My dad has a nividia geforce graphics card in his computer and a 22 inch benq lcd monitor. Everynow and then when he starts the computer(its becoming more frequent every day),the computer screen is black and when you turn it on it says no signal.even some times when its left idle it does it.I'm guessing its a problem with the graphics card.Ive done all the obvious steps like clean the graphics card, make sure the screens plugged in and update the drivers.
Does anyone know what could cause this??
I will put the specs of dads computer up tomorrow
