hi i have this weird problem. OS: Windows 7 64-bit Motherboard: ASUS M2A-VM earlier i had 1GB 667 MHz RAM of transcend which was working fine. i upgraded to 2GBx2 (total 4GB) 800 MHz RAM of kingston. but when i boot up, windows says "No audio output device is installed". to get sound back, all i have to do is simply remove one RAM so that existing RAM on my pc now becomes 2GB and sound is back! i have tried putting the two pieces of RAM in combination in yellow sockets, black sockets and yellow-black sockets. but sound is available only if any one piece of RAM is used (in any socket). i am unable to understand how RAM and sound are related!? should i update my BIOS? surprisingly, Ubuntu 9.04 can play sound with two pieces of RAM but windows 7 can't! can someone please help?

Which sound chip does your mainboard have? Please install the latest drivers."A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

Check to be sure memory remapping is enabled in the BIOS.Vote if answered or helpful, I am running for Office (joke)! IT/Developer, Windows/Linux/Mainframe I also am a true vegan and I am very good with economics and I used to play chess at 2400++

Hi, I would like to suggest you update the BIOS, the motherboard chipset drivers and the sound card driver for Windows 7 first. If it does not work, you may open the Playing Audio troubleshooter. In addition, you may also read: Tips for fixing common sound problems to troubleshoot the issue. What’s the result?

When you had only one ram socket taken with the new kingston memory unit did you also try both of the new units seperatly in that socket - to see if one of the new memory modules is defective?

thanks for your reply. i tried the same thing - BIOS update. and now it is working fine! the thing is Windows had problem when working with 4GB or more of RAM. with less than 4GB of RAM, there was no problem. BUT... a new problem! now my PC (either Windows or Ubuntu) does not recognize my iPod! i have tried everything - driver installation, iTunes installation etc etc but no solution yet. can someone please help?

the problem seems generic. this is the side effect of BIOS update. my machine: both Windows 7 and Ubuntu 10.04 dont recognise my iPod. but Ubuntu 10.04 detects a normal USB drive but Windows 7 cant. another machine (Ubuntu): my iPod is recognised. so problem is not with my iPod/USB drive but BIOS update. can anyone help in this?
