I have an acer aspire x3200 Monitor says no input signal (go to power safe mode) I was only able to use computer in safe mode The computer was on (power safe mode) for two weeks. The monitor is ok with another desktop I tried with a different monitor, same message (monitor goes to power safe mode) Why is this happening and if it's my video card probLem will I be able to replace the video card and solve it? It's currently using GeForce 8200 The NVIDIA® GeForce® 8200 motherboard GPU provides DirectX® 10 and HD movies to everyone. System is Windows Vista™ Thanks
