hd 6490m driver update problem

Hello, HP Support! Can you help me?
My notebook: HP Probook 4730s
My OS: MS Windows 7 64 bit

I have Radeon hd 6490m in notebook. Where can i download fresh driver for my videocard? Latest driver in your support center:     8.91-111013A-132348C (30 Jan 2012), but already 2014! I download latest driver in amd.com (13.12     12/18/2013). The driver is installed correctly, but after a reboot is not working properly. When looking for a new driver through Device Manager even after installing the new drivers, the system sets the old(8.91-111013A-132348C).

Help, please! I bought a laptop for work, but the necessary software already can not work on these older drivers ((((((
