Diagonal walking

[ReaperOcelot]

So, when I get into game for about 1-5 minutes my game starts to force my character to walk diagonally (Forward and left) and I've used 2 different keyboards and nothing has helped. I've tried running it in specific modes with a tech friend and it's still not working..
Any help? Thanks.

Does this happen in other servers? Or in singleplayer?

Single, multi, it's like the W and A keys are being held down but they aren't.

I've also tried un-installing and re-installing and it doesn't seem to help.
