I have not tried using CPU-Z. I did not try and load all the drivers included with the wireless card because I cannot find a vista cd. I have lost mine. Could you please tell me where I can find this disc. I had went to best buy and spent $80 on a upgrade they told me that was all I needed but I guess they were wrong. I did do the upgrade but it did not solve my problems. The only thing it did was let me run windows 7 now along with my problems.
