@Iraburdine Hi and welcome to the community. 🙂 Adding some things you might want to try. > [@Brave uses a lot of resources causing fatal errors](https://community.brave.app/t/brave-uses-a-lot-of-resources-causing-fatal-errors/391483/2): > > Hi @HectorCastillo Try this: Disable hardware acceleration Clear browser data If using nvidia go to settings and choose AUTO-SELECT. Restart browser. If CPU still too high, Hold CTRL+SHIFT+N then test in Private Mode. if CPU is OK, an extension might be causing the problem. > [@Update broke DNS?](https://community.brave.app/t/update-broke-dns/283787/4): > > Click on run/search, type “cmd”, right click "Run as admin" Then run the following in the black window: netsh int ip reset netsh winsock reset ipconfig /flushdns ipconfig /release ipconfig /renew ipconfig /registerdns After this, In the new Brave tab, type in Brave://net-internals/#dns and press “Enter” Click on the Clear Host Cache button to clear this cache. Lastly, Open Control Panel Locate and double click Internet Options icon Click Content Tab Clear SSL State. Then Restart P… You should also try turning off your vpn, closing and reopening Brave and see if that makes a difference. ---
