phantom66 0 Posted October 22, 2005 I had bought geforce 4000. When i was installing it i uninstalled the old geforce and accidentally clicked restart. After that i turned off the computer and took out the old geforce and put in the new geforce4000. Now whenever i turn on the computer with either the old or new geforce card, nothing comes on the moniter and the computer starts beeping about 20 times. How do i fix this?
