i tried deleting the .minecraft folder and reinstalling minecraft and nothing happened. i reinstalled java but it still keeps on crashing help anyone please

Your computer probably isn't fast enough.

Probably bad graphics card/drivers, try getting a DxDiag report and share it here

Mine has 4GB, Still gets 80-107 FPS w/ OptiFine. Also, you may need to update Java. If not, delete and re-install your Minecraft by going to %appdata%, and deleting the .minecraft Folder. Then login to minecraft.net and redownload it. Hope that helps
