Cant install drivers, MUI-file?  

When trying to install my Sound Driver, by right clicking on PCI-device(theres nothing else, and that must be the sound.) it installs, but at end comes up with this error:
The resource loader failed to find MUI file.

Its a High Definition Audio-controller im trying to install, since theres nothing else. I tried to install other windows 7 drivers from the web, but i run the setup, reboot, and nothing happend. I tried most solutions, i searched for many days now, i really need my sound back.

ye, i deleted it, uninstalled, rebooted, tried most standard solutions. my specs from dxdiag under the tab system:

Okay.

Install the latest bios:
MSI Global ? Mainboard - P55-CD53

Make sure HD Audio is enabled in bios

First thanks for helping me, but still no sound.

Theres still a PCI-device, yellow marker and the code 28, cant install drivers. I use live update 5 right, i install the realtek audio drivers, restart pc. Nothing new, when i go to the device mananger, right click on pci-device, update driver, theres only high definition audio and when i install that, i get the code 28 resources cant read MUI file.
BIOS: Ms.7586 VERSION 1.00

When trying to update to 1:B0 I get an error, press key, PC restart, nothing new. I dont get whats wrong. I hope you can help. :)

If you are having problems flashing your bios with the Live Update, then try the following:

Sorry, i dont own a USB drive, on 1 gb or more. Are you sure this will fix my sound problem? I dont understand what flashing my BIOS does. Its only my sound not working, and i just gotta solve that my resources cant read the MUI-file. And flashing my BIOS should do that? Arent there other ways?

Sometimes, when a device is not recognized, an update in the bios will find it. I personally have updated a bios, after which the computer reported new device found. Not saying this will definitely be the solution, just one possibility.

Okay, any other solutions? My windows 7 is for some reason not activated, and my disc is gone. I still have the product key, so i install a windows 7 copy off the net. U know a good place? I will install it, then use my product key.
