Windows 10: Unstable GPU and system crashes after latest update.

Hi,


I have an Nvidia GTX780 which started acting weird after last major update, started with getting some system crashes while in game then getting artefacts and crashes on the desktop too.


I was getting error code 43 which is when windows shuts down hardware even though I was still getting a picture... after trying a few things that's gone and the device is seen correctly.


Some games won't boot at all, some will boot and crash later and some just before gameplay, setting the power limit to 90% makes it stable in some games, also benchmarks work at expected performance/temps.


Also noticed under system information that I have installed 16gb of ram but only 8GB under "Total Physical Memory" same amount reported on Task Manager. The system didn't get any recent upgrades and ram was seen as it should before.


To note that everything works as expected under Linux though I can't test demanding games for lack of disk space.


So far I've tried:


Updating Drivers

Disabling/Enabling/Uninstalling card from Dev Manager

Flashing GPU rom

Repairing Windows from CMD errors found and repaired

Clean Registry

Checking HDDs


System doesn't seem to crash anymore but every other problem is still present, any input much appreciated!

:)

 

Help with unstable system

latest update,
I have changed psu for xfx 750W and keeping to stock values and use on board graphics, the system seems stable , has been for several days. If I try to unleash, then Its prone to occasional crashing.
So next step was to put HD6950 in with CPU in stock setting.
System very unstable again. crashes after about 5 mins.
I have lots of fans , CPU temp ~35deg, HDD ~30deg,
HD6950 ~ 49deg
When system crashes, I dont get bSOD but a grey screen with thin black vertical lines. I then have to re-boot . I get back, Windows reports error with usual 124 error.
Could the CPU be an issue ?
Dont have another to test.
Any suggestions ?
Thank you

 

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.

 

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?
