Windows 10: win32kbase.sys crash

Within the last week my computer has continuously blue screened. at least 4 times now. prior to this week I have had several circumstances in which my computer would crash but would not display a blue screen. rather my monitor output would cut out, I could still hear computer audio, but I would need to force hold the power button to cycle the machine.As of this week my first blue screen crash was VGK.sys and now today win32kbase.sys. I am unsure of whether its related but google chrome has also frequently been giving me Oh Snap "Status_access_violation"Any help would be greatly appreciated, I

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.

 

GPU-Z 0.8.7 crash on launch

W1zzard is asking you to test so that he can suggest next steps and be able to troubleshoot the issue you have.
If another version works, it would be one set of steps.
If several other versions also fail/crash, then it would be another.
