Question about Computers & Internet
There could be two possibilities. Drivers for Video card are not installed, bad. or a faulty monitor (could be loose inside the computer) or graphics card. Another reason is because the cord that goes to the computer for whatever reason is to close to a power cord or power bar. Have you tried moving it any?
After eliminating all of these things the only thing left is the monitor itself and within the monitor the only component typically capable of producing rolling lines as you describe is the power supply.
I suspect it's the refresh rate in the monitors settings. Try making the refresh rate lower.
