So my laptop is fairly new and i started to notice how slow it was despite having decent specs on
I tried on my own to fix the problem by replacing HD with SSD and just doing general tweaks within the settings for best performance still i notice it isn't fast for what it should be

specs :
Toshiba satellite
i7 -5500u cpu with 2.40GHz 2.40GHz
Ram 8GB
graphic card nvidia geforce 930m
SSD 250 GB

Problem: really bad fps max i get on low settings is 50 sometimes 60 depending on the game

i tried to switch to high performance battery option it gets even worst drops more

Help me i gave up completely to fix it and i can not afford a new one as this one already cost me nearly £900 from argos, to think of it maybe i got scammed for that price i should be getting a lot more
