Okay. I have a Radeon HD 7770 and updated its drivers(new build). I'm using a Bravia Smart TV for a monitor. Motherboard drivers are up-to-date. Before, it only detected the onboard graphics(I think? AtomBIOS?)...So I updated the graphics card from the manufacturer and then PROBLEM. Rebooted, "scene selection has been changed", and then the screen was flickering and horizontal red lines across screen. Right, switched it off right away and went into safemode, and then rollbacked drivers. Now it only says Standard VGA Graphics Adapter(but it's the Radeon one, my graphic card). Right, so I tried setting scene selection to general, tried updating again and then it got worse: Static-like horizontal lines STRAIGHT ACROSS monitor, in addition to red lines and flickering. Guh. Some help please?

CPU: FX-6300
Motherboard: M5a78L-m LX V2

Cough. Adding some things:
I'm using a HDMI cable. I tried installing slightly older drivers - nope. After the flickering the screen either goes black or a completely whitish-greyish background.
Using Windows 7 64-bit. Oh, Aero theme isn't working either . It says I need to update drivers.

Okay, this is pretty obviously driver error.

Your motherboard and your graphics card both have AMD Radeon graphics chips. When you are installing the driver (Not sure if you have the motherboard driver or the Graphics Card Driver), because the technologies are similiar they are clashing with each other.

I had this similar kind of issue with a motherboard I got less than 1 month ago, from the same manufacturer as your board. I had to install the drivers in a very particular order to get the device working. The easiest way for you to fix it now is to uninstall any and all AMD Radeon, AMD Catalyst Control Center or similar drivers from your system. Try not to get the motherboard chipset drivers by mistake, just the graphics drivers. Then install the latest driver for the graphics card from the AMD website, and only that driver. Don't install the driver for the motherboard video, and don't plug anything into the motherboard video.

That is the easiest way to fix this, without several attempts with installing drivers with different orders and removing the graphics card several times in the process to figure out which way is correct.

No there isn't another way. You could reinstall windows but all that will do is remove the graphics drivers and its really the same result.

If you want to go slow with it, remove the graphics card and uninstall all drivers. Boot with the onboard graphics. Install the onboard graphics driver. Shut down, put in the graphics card, install the graphics card drivers.

If that doesn't work, uninstall all graphics drivers, and try just installing the graphics card drivers. Make sure if you do this that absolutely nothing is connected to the video ports on the motherboard.
