I have a video card in it since 3 yrs ago,I turned the computer on and the manual on my new tv said to increase my resolution for a better screen,So i did and then that is when i lost everything.When i reboot the computer up now all i get is a grn screen with nothing on it.I am able tp right click and click on properties where then i could change the resolution if the properties would open up but it dosen't the mouse hour glass makes a little movement bit then quits, and im back to a plain screen.Thank you
