Within the past month this issue has started. I'll start up my PC when it's off or wake it from sleep, then I'll use my PC for a couple minutes until the mouse cursor starts to move sluggishly. After about 5-10 seconds the screen will freeze and become unresponsive. Sometimes I can still move the mouse around unable to click anything and other times the mouse will freeze. After a couple of minutes everything will return to working normally. My PC has no problems running demanding games or just with normal use afterwards. This is only a problem right after a clean boot or a wake up from sleep. Once the freeze passes the PC works perfectly. I've had this PC for years and this is the first time encountering this issue. Any ideas what could be causing this?
