Windows 10: Windows 11 unstable

I recently upgraded my PC to Windows 11 and I have had nothing but issues since installing it. My computer spends more time needing to be rebooted than actually using it.MS OneDrive will no longer log in, stating that there is a profile folder already setup and then if I select the same folder or try and change to a different folder it confirms there is an error with no troubleshooting information.If I try to run a graphics heavy game the PC goes blank and the only way to get it back again is to carry out a hard power down and then I need to switch the socket that the HDMI/displayport cable is

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
