Frame drops despite good hardware?

I have complete problem and although I have in games such. Fortnite on middle settings often frame drops but I do not know why

Cpu: Intel Core i5 8400

Graphics card: EVGA Geforce GTX 1660 xc

Motherboard: MSi H370 Gaming Plus

Power adapter: 700watt Thermaltake tr2 s

RAM: 16gb ddr4 2666mhz

The first thing you should do to eliminate other problems if necessary, update all drivers.

This can be achieved with the iObit software: Driver Booster

It's free, but can also be purchased as you like.

If problems still occur, get in touch and then you will get more solutions.

1 problem is stop I'm afraid to update my bios because I have my motherboard before the same as I have now since I updated the bios went my LAN connection no longer because I then had to replace the motherboard

Or just update the lan driver before I'm afraid that it will not work again the wlan I'm not on my pc.

That's up to your drivers, you have to update them all then. The BIOS itself is not because if you have updated all the drivers, then your Wi-Fi works in the end.

Hmm since I'm doing everything I've always updated when I'm in the desktop is such a problem that the sound stutters

And the mouse pointer stutters then too

Unfortunately, it did not work. Can it possibly be because the graphics card is new that I have to wait for patchs?

No, that's not it. If I were there, then it would already have been fixed. It's hard to explain everything to you here, because it can actually be everything until you have checked sources of error and excluded.
