If the system worked fine before replacing the PSU then there has to be a connection between the new PSU and this problem. Are you sure the data cable and power cable for the hard drive are firmly connected to the hard drive and motherboard? If you can get to the boot menu, run system diagnostics to be sure the hard drive has not failed. If the drive passes then with F12 select the hard drive to boot from (it may be Windows Boot Manager). If that works then in the BIOS the boot order may be wrong.

Thanks for info.
I ran diagnostics yesterday. No issues.
Boot sequence shows item 1 onboard SATA hard drive - not present.
2-4 seem ok.
Item 5 - onboard network controller not present.
No hard drive ... I'll re-check that connection.
