Sound too loud and distorted

I see a power supply but not an answer to my question. I don't know what the machine had, I can guess this is what it has now. And it's strange to need all those formatting codes in your reply.

Try headphones to tell if it's the PC or the amplified speakers.

I did not upgrade my psu.I have always used this one, thought that it would suffice.I have tried different headphones and the problem is coming from the pc.

I have a Corsair TX 750W V2

But if you see what details you provided, the clue points to power supply first, then motherboard troubles. Most folk try a sound card first as it's cheap. Then again if the power supply is overtaxed all bets are off.

Thank you for the quick reply Bob. I think the sound card test may be the solution to this problem. My guess is that the integrated soundcard cant simply handle it anymore. I've read around in different forums about integrated soundcards vs dedicated soundcards, and the majority say that dedicated soundcards are more resilient and the audio quality is much better. I also found people that had the same issue as me. Their audio was distorted and a dedicated soundcard fixed that.

I will add a dedicated sound card to my motherboard and see if that helps.
