Frames keep randomly dropping to 0

[MagikGoat]

I've had my pc for about two months now built it myself but I've been having problems while playing most of my games, its been dropping to 0 frames for a few seconds while playing games such as Rainbow Six: Siege, Rising Storm 2, and The Witcher 3.

My OS is Windows 10 and PC specs are:
GTX 1070
8gb DDR4
i5-7600K 3.8GHz
SSD 240gb

Uninstall video drivers in control panel and use DDU to remove all configs. Then download fresh new drivers.

Use ccleaner to clean your registry and blackviper to shutdown services you dont need. Use safe desktop a few at a time in case you see issues. If you start on tweaked desktop changes do 1 at a time so its easy to remember if you have issues.
