So, to start with, when I turn on the PC it won’t go straight to loading windows, I always have to press the F1 button first. Then it happens sometimes when I play that I hear the system sound of “critical stop” and the game freezes and if I try to alt-tab I can see al the tabs but if I select one it won’t open. Also if I press ctrl-alt-del to open the task manager, I can see it in the alt-tab menu but if I select it it’s the same, I can’t open it. I have to log off the user and log on again to be able to do anything (obviously being disconnected from my game). And I constantly hear the USB device sound connecting and disconnecting - but nothing seems to actually connect or disconnect (I’ve tried to check in Manager or with usbdeview and nothing showing there - I just muted the sounds in the end). Do you have any idea what could be causing these?
