Okay, i've got a HP pavilion 7855, It has a Intel 810 chipset with onboard VGA. I have a new game that requires my color to be at True Color 32 bit, but on my display options, all i have is True Color 24 bit, I thought it was my video card, so i bought a 32mb ATI Radeon 7000. I have looked all over the internet and followed about 3 guides to do this, but nothing ever works. I know i need to disable my on-board video card, but i have no clue how. What I did was delete the driver from the device manager, then shut down my computer, then i put the new card into the pci slot, and i plugged the monitor into the new card. When I started up the computer, it goes to the HP screen, but it wont do anything else, it doesn't finish booting, and it doesn't let me get into BIOS. Any help would be appriciated.
