Low fps and graphics even though recommended is high/ultra

[forbidenkingdom123]

Until May or June 2017. my graphic card was working great, i played games and they run smoothly, but then suddenly (i think it was after windows update (win 10)), its like my gpu is connected, but its not, not working properly like i don't have gpu at all. I am using Nvidia GeForce GTX 570. I know its far from the best, but on games like league of legends and etc i was more than satisfied. Now on the menu and loading screen of the game everything is fine, i also went down to settings and it was recommended all on ultra/high, but in game/match graphics are low of the lowest and fps is around 20 (if im lucky). I tried to change OS (from win 10 to win 7)/changed to older driver/Checked if its not beacuse of my CPU and it's overheating, ahh i don't know... im left with 2 solutions. Either is GPU old and need to be replaced, or my slot on motherboard is malfunctioning.I don't know who to ask anymore or what to do, i hope u will finaly help me at least pinpoint what is going on.

This is my setup:
CPU -Intel i7- 3820 3.60GHz
RAM - 8gb (DDR3 i think)
Motherboard - ASRock X79 - Extreme4
GPU - Nvidia GeForce GTX 570

Try DDU and install fresh drivers as well as chipset driver and all motherboard drivers.

If the above solution does not work, Make sure your Power plan in windows is set to high performance, and go to Nvidia Control panel, Select the Manage 3d settings, scroll down and change the "Power management mode" to Prefer Maximum performance.

Some games that don't tax the GPU enough the GPU will remain at a lower clock, which could cause and has been known the cause issues. Normally seems to happen to people playing CounterStrike but it can happen to other games.
