Thank you, I don't feel confident at all opening up the case. I find it odd how the past two days it's been absolutely fine, including gaming and then on a PDF document scrolling it was when the error occurred. I did install the latest Nvidia driver update yesterday, could it be related to that? If it happens again I will revert back that driver and then send it off to the manufacturer. Cheers.How comfortable do you feel about opening the case? At this point, I really think you should look for liquid damage. Look near the vent, obviously. To clean any corrosion found you will need isopropyl alcohol and a toothbrush.
Look up the Adamant IT channel on YouTube for instructions and advice.
