Question My gpu is limited after i had a power outtage and pc was turned off suddenly plz help

[skrrrt1]

So i was mid gaming when power ran out and my pc was turned off after reboot instead of getting 180 to 240 fps in apex legends i get 70 and gpu usage is at 40 % in resident evil remake in main menu gpu draws 360w and in game doesnt go over 220w and 40 % usage both games worked flawlessly before the power outage and my pc being turned off suddenly.
specs :
processor: i5 9600k OC to 4.9 ghz
moba : z370 p d3
ram : hyper x predator 2999 mhz ddr4 2x8gb dual channel xmp profile enabled
gpu : msi rtx 3080 z trio
hard drive : samsung evo 512 gb
psu : corsair rm750x
I had great temps around 78 to 82 with stock fan curve even at 90 % of gpu and cpu usage in res 4 remake and it ran from 90 to 120 fps very smooth on max w ray tracing and apex usually ran at 70 to 75 % usage on both gpu and cpu and around 70c.
Im pissed off cause i thought maybe it doesn't get power but it obv does as it draws 360w easy in main menu of res remake.
I reinstalled drivers ,removed and put back gpu , reverted to old drivers,unninstaled and reinstaled gpu in device manager.
I would appreciate if somebody could help me or had a same issue and solved it.

Thanks in advance.

Corrupted files perhaps.

Run the built-in Windows troubleshooters. The troubleshooters may find and fix something.

Try "sfc /scannow" and "dism".

Thanks for your reply.
I did what you suggested and there was some stuff that was fixed witch "sfc scannow" but it didn't solve the problem i get 100% cpu usage and 50 % gpu usage in apex when before it was 70-75 % for both and DISM everything was good.


i have this message in properties of my gpu in device manager i have no clue what is this
" Device PCI\VEN_10DE&DEV_2216&SUBSYS_389B1462&REV_A1\4&fa0c5&0&0008 requires further installation."

Use Task Manager, Resource Monitor, and Process Explorer (Microsoft, free) to take a closer look at system resource usage.

https://learn.microsoft.com/en-us/sysinternals/downloads/process-explorer

Use all three tools but only one tool at a time.

Objective being to determine what system resources are being used, to what extent (%), and what is using any given resource such as the CPU and GPU.

Start up with minimum apps being launched. Observe the percentages etc. as you launch other apps/games one at a time. Allow time between launches.

You may be able to discover which app, process, etc. is causing (for example) the CPU to go to 100%.

Takes some time and effort. Be methodical and watch carefully. Note the small arrow characters in the column headers. The arrows can be clicked to sort the data and put the high %'s at the top of the tables.
