Hello, I recently built a new computer and its been having some issues. I reloaded windows clean and got all the latest updates and have all the latest drivers but on EVERY game I play I only run 45-50fps. I even go down to the lowest settings and get the exact same frame rate. My rig is...

Z170a gaming m9 ack
Msi gtx 1080 gaming x
Kabylake 7700k 4.2ghz
3 samsung 850 evos ssds
evga psu 750 watt gold edition
16gb ballistix sport ram ddr4
2 Asus MG248 144hz monitor 1080p

Help please... and I'm not overclocking or using v-sync and I have called Nvidia and they could not figure out the problem.
