Hello, i have just installed a radeon HD 6450 now my pc is confused as to which card to use radeon or on-board. i haver disabled the on-board graphics but for some reason no matter which vga connection i use it always starts up on the opposite one despite the on-board being disabled. now i am totally confused, how can i fix this?

Uh, if the cord is plugged into the GPU card, then that is the GPU being used by the system. Make sure latest drivers are installed for new card and maybe even uninstall the drivers for the onboard card.

Switch to the pcie vga in the BIOS, remove graphics drivers for it, install graphics drivers and be sure you are connected to the graphics card-not the motherboard.

well gents, i have gone through each of those settings but still it continues to act the goat and reverting to onboard graphics.
once windows has loaded if i hit the reset button it will then go to the radeon6450..

That's an interesting one.

Like ittimjones says, make sure your monitor is plugged into the discrete card, if your monitor has the option of 2 inputs disconnect all others.

Everything else seems right. Is your BIOS up to date?

From wikipedia:
Quote:
PCI Express 2.1 supports a large proportion of the management, support, and troubleshooting systems planned for full implementation in PCI Express 3.0. However, the speed is the same as PCI Express 2.0. Unfortunately, the increase in power from the slot breaks backward compatibility between PCI Express 2.1 cards and some older motherboards with 1.0/1.0a, but most motherboards with PCI Express 1.1 connectors are provided with a BIOS update by their manufacturers through utilities to support backward compatibility of cards with PCIe 2.1.


Your mobo is PCIe 1.0 and the card is PCIe2.1
Going by these specs

So that might be the issue
