Tighten your tuning knobs, they might be loose causing the strings to go out of tune. Also replace your strings every 3 months if you play everyday. I personally like DR Strings, they stay in tune and play great. Plus last long if you take care of them. Also check your neck, it might need adjusted. Same with the guitars intonation. I would take your guitar to a professional guitar repair shop and not Guitar Center for those jobs.
