I've got a really weird problem , 2 days ago I've built my new rig and it booted up perfectly , I had some AMD driver problems and solved on my own but one remained , everytime I tried to overclock my CPU , even by 100mhz my system's performance dropped a lot , Aero disabled automatically and had huge framerate drops in games (from 100/110 in BF 4 to 15/20) and then went up again , this happened every 5 seconds or so . This happened in Windows 7 , now I installed Windows 10 to see if anything changes and when I try to overclock (in the OS not in BIOS) my system just freezes for about 15 seconds and then reboots , so since overclocking in Windows wasn't going to happen I tried overclocking in BIOS but even so the story would repeat again and the PC wouldn't boot at all so I had to reset everything to default . This is very weird because even with the slightest increase in clock speeds the system just refuses to work . Does anyone have an idea of what should I do or what the cause of the problem is ?
