No sound with 4GB memory on the laptop
I have an Compaq CQ40 Laptop and today I changed the memory from 1GB to 4GB but after upgrade I do not have sound at all even if the hardware is ok and fully functionally. I took one af the sticks and put the old 1GB stick and is working Now the problem is when I put both 4gb i do not have sound but with 3 GB I have. It is anything what I can do to make the Windows 7 64-bit to have sound with 4GB memory?
Thank you!!
