Having an issue with onboard graphics

[gamenerd007]

Here is my pc specs:
500 GB HDD
Win 7 64bit
8 GB DDR 3(1333 mhz)
AMD FX 6300 ~ 3.5 GHZ
ATI Raedon R7 240 ~2GB
mobo : Gigabyte 78lmt usb 3

I bought this Pc and as it has a graphics card its driver was installed (AMD catalyst 13.9)
But now i had a little prob with GPU and sent it for replacement .. in the mean time I want to activate my onboard graphics which is AMD HD 3000
The problem is I cant find its driver in the driver CD that came with the mobo and also I dont know how to switch it to the onboard graphics in the BIOS

Do I need to download the driver for HD 3000? or will my current catalyst driver do the work
PLZ help

It should be under display settings. If it says PCI, select Integrated instead.
