Here is a photo of the Heatsink-Fan component.

There are only 4 adjustments, and they are all on the corners of the black part (fan mould). They only allow me to remove and restore the component from the Motherboard.

There are no other adjustable parts.

So how could I separate the Heatsink from the Fan in future?

Also, there was a mouse relapse after I last posted.

So, I removed COMODO and Sandboxie and used pc for a few days successfully with no relapses.

Then I installed Sandboxie Plus (latest x64 version) and used a few days without relapse.

Then I installed COMODO and after a day and a half, there has been no relapse.

One of the main reasons I didn't want to upgrade Sandboxie was that it worked fine for 2 years without update.

And I find that the support forums for open-source can be less reliable sometimes.

I've emailed the Moderator for not letting a support thread I posted 3.5 days ago be showed publicly on https://forum.xanaso...wforum.php?f=14

Also, the forum keeps logging me out when I post.

I posted a support thread because the new system tray GUI requires a right-click to show sub-menu as it (to clear contents, launch browser), and doesn't allow me to see the sub-menu by hovering on it like I can with the legacy GUI.

I reread your first post about there being a wireless mouse.  Could some other device be transmitting nearby and interfering with the mouse?  Cell phone, Cordless telephone, neighbor's PC/router, fan etc?  You said the case fan was unreliable.  Perhaps when it runs it generates interference?

 

I can't really tell if there is a way to remove the fan from the heat sink.   Sort of looks like there may be tabs you could pry apart with a flat bladed screwdriver but I can't see for sure.   Do you have a part number for it?

 

The link after "...showed publicly on" just takes me to a login screen.  Probably need to take a sceenshot

The wireless mouse is a secondary mouse which has been off during for months except when I tried it a couple of times during mouse relapse troubleshooting before starting this thread.

My main mouse is wired.

The issue has been occurring with both mice.

At the time of posting, there were no changes to Cordless and Cell phone activity in the house.

I live in a Victorian terraced house. And although the walls aren't soundproofed, I don't think my neighbour has installed an overpowering router/fan.

Not sure about the intermittent unreliable fan.

I have edited to correct the link in my previous post, so you can view it now.

Sometimes if a driver is acting up we will see it in
Latency Monitor:

Go to

http://www.resplendence.com/downloads

Scroll down to

System Monitoring Tools

and then find

LatencyMon 7.0 (or it may be a higher number if they update)

Click on Download free home edition

Save it then right click and Run As Admin.  It will install and then start the program.  
It will tell you to click on the Start button but there isn't one.  
Instead click on the green arrowhead (looks like a Play button).   Let it run for about 20 seconds.  Then hit the red box to stop it.

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


Click on the Drivers Tab.  Click on the column header for "Total execution (ms)" once or twice until the biggest numbers are at the top of the column then take a screen shot (save as type jpg) and attach it.  
Click on the Processes tab then click on the  "Hard Pagefaults" column header once or twice until the big numbers are at the top of the column.  Take a screen shot (save as type jpg) and attach it.

There were some red errors first time I did it, but forgot to stop, so it ran beyond 30 seconds. But I re-ran the scan to stop at 20 seconds, and there were no red errors.

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):   714.133561
Average measured interrupt to process latency (µs):   3.320943

 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:                 firefox.exe

If you need some info on how to do a screenshot:

 

https://www.library....o/snippingtool/

 

If the problem is really with Windows Explorer then we can try disabling all third party extensions to it and see if that helps:

 

Download ShellExView.

http://www.nirsoft.n...s/shexview.html

Use this download:
http://www.nirsoft.n...xview_setup.exe

Once you get it installed, run it (right click and Run As Admin) and look in the third or fourth column from the RIGHT. It should say MICROSOFT. Click once or twice on MICROSOFT so that items with NO are at the top.
Select all of the NO items and then click on the red led looking icon in the upper left. This should disable all of the non-microsoft additions to Explorer. Reboot and see if you still get the Explorer crashes.

Do you really have some connected via FireWire?  That's the only driver I see in the top 10 ISR counts that I don't expect to see.

 

Processes shows Windows Explorer as a culprit which is very unusual so ShellExView may do some good.

My sound card is M-Audio FireWire Solo. I prefer the frequency response compared to more modern sound cards.

I do notice that sometimes when I click and drag a window very fast, it stutters across the screen.

Btw, I already disabled all non-Microsoft entries in ShellExView earlier in the thread.

Sorry about that.  Didn't go back and read all of the old posts.

 

Start, All Programs, Accessories then right click on Command Prompt and Run as Administrator.  Then type (with an Enter after the line).

File Signature Verification window should appear.  Hit Start.

 

If it finds any that it doesn't like it will show you them when it is done.   If it finds any make a screen shot and post it.

 

You mentioned earlier that the case fan didn't seem healthy.  Does it make noises?  If you stop it with the eraser end of a pencil does it start up again right away or is it very slow to get back up to speed.  The fan may be controlled by a thermostat so it may not run all of the time.

 

Can I see a new VEW log?
