Welcome to the forums! you said you have tried the solutions on the internet.. the internet is a big place, what solutions have you tried?
for me the best fix is to open steamvr, then click on the drop down and choose display mirror.
then once the mirror is open, click in it and then face forward and press 'Z' that tells steam which way is forward.
usually i don't have to recenter again for a few hours.
is that one of the solutions you looked up on the internet?
