Windows 10: Games crash/hang on startup

Recently most of the games on my computer Windows 10 v21H2 have been crashing or hanging after launch. Some games work fine and some load for a few seconds before they are labeled as Not Responding in task manager. I have already tried updating graphics driver. Running a display driver uninstall tool and installing from scratch. I have also tried down clocking my GPU GTX 1070, but that didn't work either. I also tried disabling real-time protection of Windows Defender. Nothing was installed before the issues started and games have only been installed through Steam, Battle.net, Epic Games,

HD 2600XT Hangs and Crashes

I can probably play cod4 or any other game really for about 45-60 minutes before my system hangs and my card crashes and my screen goes blank, i know its only my card because my system doesnt restart, my card fan stops running on full from its riva override, and soon thereafter my screen comes back on in 800x600 and i cant access the card's drivers to change the res or anything, so when it hangs and crashes i just resort to manually restarting.

one thing i think i could try is to bite the bit and install the latest drivers, i've been holding off on that.

but if there's anything else anyone can think of, or if someone has had the same problem as me. go for it and give me some suggestions.

in before buy the 4870. (already on my wish list)

 

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?

 

Can't get GPU-Z to start with Windows 8.1 startup

I'm not sure how to do that. Could you list the steps for a noob?
