micro stutter while gaming

[jimmy1717]

Hello guys ,  i have tried everything and i still stutter in Fortnite and sometimes in CS GO , my  lowest fps in fortnite would drop each 1-2 min from 165 to 90 (i cap my fps to 165  because i play on 144 hz monitor)

pc specs : cpu : i7 8700  (6 cores 12 threads)

                 gpu :gtx1080 8 GB vram

                 ram: 2x8GB  2666 mhz (xmp enabled) (16-18-18-39)

  motherboard: ASRock H310M-G/M.2 

           Storage: 500 GB HDD , 500 GB SSD (everything is installed in SSD , HDD is empty) 

              PSU  : 650 W

           Monitor : BenqXL2411 , 144 hz 

all Drivers up to dated , tried 4 different nvidia drivers.enabled xmp in bios , disabled Hypperthreading technology.  tried those cmd commands useplatformclock No useplatformtick Yes disabledynamictick Yes. i'm on windows 10 pro version 1909  - 64 bit.

adjust Nvidia control panel for best  performance . power plan is on high performance. tried set priority on cpu usage for fortnite on high  then changed it back to normal. all my pc temps are decent . and i still get those micro stutters each 1-2 min  if  anyone could help me it would be much appreciated thanks.

It may be various bloatware running in background, uninstall everything you don't need or reinstall OS from scratch.

Or it may be PSU issue, what model it is exactly ?

all i know about the PSU it's a Cooler Master 650 W , i think Bronze certified but i doubt it's the PSU. and for the windows 10 1909 i disabled most of shits i dont need in settings. also my friend has windows 10  1909 and he didn't even optimize it and he doesn't get those stutter...
