I have a HIS Excalibur 9600 Pro for several months. I'd like to ask about something. I'm having several VPU recoveries a month. The issue is not heat or a game because I've checked the heat it was fine not even hot and it always occured while on Windows not in a game. I think it started to happen more frequently after I started to use Cat 4.5 but I'm not quite sure. What do you think the problem is?
