That is almost certainly a hardware problem.
Most likely in the screen/screen driver, but since it also affects the outboard monitor it may indeed be in the video driver circuit.
Either case, something like that should be handled by a pro, with the mfr's repair likely being the faster turnaround choice due to parts procurement.
Or its time for a new lappy for the wife...

Mac,
You are nearer to the mark MAC I don't know how old this PC is but I would say, hardware fault and too expensive to repair, it's cheaper to buy an new PC. You can get Laptops to last years but at £350.00 for one in the UK if it last 3 year it's not bad. I wouldn't waste too much time with it.
