hi, my son has just replaced his psu, cpu, motherboard etc in fact all parts since his last psu blew up all his parts, everything new, he has new psu and its making buzzing noise and windows 7 is freezing on shut down and having to manually turn it of, not sure if theyre related but any advice would be welcome, i think they diff issues and the psu could just be a noisy one but with last one blowing up hes worried as made a similar but noisier electical noise, new one is a seasonic x650 thanks Jo x

Update your drivers, firstly.

And check in safe mode if it freezes or not.

Troubleshoot the issue by putting your computer in clean boot state (selective startup) and check if the freezing reappears or not. Some 3rd party app or startup item might be the culprit.
