geforce 4 mx 440 64mb sdr pci

i have onboard video. i cannot get the geforce 4 to work. i disabled the video drivers for the onboard and installed the drivers for geforce 4. but everytime i plug into the vga on the geforce it says no signal on says that the device is working but no signal from card. it did the same thing with the radeon 7000 i had before this.i have a 1.8g p4 256k with an 18 inch flat screen. i dont know what to do. if anyone can help please post here or email me at

How did you disable the onboard video?

Have you considered going to your motherboard vendor’s website for support? (This is an OpenGL forum, after all)
