13R3 Painfully Slow

I've had my 13R3 QHD for about a year now. I've been keeping it up to date with latest and over the past few months I have noticed that response time is very slow for about the first 10 mins and the occasional slow responses over a period of usage. Just hitting the windows key and typing a program to launch is very slow. Clicking on a program or folder to open takes a long time.
What could be the issue? I've only installed Destiny 2/Battlenet, Adobe CC After Effects, Premiere, Lightroom and Photoshop, VLC, and Discord. Everything else on an external or Cloud.
I've left my computer in "stock" configuration and also tried undervolting with ThrottleStop. Anyone have an idea to what the problem could be or a fix? Thanks!

 

Use CrystalDiskInfo to retrieve SMART data of your SSD/HDD and see if it shows Good Or Bad.

 

Somewhat common Win 10 OS problem. If you open task manager during a slow period either or both RAM or Drive will be at 100% usage.

To Fix:

Disable in services: Superfetch, Windows Search, and while there, location services, and Dell Help and Dell Registration junk.

Also disable Skype on startup

Also possible fixes:

1. Identify if you are running the inbox AHCI driver (StorAHCI.sys):
   1. Open a command prompt with administrator privileges. Then type the following command in the command prompt window and hit Enter: devmgmt.msc
   2. Under IDE ATA/ATAPI Controllers right-click on the AHCI controller node and select Properties. This node is usually called “Standard SATA AHCI Controller.”
   3. Navigate to the driver tab and click Driver Details.
   4. If you see “StorAHCI.sys” in the list, you are running the inbox driver.
   
   
2. Disable MSI for the controller in the registry:
   1. In the same properties window opened in step 1.2, navigate to the Details tab and select Device instance path from the Property drop-down menu. Note this path.
   2. Open the registry editor by typing regedit in the previously opened command prompt.
   3. Navigate to: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\PCI\ <AHCI Controller>\Device Parameters\Interrupt Management\MessageSignaledInterruptProperties, where <AHCI Controller> refers to the device instance path you noted in step 2.1.
   4. Change the value of the MSISupported key from “1” to “0”.
   5. If you don’t know which controller your boot device is attached to, repeat steps 2.1 through 2.4 for all AHCI controllers found under 1.2.

 

Lol Skype.
Thanks I disabled the services you mentioned above and this did the trick! I don't have IDE ATA/ATAPI listed in my Device Manager, but all is good. Thanks for the help!
