[SOLVED] can i get lag because of my graphics card?

[leffylolz]

I have this pc for over 3 years now and its not the best. My internet is okay and i never lag in games but recently when i try to play league of legends i lag in game and around 10 minutes in get very high ping causing me to get disconected but when i alt+tab my ping goes back to normal but if i go back in game the ping goes up again. I tried to repair the game but nothing changed and i have the graphics low so is it my pc's fault?

You should provide more information than what you've given. Please list your full system's specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

Also include the titles you're gaming on your desktop. To add, include the internet package you're working with and the sort of ping times you're seeing. Latest BIOS update for your motherboard? Latest drivers, manually installing?

no. or at least not your gpu.
possible problems:
wireless card driver/ethernet driver
windows firewall(unlikely)
QOS on router(dedicates bandwidth based on importance. try turning it off)
something on your computer may be sucking up bandwidth try closing other apps
or you are unlucky and got a bad server
