Hi Nic
Things have moved on again! I tried doing the driver deletes again, failed and had a go at updating the BIOS. Despite following the instructions on the Asrock website as carefully as I could, I obviously made a botch of something because I killed the PC. W8 recovery started and failed. Eventually, I managed to get the 'troubleshoot' menu and all that offered me was a 'refresh'. That worked to the extent that the PC was alive again but all my programmes were lost although my personal files were not. Four hours later I was back to where I started but with one gain. The graphics card shown was the basic Microsoft one and I did a full download from scratch from your site now confirmed with 3062 shown as the applied driver.
So far no 'FtRes/Rec' messages and no freezes. Unless I get one or the other, I think I'll leave well alone.
