Windows 10: Taskhostw.exe uses 24GB of RAM and freezes/crashed my PC

First off:

• Windows 10 Professional build 17134
• Intel i5-6500 3.2GHz
• 8GB DDR4 RAM
• MSI GeForce GTX1070 8GB

So for the past two weeks I've been having problems with my Windows 10 Pro machine:

• Applications will start to give errors, usually memory related
• Chrome won't work anymore
• Task Manager won't open
• Suddenly both my screens turn black
• Computer is completely frozen, I can't do anything and no sounds or anything play (Ctrl+Alt+Del, Ctrl+Shift+Esc, Alt+Tab don't work)

All that's left for me to do is to hard reboot my PC.


So I've been digging around, trying to find out what was going on. The Event View told me something was wrong with my memory. So here's what I tried

• Ran a Windows Defender offline scan
• Used MalwareBytes to scan my PC
• Updated my GPU drivers
• Increased the Pagefile from max 16GB to max 24GB (I have 8GB DDR4)
• Ran "DISM.exe /Online /Cleanup-image /Restorehealth" and "sfc /scannow", found and fixed some errors, problems persist
• Ran MemTest86, no errors found

I then decided to keep the Resource Monitor open and when I came back to my PC a while later I noticed it had pretty much frozen, but I could still see the Resource Monitor. Everything seemed to be normal but "taskhostw.exe" was using up 24GB or memory!


So that explains why I kept getting memory errors and why my pagefile was filling up. Any fix for this?

Which of these motherboards for 24GB 1600Mhz RAM???

Are you also suggesting that I go with the Rampage Extreme?

 

Desktop using 23,9/24GB of RAM


So recently I installed an additional 16GB of RAM in my pc and everything was runnning fine. I upgraded to Windows 10 and installed all the programs I use etc.
Now my pc was always using around 30% of the ram, however it soon became 60% and now it is using 99% from startup.

Here are some steps I already performed with the results from those steps:

• I ran a virus scan, with nothing showing up
• I checked my startup programs, nothing wrong with it in my eyes
• I ran sfc /scannow which showed up with nothing aswell
• I ran Kasperky AntiRootKit, nothing showed up
• I ran Malwarebytes which showed up clean
• I ran SuperAntiSpyware professional, nothing showed up(except some cookies which are deleted now
• I ran WPR -cancel in CMD, No trace profiles running

The programs that start when my PC boots are:



I hope anyone of you can help me find a solution to this. I know windows10 leverages memory better than windows 7, but it shouldnt be 100% use even when idle.

Here is a screenshot of my resource monitor:

 

Windows 10 shows Installed RAM 24GB (16GB usable)

I've upgraded from Windows 7 professional to Windows 10 professional. I purchased the PC with Windows 7 Home Premium but later updated to Windows 7 Professional. When I was using Windows 7 Pro the system recognized and used the 24GB RAM I've installed. Since
upgrading to Windows 10 Pro it shows that only 16GB RAM is usuable of the 24GB installed. I've tried using the msconfig option and it shows maximum memory to be 24GB.

I need help.
