FRST

 fixlist.txt   730bytes   190 downloads

Run FRST and press Fix
A fix log will be generated please post that

Reboot if the fix doesn't reboot it for you

Run FRST again as before.  Make sure Addition.txt is checked and hit Scan.  Post both logs.

 

Then run Latency Mon again and show me the Hard Pagefaults as before.

 

[daba]

Thanks. This didn't quite run to plan. I'm unsure whether these logs are the previous ones (I haven't deleted any of the stuff we've gone through from my desktop, perhaps I need to) or whether those are stored in FRST Older and in fact these are okay. Anyway, no they're not where I thought I was saving them. Can't locate them.

 

So, may I ask: should I first delete old FSRT stuff and if so which exactly and then at lunch after work I'll start again and try again. Sorry.

 

[RKinner]

No need to keep old logs from FRST.  Since you have posted them on the forum they will always be available.  If you are confused as to which log is the newest, check the date.

 

It looks like we have finally killed off compattelrunner.  It's not causing pagefaults any more.  What does the summary report from Latency Monitor look like?

 

(Edit, Copy Report text to Clipboard then move to a REPLY and Ctrl + v to paste the text into a reply. )

[daba]

Oh, okay. Thank you.

CONCLUSION

_________________________________________________________________________________________________________

Your system seems to be having 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  0:00:25  (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):   847.10

Average measured interrupt to process latency (µs):   10.408622

 

Highest measured interrupt to DPC latency (µs):       791.60

Average measured interrupt to DPC latency (µs):       3.098982

 

 

_________________________________________________________________________________________________________

 REPORTED ISRs

_________________________________________________________________________________________________________

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

Driver with highest ISR routine execution time:       ACPI.sys - ACPI Driver for NT, Microsoft Corporation

 

Highest reported total ISR routine time (%):          0.008411

Driver with highest ISR total time:                   ACPI.sys - ACPI Driver for NT, Microsoft Corporation

 

Total time spent in ISRs (%)                          0.009499

 

ISR count (execution time <250 µs):                   377

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.

Driver with highest DPC routine execution time:       ACPI.sys - ACPI Driver for NT, Microsoft Corporation

 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.

 

 

Process with highest pagefault count:                 none

 

Total number of hard pagefaults                       0

Hard pagefault count of hardest hit process:          0

Can you make a snip of the Drivers page in Latency Monitor?  Something like this:

 

[daba]

Sure, thank you very much.

[RKinner]

I think you should check your PC maker's support website for a new version of the BIOS.  That's usually why we see ACPI.sys with so much delay.

[daba]

Thank you very much for all the help, patience and advice. I put 'New BIOS for laptop' into Dell.com's search box and just got a list of new laptops.I guess I'm s****ed!

[RKinner]

Give me the part number and service tag for your laptop.  Should be on a sticker on the bottom.  I'll see if I can find something.

[daba]

Thanks a lot, much appreciated. If these aren't quite right, there's another one too: 

63J4YN2 2018

13274236766

[RKinner]

https://www.dell.com...NUQT090/drivers

 

There's a new BIOS version 1.9  (you have 1.4)

 

You should also get

 

Intel Rapid Storage Technology Driver and Management Console

[daba]

Thank you. Sorry to be thick but does 'getting' the new BIOS and Intel Rapid Storage Technology Driver and Management Console mean simply downloading them from that download list page? Download and run? Thank you.

[daba]

The Dell driver assist found four in total including the BIOS and the other one you mentioned. When I clicked download it asks me what file to download to, or make a new file. Also that the BIOS is a manual install - unlike the others - but I've no clue what that all means in practice. Could you please guide me a little? Thank you so much.
