Whilst the website advisors are not totally infallible, using them regularly you will come to trust the opinions of user's names that you will come to recognize. There is also some crossover between the two (some reviewers post on both using the same user names).
Seek advice on a forum you
trust (eg. your PC manufacturers help/support site),
Again, look for posters their with a high number of posts to their name. Should anyone deliberately try to mislead you, usually many more will put you on the right track.
As Ex_Brit, Paullotion, Grif, et al can confirm, a Moderator will never let a post offering harmful advice stand without either correcting/commenting on it, or even deleting it.
Remember , Google is your friend. There's a wealth of information out there. (not
all of it bad

wink )
