Windows 7: No sound, no video via HDMI

Windows 7 ultimate 64 bit
No sound, no video via HDMI

System was working fine until earlier in the week. Turned it on and nothing via HDMI, no sound and no picture. I didn't change anything, honest! In Control Panel/Devices and Printers, the Pioneer VSX-1124-K is there, shown as Pioneer AVR 2014. When I go to Control Panel/Hardware and Sound/Sound, this is what I see:

What I should be seeing is this:
No sound, no video via HDMI-sound-should-.gif
What I'm seeing in Device Manager for Sound, video and game controllers is Realtek High Definition and High Definition Audio Device. Sorry but I don't have a screen print of it.

When I go to the Intel Driver Update Utility, it gives me this even though these two there now are the current drivers from Gigabyte's website.

***Update*** I downloaded and installed the graphics file from Intel and now Sound looks like this:
No sound, no video via HDMI-sound-currently.png

And Device Manager looks like this:
No sound, no video via HDMI-device-manager-now.png

I should be able to see the receiver in Sound but I can't. It's like Windows isn't seeing the receiver when the system starts. Can anyone tell me what's going on and how to get it to work again?

Thanks so much in advance!!!

The system (Video) is not seeing the HDMI cable plugged in. That could be a fault on the motherboard, a fault in the CPU's video section or reinstalling the Intel video drivers may fix it.

I had a problem with onboard video on a Gigabyte motherboard. It had DVI and VGA connectors for on-board video from the Intel CPU. The DVI port died on the motherboard and I had to use a separate Video card (which wasn't a bad thing as I got much better video from a separate video card - my Windows video experience jumped from 3.2 to 7).

Well, I figured it out and it wasn't the computer at all. Turns out one of the inputs on the receiver has died, which would explain why the computer wasn't seeing the receiver. I did a system reset and, for the moment at least, has resolved the problem. Thanks for your input, Fireberd.
