Problems with my Motherboard/Graphics card combo

I recently bought a GIGABYTE GA-MA78GM-S2H w/ integrated ATI 3200 HD graphics card.

The mobo works fine while running onboard.

But when I want to use my 8600 GT 512, it will only run SOME games.

The lower end games like Runes of Magic or Titan Quest will cause my computer to do a hard reboot.

No BSOD, as I have already turned off the "automatically restart" feature in Windows.

Any ideas? Should I buy an ATI card to fix this problem?

What Windows version are you using? Are your games fully patched, and are you using the latest version of your display driver?

I'm more concerned about what your video driver situation is...

It sounds like you might be trying to get these to 'co-exist'; when you added the card, did you uninstall the 'on-board' drivers completely, before installing the card drivers?

In the BIOS:

On the "Advanced BIOS Features" page:

"UMA Frame Buffer Size" to "Auto"
"Init Display First" to "PEG"
"Surround View" to "Disabled"

On the "MB Intelligent Tweaker(M.I.T.)" page:

"PCIE Clock (MHz)" to "100", not auto - auto sometimes doesn't work properly...

If you want to use the Hybrid Xfire, this is the only option; trying to get an ATI and an nVidia to work together is like putting a snake and a mongoose in a box! If you will be happy with the performance of the nVidia alone, with a bit of fiddling, it should work fine...
