Dont press so hard.
Dont say youre not.
99.9% of new starters do, I can practically see it from here!
Get your guitar,
Touch a finger onto any sting, on any fret, just behind the fret. Dont press it down. Start picking the string. It should sound like a dead thunk. Now, very slowly, start applying more pressure, pushing the string down while picking it. When the note sounds clearly, add just the tiniest shade more pressure; thats how much pressure you need.
Any better?
