Hi geekstogo, I've got a problem that has kept me busy for quite a while.. and I could really use some help.

First of all, some of my specs:

- Asrock z75 pro3 motherboard; Intel HD Graphics 4000 (onboard)
- AMD Radeon HD 7800 Series (dedicated)

What I want: I would like for my pc to only use my dedicated graphics, and never the onboard ones. However, I can't get this to work.

What's happening:

- My pc recognizes both adapters and is trying to use Virtu MVP in order to use both at the same time. For those of you unfamiliar with the program, basicly whenever I try to start a game/program that's recognized by Virtu MVP, it'll switch from my Intel to the AMD graphics. This seems to fail me for quite a few games, which is why I'd like to turn off the Intel graphics all together.

Why I cant fix this myself:

- I've tried changing bios settings from onboard to PCI-E and plug my monitor into the dedicated graphics card -> Black screen.
- I've tried disabling my onboard adapter in Windows, restarted pc, plugged monitor in onboard -> uses onboard. Plugged monitor in dedicated -> Black screen.
- I've tried uninstalling all drivers, disabling onboard adapter, unplugging dedicated card, setting Bios to PCI-E, shut down pc. Plugged in dedicated card, same thing as above.

Basicly whatever I try: Either; I get a black screen and I'm forced to unplug my dedicated card alltogether to force my pc to use onboard graphics -or- it uses onboard graphics automaticly.

Remember: My pc does recognize the graphics card and I have played games on it before, I've just never been able to actually get visual by plugging my monitor into the dedicated card.

Thank you in advance, this is killing me.

Hello Endiction, sorry to hear of your problems. This kind of thing can drive a person to drink, been there done that.

This should not be happening with modern motherboards; your board should automatically detect the insertion of a 2nd party video card and auto-shut down the integrated video. 20 years ago or so you would have to enter the BIOS and manually disable integrated video, but every mainstream board manufacturer that I know does this automatically now. The fact that it is attempting to use both and will not function unless the integrated video is running makes the board suspect. Hopefully the board is still under warranty, so if it is contact Asrock (or better yet, return it to the retailer) and file an RMA request. Don't ask them what they think, get aggressive and tell them the board is faulty.
>As a last-ditch attempt, reinstall the mobo drivers, but I don't think that will fix this.
>Double-check your Radeon driver installation; if there is a config panel installed for the card there may be some type of config setting for this, but I don't put a lot of hope in that. I am sure you did this already.
>Try removing the card and installing it in another box (maybe a good friend's?). See if you have the same problem, if so, the card is suspect.
I only built one unit with an Asrock board several years ago and had severe problems with the USB ports, any time I plugged in a USB peripheral device the system crashed. Finally I flashed the BIOS and the crashing stopped, but there were a couple of ports I couldn't use because anything plugged into them glitched and wouldn't work. I never used an Asrock board since then, always used Asus and never had a problem in all my builds. Of course, that is no guarantee for the future. :rolleyes:
