If *you* are not sure, what do you want us to do remotely? Expand our guessing game? Because we can't possibly know what's on your computer and what's not! Hey, I bet if you did a clean install of Win10 you wouldn't have that problem...

Again, we can't possibly know what's going on with your computer, unless you give us more details. Unless you start uninstalling software that may affect the performance, with patches and antivirus being the usual suspects.

Check what has changed in your computer between the working/not-working good states. Then you'll have narrowed down the suspects list.
Assaf wrote:you mentioned spectre/meltdown patches, is there anything that needs to be configured differently if those patches were installed?
Oh, no, you can't change anything about that. Just search with your favorite engine the terms "spectre meltdown"...
