CPU/GPU spikes while gaming

Hello,

I'm having issues playing games now due to this CPU/GPU max usage spiking while playing and it causes a lag spike.. it happens like every few seconds and it's driving me up the wall.. really not for sure where else to go with this issue.. it happens in nearly every game i play as well.

GPU: GTX 970 4gb
CPU: i7 4770k 3.50GHz
Storage: Samsung EVO 850 250gb for OS and 500gb for games
RAM:16gb
PSU:1000w

solutions I've tried..
unparking cpu, updating to latest gpu drivers, latest realtek sound and network drivers for my motherboard, latest chipset, cleaning out my pc, checking my temps.. it never goes above 70c while gaming.. both my gpu and cpu. even a clean install of Windows 10 Pro x64 bit, I've even done a clean boot and the issue is still occuring.. really at a stand still. I'm going to upload the screenshots of the in-game graph that is showing the spikes.

anyone? it's happening in BF4 pretty badly as well.

Well I don't exactly know what's going on but I had some performance issues too. I purposely turned off a service called "AMD External Events Utility" for my AMD R9 M375 and I had bad performance on games. Turning this on solved the problem for me. I guess enabling every service in system configuration should do it. Either that or you haven't got your GPU drivers fully working. My R9 M375 wouldn't show up on GPU-Z without removing the pre installed AMD drivers and freshly installing Crimson.
