Windows 10 Fall Creators update slowed Dell Inspiron 3541 down to a crawl!

Since you have done a clean install of Win 10 and I assume not the Fall CU the problem would appear to be something other than the Fall CU and it was just coincidental.  

As it runs OK in Safe Mode, not all the device drivers and startup items are loaded in safe mode.  Could still be a device, along with some software service.

The free Resplendence Latency Mon may help in locating what is causing the problem.  Its a very useful tool.

The clean install was FCU version 1709.  I will try the resplendence latencymon, and see what I can see.

I thank you for the response.

I am trying to figure out what latencymon is telling me here.   But I wanted to thank you again for your help and let you see below what I am working with;  Thanks, Roy

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):   397.258970

Average measured interrupt to process latency (µs):   8.624754

Highest measured interrupt to DPC latency (µs):       247.360679

Average measured interrupt to DPC latency (µs):       3.350291

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.

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

Highest hard pagefault resolution time (µs):          0.0

Total time spent in hard pagefaults (%):              0.0

Number of processes hit:                              0

Sadly that did not help.

I would go back to the Windows version BEFORE the Fall CU and make sure it still works OK with that version.  Then let it do the upgrade.  

I had a problem with Edge browser after the update, as did several others according to posts on the www.tenforums.com  

I had a Macrium Reflect full disc image (backup) made before the upgrade.  I restored my system to that and then let it do the Fall CU again and Edge now works OK.

I'm experiencing the exact same problem (same hardware, same symptoms). Were you able to find a solution?

I am having the exact same problem with the same laptop.  Did a fresh install of Win 10 to no avail.  Disabling the Radeon adapter gets rid of the lag but now video is a lost cause.  Is there an alternate display adapter?

dodgerc, would you happen to have a link to the driver you used to solve the problem?

Please link us, I'm experiencing the same issues.

Just fixed this as well.  Here is a Dec 2016 driver... it works without the hiccups.

Thank you so much for posting that link!  That HUGE slow down plagued me for months!  Learned a lot, because I thought it was a hardware issue, so I bought new RAM and installed it.  Thought it was an HDD issue, so I bought a new one and installed it.  Then, I thought it was the Meltdown/Spectre patch causing the slow down, so I actually ended up setting up a dual-boot system with the latest version of Ubuntu.  This whole time it was the driver. Dang, I feel dumb.

Is there any other solution than downgrading the driver?

Same issue here and disabling the Radeon helped the problems but made videos unwatchable. I went to Dell.com, searched for drivers by computer model number, chose windows version and video in their respective drop down menus. There was only one driver for me to choose once I filtered. I installed the “new” Radeon driver and all issues were fixed. I’m not sure if it was a downgrade or not but for our purposes so far so good. I know this is an old question but I figured if someone else goes down this path it may help someone fix their issue in the future. 

Thanks for the info!
