Thanks for those links and your assistance Gerry.
I have a few things to do now, so will get on with those and see how things go.
I have previously connected to the HP and Intel sites and ran their update utilities, but never had any of these updates come up in the results.
I had an idea my bios was out of date when it was mentioned in the event log when I looked yesterday, but have not ever updated a bios so was a bit wary of looking into that knowing some downloads and advice online can be inaccurate (to put it mildly).
I am ever so grateful to you and team ZigZag for helping, but unsure of the etiquate regarding Kudos. You have both been very helpful so far so should I give kudos to all replies?
regards and thanks again
