No audio devices are installed (Fujitsu) and

Hello,

I searched before asking but none of these solutions helped me.

Three days ago my Fujitsu Siemens Pi 1536 suddenly crashed - the screen went crazy and I pushed my laptop's power button off. Then I turned it on and everything went okay - then I realized I have no audio drivers anymore. No sound, nothing.

- 'No audio devices are installed.'

- Windows can't detect a problem or automatically update.

I tried to reinstall them (Realtek) but this didn't help me. Tried every possible way to make things work. Uninstalled them; reinstalled them; installed them over the old ones; disabled and enabled... Still nothing.

Of course, after that I decided to reinstall my Windows 7 (clean install). I never had problems with installations until now. I boot from DVD and it loads the files, but then black screen comes with a cursor and restarts after 3 seconds. So it's kinda a restart loop. Burned Win 7 on five different DVDs - none of them work! It's the black screen with cursor over and over again. I thought it may be a problem with my Graphics. For example it can't change resolution or something but I don't know how to resolve this. I know these DVDs work because I tried them on my other laptop and they start with no problems.

So I still can use my laptop but there is no sound. And I cannot reinstall my Windows. I'm stuck and I'm going mad now.

Do you guys know any solution? I'd be sooo thankful!
