Windows 10: Windows crashes again and again

Hello, My computer keeps crashing again and again, showing me the blue screen of death with these 5 errors:Reference by pointer Kernel Security Check failure System service exeptionBad object headerirql not less or equalI did try the solutions mentioned in other threads such as going back to older drivers, launched from cmd « sfc /scannow » ,« mdsched.exe » and also « chkdsk.exe /f /r » but it didn’t solve my problem. Then, I tried to use « verifier/querysettings » but my computer didn’t crash since then, although I’ve read I should wait for it

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?

ive watch my temps and both the cpu and gpu are within normal ranges. when it freezes it simply freezes the image and stops the sound. i must reboot to get back to windows.
