Problems after installing windows 7 64b

[RainyNights]

Had windows 7 32b before but wanted to upgrade them to 64 because i had 8 gb ram and it was going to waste. After installing 64b the system says that all the drivers on my pc are up to date but my resolution is so low and i have no audio devices.
Tried using my drivers from windows.old but i wont do anything.
My specs are :Cpu amd fx-4300 vishera
Ram :8gb dual channel dd3
Motherboard:Gigabyte 970a-d3
Graphics:16MB ATI Standard VGA Graphics Adapter
Optical devices:TSSTcorp CDDVDW SH-224DB ATA Device
Audio:High Definition Audio Device

Go to Gigabyte website and download their video drivers for your motherboard model since it looks like you are using built in graphics card. May as well grab the chipset drivers while there too.

Also, check AMD's website for any drivers for your CPU.

Done that fixed the resolution issue but the sound issue is still there.
Tried getting the drivers,installed em but device manager says that my ATI HDMI audio works fine and my VIA HD audio works fine als😵n sound i cannot find any device.I suspect the problem is that my windows audio wont start (it says error 1067).

Which version of that motherboard do you have? There are different audio drivers for different versions, were you able to find the ones you needed on Gigabyte's website? Looks like either VIA or Realtek drivers are needed.
