Windows 7 no sound
Hello everyone! I've recently bought a Medion Laptop which had a Windows Vista OS. Because I'm not a big fan of that OS, I've installed Windows 7 Ultimate/32 bit. After installing it, I had no sound or wireless connection. I've fixed the wirelless connection (hardly), but still couldn't fix the sound. And thrust me, I'm no begginer at this. But, since I can't fix this on my own, I'm asking for your help. My laptop model is Medion MD96370 (also says CM2 above that writing), motherboard is WIM2170, Serial Number from bottom of my laptop is SN :30007436. I've tried everything, I've searched and instaled\desinstaled a lot of sound patches and other fixes, but with no results. In the right corner where I should adjust the sound, still shows "x" on audio cone and says "No Audio out put device is instaled". Everest versions show no audio device as well and in device manager shows no audio device either.I've even upgraded it's BIOS, but still no results. If anyone could help me, I would be verry gratefull. Thank you in advance.
