Sorry, but I came into this thread initially with a response to just one problem (the missing dump files) - but I'll attempt to address your concerns here:
For the Logitech problem there's several approaches to try.
Start with this:
- right click on each one and select "Uninstall"
- then right click on the top entry (GrimsLenovo) and select "Scan for hardware changes"
If the system still shows errors on these devices then:
- download a fresh installation package for your Logitech device from the Logitech website
- uninstall your Logitech software using Control Panel...Programs...Uninstall a program
- install the freshly downloaded package and see if that fixes the errors.
As for the missing dump files, here's a brief and incomplete DRAFT description of how memory dumps are generated:
BSOD Crash Dump Generation
You have 2 pagefiles - one on the C: drive and one on the D: drive
Please set max and min on both for 8.5 gB in size (you may not get this much off the D: drive, but give it a try).
