Have you plugged your display into your gpu and not into your motherboard?

I'm not sure but I'd say the monitor simply doesn't support the use of custom resolutions and refresh rates.

When installing ubuntu, just select the 40Gb partition, and use '/' as the mount point. This will mean that your /home folder will be placed directly under '/' as opposed to a seperate location. This sounds like a good option.

You should only split up your boot drive in two partitions, your secondary drive will be accessible by both the linux and windows install if they have the right file format. I recommend using NTFS. This way you won't end up running out of space on one partition before the other. As for you boot drive partitions, a Ubuntu install is nowhere near the size of a Windows install, so I'd split that 120gb ssd in 80-40 rather. Then again, it depends on how much you'll use one over the other.

Looks to me like you need to sit down and take your time to manually backup every single file you'll still need to an external drive, or online backup location. It's a lot of tedious work but it'll save your life in the event of a hardware or software failure in the future. If you're thinking about switching to a different OS you should definitely make sure you've got all your files backed up before you try installing something new. Starting with a fresh install sounds exactly like what you need. What exactly do you mean by not being sure that you won't ruin any of your files?

Glad to hear that you're willing to give Linux a shot, but have you tried a clean windows install? Sounds like your current windows install is just having some issues that could possibly be fixed by doing a clean install. If that fixes your problems you'd be better off that way because you could still use Premiere. If you want to use Linux anyway, I would suggest that you stick to Ubuntu 18.04 because it's the most beginner friendly and compatible with KdenLive. Still looking for more? Try browsing around a bit on https://distrowatch.com/. It has loads of Linux distributions listed on there, so you can find the one most suited for your needs. I suggest sticking to debian based distros to keep things simple.

Use a PCIE riser to raise the lower card up to the same height as the high card.

Maybe the game's using the iGPU. Try setting the minecraft.exe application to "more beautiful" in the nvidia control panel

Everything seems to fit pretty snug in that case, but I'd still put some foam in between the components, or even disconnect the gpu and wrap it in something.

In my area those go for €190-200

Kali can quickly use 8gb+ of ram on it's own if you're using vulnerability databases.

execute this command in powershell Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"} EDIT forgot to close bracket, sorry

I'm just taking a guess here but maybe you've got a broken keylogger installed on your system that looks specifically for wow to fire up. Can you install windows on another hdd and see if the issue persists?

What do you mean with "allow other users to manage a database"? Inserting/deleting/editing records? Adding columns?..
