keyboard not registering keystrokes to boot to DVD

Specs: Windows 7 Home Premium, Intel i3 G3220 3GHz / 4GB DDR3 RAM
This is my mini HTPC i built a few years ago. I've just noticed now some issues in WMC that if won't play any files in the video library. Tried several methods to fix this, but no joy. So decided to do a fresh install of windows 7. Now this when i reboot the PC the message comes up 'Press any key to boot from CD or DVD..' i press a key and nothing happens, tried several keys, but it doesn't register for some reason. Keyboard works to enter into the Bios. The motherboard is a Asrock H87M-ITX and the usb configuration is:

USB Controller - Enabled
Intel USB 3.0 Mode - Smart Auto
Legacy USB Support - Enabled
Legacy USB 3.0 Support - Enabled
USB Compatibility Patch - Disabled

Also to get into the Bios, can't do it from a cold boot. Have to restart the PC from the start menu and they it registers keystrokes. And sometimes the PC just hangs at the Motherboard logo screen or the cursor _ on a black page for half a minute. Other times it boots into windows in 10 seconds.

How many different DVD's did you try? Are you sure that the DVD that you are using is bootable? Have you booted another machine with it?

Just curious. Have you ever been able to get the keyboard to work in BIOS from a cold boot?

DVD player is not the problem, tested and working. Can't remember if the keyboard ever worked from a cold boot. I would say when i first built it and installed the OS it worked, as didn't make a post then.

I've managed however to get boot off the DVD. Did this by disabling all boot devices except for the DVD; then after the first part of OS install, added the HDD back to the list of bootable devices. Working fine for now, as not needing to get into the bios again.

There is however that issue of the the PC hanging on bootup on the bios screen for about 30 seconds. But since its a HTPC, 99% of time it boots up from sleep. So don't see that problem very often i can live with it.

Strange that you had to disable all but the DVD drive, as this implies it was booting to something you disabled, which clearly shouldn't be the case if the DVD was set to first. Oh well, computers can do some weird things at times and glad to hear you got it sorted (more or less).

Go back into the BIOS & check the boot sequence.

Boot sequence was setup correct, just when get this screen 'Press any key to boot from CD or DVD..' it doesn't register any keystrokes from keyboard. So only way i could get it to boot to DVD was to disable all other boot devices so PC had to boot to DVD without needing user input.

The fact that you had 'Press any key to boot from CD or DVD..' means that you had only gone for the "one off" use of the CD/DVD drive first. There is almost always a way in BIOS to change the sequence of all drives semi-permanently, then it would have booted to the disk without requiring any keyboard input. It all makes sense now, as does disabling all the other devices as the way you worked around it.

I don't see any other option there, 1st boot device i selected optical drive, 2nd device was solid state drive. even pressing F11 and choosing optical drive, it still asks for me to press a key to boot to it.

The boot sequence is not the issue, something else in the bios or the motherboard itself might be faulty. Due to it hanging for 30seconds on startup sometimes, and keyboard not working.

OK, it's just that many BIOS's have temporary and semi-permanent settings often in quite different places within the menu. I guess yours does not. As BIOS is "effectively" hardware, actioned before Windows starts, then I agree that your keyboard and hang-up issues have to be either BIOS or motherboard.

I suppose you could see if there is a BIOS update that corrects this, although I would be surprised if such basic things have been missed. If these issues were not experienced in the past then its update state is not the problem. As you probably know, there are risks associated with BIOS updates.
