Here's an odd one: Dual boot XP and 7 150 with 512MB. If I reboot to XP from 7, I have to reboot again to get WiFi card recognized. Subsequent boots are fine, just the first from 8 to XP. (Oh, and if I boot to 7 with power connected, same thing) Secondly, at my parents place, various websites are inaccessible from XP (yes, I did do the double reboot thing before you ask), such as anything M$, including updates, ebay and others. They were accessible from 7, and from XP again after returning home. Weird!!!
