Hello buddy im just posting here as i have tried everywhere else and had no fix for this issue.
Ok i stopped playing with my Oculus Rift S for like a year now as i had this problem way back then and the issue stopped soon as i removed and uninstalled every thing to do with my VR headset i now know it has to have some thing to do with my VR head set.
What happens is after playing on VR and then play a normal game soon as i close that game and then go and open my browser my whole PC freezes i can not do nothing but hard reset after the reset PC runs fine.
It will be a shame to never play with my VR again as my boy loves using it but i dont want this to happen.
Many thanks if you can help if not i guess its time to shelve the headset again.
Just a little update for you, Every thing is working as it should, i am not sure if this is down to your new version of OTT or it was me disabling the auto power off on the usb controllers, touch wood i havent spoken to soon lol.
Thanks for the help mate.
