PCV-RS720G Sony Vaio : BFG 5500 installed and wont display

Model : PCV-RS720G - Sony Vaio Tower

Here's my problem, i just recently installed BFG FX5500 into the tower and when i first restart the computer and plugged the monitor into the new graph.card , it had a Red Sign on in the middle of the screen that read,

Attention signal Frequency is out of range
H : 44.8 Khz
V : 85.4 hz
Please change signal timing

I have done the steps by disabling my Intel(R) 82915G/GV/910GL Express Chipset Family , Display adapter after plugging the chip in and then restarting computer, to where i have got that "out of range" on the screen.

The problem with the monitor showing the "signal timing" would occur after the logo, but to explain the problem even further, the display would only show on the Intel Display Adapter.. to the point to where ilogg in. -- before i logg in, i can see my cursor on the Nvidia Display Adapter -- after i logg in, i get the whole screen Without Any Icons.Although, i can browse through the computer. No games or apps are able to run exept window folders and IE . I basically had 2 screens because i would have to periodically switch the cord to the monitor back and forth with the Display Adapters . That occurs when either i have both adapters enabled, or just the Nvidia enabled.
