I'm running a 3 year-old Dell Dimension 2350 with a flat panel display. I haven't changed any of the hardware on it, and I (attempt to) take care of it. I don't use screen savers when I let it idle, instead I use the 'turn off monitor' option at 5 minutes. Lately, however, my monitor (or someone suggested maybe my video card?) has been on the fritz. Randomly, even when it's just sitting, the monitor goes to a completely white, blank screen. Sometimes, I can fix it by turning off the monitor for a few seconds. Other times, it takes 20-30 minutes to come back up. It also flashes white periodically when I move the mouse. Would you say this is the monitor dying, or is it the video card? I'd like to know which I need to replace. If it is the video card, do you have any recommendations as to which I should purchase?
