Black screen after installing patches on new computer

Dell Precision T1700
ATI Firepro 2270 video card
Redhat 6.5

After patching the computer and rebooting, the screen stays blank. I tried CTRL + ALT + backspace and nothing. I tried factory recovery and then unselecting the video drivers but still the same. I do get the POST screen but once it starts to load the OS it blanks out. I tried taking out the video card and booting up with the onboard video. It says i915 0000:00:02:0: More than 8 outputs detected. Is there anything I can try to fix this?
