Large FPS Drops with new Pc

Hi, I build a nice gaming pc about a month and a half ago. I was grounded for a month and just got my pc back today. When I started playing games the FPS was shit. Alot worse then before I got grounded. I would get 80 to 90 fps in gta 5. Now i get like 20 fps. What do you think I should do or try?

Clean install the graphics drivers!

Download MSI Afterburner and Rivatuner (they come together).

 

Go to MSI AB's settings, OSD, and check the boxes for:

CPU cores (the individuals and the package)

CPU temp

RAM usage

Pagefile usage

GPU temp, VRAM, clocks, and usage

 

Post a recording with Shadowplay that is 5-minutes long.

I was just think that I pluged my Pc in a old surge protector .Could that be it?

[Daberlicious]

It could be and definitely try just plugging it into the wall temporarily. Considering the beast hardware its clearly not a bottleneck of any one component, either you somehow are thermal throttling in a mid tower case or theres a driver/some software issue

install chipset drivers on Windows. Yesterday a client phoned me for an APU giving trash performance (more than it should i mean ) and it was pinned down to CPU cooler plugged in Sys_fan connector and Chipset drivers not installed on windows 10. 

 

Try that, and also... plug your pc to the wall for testing purposes. Surge protection are mostly crap.
