Power chords are suddenly weird

Hello all,

Suddenly couple power chords started sounding weird, kind of out of tune.
I already tuned all strings but when I play those power chords the sound does not look the same.

Positions :
D---2----
A---2----
E---0----


D---5---
A---5---
E---3---

etc

I appreciate your help, I am total begginer

Thanks

You're probably still out of tune.
When you play the chord, the 6th and 4th string should be exactly an octave apart so that's the first thing I'd check.
And if you don't have an electronic tuner, now's the time to get one.

Thanks Schmange,

I have an electronic tuner and it seems the strings are tuned.
However since you pointed out that the issue is associated with the strings, I will double check.

I was wondering that maybe there was a battery issue but I think this is not the case.

Thanks again. I will double check and I will let you know

Yes schmange. You were right.
After couple tests with my electronic tuner I realized my E string was a little out of tune.
I fixed it and evrerything is back as normal.

Thanks again
