Clipping receiver /PC Probleme

Hi all I have a sr6011 cheap for me, I have owned top end since the early 80 ‘s but this has me stumped. It was all good for 2 years bi-amped then my pc died so I hooked it up to my laptop until I rebuild the pc and it started to clip.

Could a power issue be causing both problems?
