I just bought this re-conditioned emachine from tigerdirect.com and it has worked great...till about a week or so ago the monitor will not come on. i tried another monitor and nothing happened, and i put both monitors on older computer and worked just fine. i figured it is the onboard graphics card but i do not know what graphics card to buy that will fit and work properly. i have found some on ebay but do not know if they are compatible. I dont need anything super fast just want it to work same as the old one. It says it has NVIDIA GeForce 7050 Integrated. Thank you
