I get low performance with ryzen 5 1600 and 1050ti

[Xaphire]

Hi guys,
I've recently built a rig with ryzen 1600, b350m motherboard, gtx1050ti
But the thing is i can barely get 40-50 fps in gta 5 and also the more i play the more my fps drops. This doesnt only happen in gta. This happens in all AAA titles. I have a few questions
The first one is; my case came with a frisby 500w psu, but I got my case for (was on sale) 50 dollars. Is the psu crappy and cant keep up with the pc?
Another question: this was my first amd build. So i didnt know how to install the heat sink while I was installimg it after the thermal paste was apllied I pulled the heat sink so the bond between the cpu and the heat sink was gone. Then instead of reappling it I just installed it like that. Can that be the reason?
The last question: My hdd is over 7 years old now and it is almost full can that be the reason?
Well the thing is İ need your help.

pls

Download MSI afterburner or HWmonitor and check your CPU/GPU usage and temperature. Give us full system spec, it may help.

The 1050ti is good for 60-80FPS with high settings @1080p if you have gone overboard with quality settings or resolution then 40-50 would be ok.
If you have tried low resolution and low settings and you still only get 40-50fps then it could be due to the memory issues that the ryzen platform still has.

Aside from the speed, you would want to get a good quality power supply, using a bad PSU puts your whole system at risk of damage.

Did you install Windows clean on your drive or just put it in as it was? Did you check temps on the system? With the way you removed the heatsink you want to make sure the CPU is not overheating.
