Games suddenly very slow after power outage!!

[Ruddi]

So I was playing PUBG the other day, when the power suddenly went out. I eventually got it back on, started my PC back up, booted up PUBG and had 1 FPS ingame. I tried restarting my PC, checking game files, checking after other forum posts, but I couldn't find anything.
The game is installed on an SSD.
I tried reinstalling the game, nothing happend.
This is also happening on other games installed on the SSD.
Should I format, or wouldn't that make a difference?
Thank you in advance..

Just check that CPU & GPU are working properly and at their full clocks.

How do I check that?

Are you sure the Monitor is connected to your dedicated GPU in the slot?
Not connected to the Motherboard.

I would invest in a ups for the future but it sounds like something inside your computer might had gotten damaged because of a power surge or such since you do not use one.

My first suspect was that some files got corrupted on the SSD, if it was that, would it affect all my games and would it help to format it?

Nothing would really run properly if that was the situation for real.

Run stress tests on your CPU & GPU outside of Gaming to check they are working properly.
