Hi guys,
I recently overclocked my i5-4690k, and I ran prime95 for a couple of hours, and there weren't any crashes and the temps were good.
However, almost everyday, when I boot up my PC in the morning, my Windows startup sound stutters, and my entire PC lags afterwards. The odd thing is, that my temps are good, and my CPU and RAM usages are really low too. I have no idea what causes this. The fix that I found is just a reboot. When I reboot I'm good to go for the rest of the day.
Does anyone have an idea what causes this? And how to fix it? Increase core voltage? Decrease core multiplier?
