Windows 10: Regular application crashes and BSODs

I am currently experiencing regular crashes of different applications on my machine. Most prominent are crashes of jvm applications which are always caused by anEXCEPTION_ACCESS_VIOLATION 0xc0000005When proceeding to restart those applications then my OS will eventially crash with either a PFN_LIST_CORRUPT or a MEMORY_MANAGEMENT exception.I have scanned for viruses with BitDefender and later switched to Avira because i wanted to rule out that my anti virus solution caused the problems.I have also scanned for viruses using a bootable KasperSky instance.I have tried running several diagnostic

Regular BSODs on my gaming PC

Note: before doing this, I've booted from GParted and did "Check and repair" on all my partitions, because about an hour ago someone suggested that to me in Discord.

Somehow, the "Health" tab is empty.

 

Random BSOD while browsing internet


BitDefender is nothing special. mwac.sys causes BSODs anywhere.
A tiny documentation can be found here: Solved Random BSODs - Windows 10 Forums
In that very thread, the suggested action apparently worked.

The storage and network filters of any third party antivirus can cause BSODs. Neither MBAM nor BitDefender is any special. For a regular antivirus, it may be shifted to an alternative; but MBAM has no alternative. So a clean install of the said program is the most feasible first step.
As far as the first step is not failing, it is better to not think for the second step. Because the BSODs are not universal, failure at the first step is not universal; and success at the second step is also not universal.
That is why I posted that my suggestion may work, or may not. Let us see where it goes.

 

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?
