I purchased an AN515-53-52FA from Best Buy, which comes with a 1TB HDD but no SSD. I then purchased a Western Digital Black 3D 500GB NVMe drive and installed in the AN515-53-52FA. I did a clean Windows 10 install onto the NVMe drive from the recovery USB disk I made from the original HDD before wiping it for a storage drive. I have all the latest drivers installed from Acer, Intel, and WD. The Western Digital SSD toolbox shows that I have PCE 3.0 x4 connections to the mother board. My bios is set it AHCI not Intel Optane for the NVMe drive.
Everything was working great until today. Now disk access to the NVMe drive is super slow. For instance the icons in the windows explorer window take forever to show up.
I've uninstalled bit defender and a couple other pieces of software, not that I'd installed anything in the last 24 hours. All I have now is a basic windows install, some steam games, blizzard games, etc. Also when I right click on anything the menu that pops up is blank. And while uninstalling programs I had to open and then minimize windows task manager to get anything more than a clear border to show up on the programs uninstall windows.
I have also added a second 8GB of ram, same speed specs as the original, but that was 2 weeks ago and I've run a windows memory check which came back clean.
Any thoughts as to what might be causing this system lag?
Additional thought.... will have to try when I get a chance. Nvidia graphics driver was updated yesterday.... would this affect windows desk top and disk access speed???
