I have a Microsoft surface pro 7 approx a year old. It crashes once or twice a day when I'm using it as a tablet. I took a photo of the fault. I've looked it up but I'm not happy to repair it myself. This is what the screen says Stop code: PFN_LIST_CORRUPT Can you advise, give me a quote I'm sorry to ask but I will need a quick turnaround. Kind regards Ian Goddard
