Help Please!! I purchased a new Acer desktop with Vista. I hooked up my old LCD monitor and it worked for about a week, then the screen went blank. I hooked the monitor back up to my old computer and it works fine, just wont work with the new computer. I bought another LCD monitor and hooked it up to the new Acer. It worked fine, and then about 3 days later it stopped (it works fine with my old computer). I hooked up my friends monitor and it worked fine (did not try it for extended days though). What would cause every monitor I hook up to only work for a few days? This is crazy because the monitors are all good on other computers. Any suggestions???!!
