Help Me play MC [resolved]

Hey Guys,

So I don't really know what forum to put this under but I have been having trouble playing minecraft. Opening it up works fine but when I try and open up a world or even try and log into the server minecraft will crash on the loading screen and then close itself after a min of waiting. I'm on Mc 1.12.2 and it has always worked before but now it does not and I have no idea what to do. Any help/ideas would be appreciated.
Thank you.

Try uninstalling and re installing minecraft, I honestly have no clue why this would be happening.

Does it give any sort of error/log files?

do u have any mods installed?

Have you tried turning your pc off and on again?

Something I had recently: I tried overclocking my processor more (!) but didn't have time to properly test it, and though a 10 minute stress worked without issues, Minecraft crashed after a while, and then eventually immediately too, and then finally ended up blue screening... Turned the overclock back from 4.6 GHz to 4.4 GHz and all was fine again.

Thanks for the advice trying that now I'll check later see if that works

Nope nothing like that just once it's at the loading screen it goes white then crashes.

Just Optifine.

Yes

Good to know

Ok Uninstalling Mc and reinstalling did not fix the problem I still can't laod up my minecraft worlds or log into servers

So turns out I had a bunch of Viruses and just had to clear them all then restall mc again and restart my Pc. All good now Guys thanks for all suggests.
