Hello everyone, i'm new to these forums although have been browsing through them for the past few months, just haven't needed to post until now. I installed Windows 7 (Build 7100) on my desktop pc as dual boot with my already existing Windows XP. Both operating systems are on different hdd's so there shouldn't be ANY conflicts at all from the previous OS when booting Win7. Before i begin with posting all the info i found, here's my system specs: Intel Q6600 Asus P5KR Mobo (Using the onboard Realtek AC sound card and onboard Atheros L1 Gigabit Ethernet Card) 4gb Ram Nvidia 8800GTS 512MB 4x HDD Windows 7, Build 7100. 32bit. Antec 1000w PSU After the first use of windows 7, all of my drivers appear to be working fine besides my NIC. I figured since Win7 detected my nic as the correct one, and had installed it's own drivers for it, that this problem at hand was just a driver related problem relating to the one which came with Win7. So i tried updating the drivers multiple times with newer and newer versions each time. To no avail, my NIC is STILL not working. (The most recent driver i installed was 22.214.171.124 from the Atheros support site which has Win7 32/64 bit support) The error code i get for my nic in devices manager each time is : "This device is not working properly because windows cannot load the drivers required for this device.(code 31)." I have also Updated my BIOS to the most recent version, as well as re-downloading the newst versions of my NIC drivers from the manufacturer & vendor web sites. I also have reinstalled Win7 3 times now just incase it was a bad install issue, though this was not the case. Another side problem i've now also got... is when i try boot back to my WinXP OS it essentially loads like normal to a certain point (xp logo load screen) and after that is slows down to loading about 1/100th the speed it was before until it just freezes after about 5min. I have tried loading XP in safe mode, and this works no problems, although when i try load XP in safe mode with Networking, it freezes when trying to load all the drivers before intiializing safe mode.. related to my current problem maybe? Any help people can give would be GREATLY appreciated. Thanks!!
