I installed Windows 7 Pro 64bit on a 2 year old computer with a Gigabyte EP45-DS3R motherboard and an Intel Quad Q9450 - on a new hard drive. I have actually installed a Windows 7 Ultimate 64bit as an upgrade from a Windows XP Pro also on this computer.
Every time I turn off the computer, I lost internet connection. The only way to get it back is to turn off the computer, unplug my ethernet cable, let it boot up completely, and then plug the ethernet cable back in. Then everything works! And this happened on both of my Windows 7 installation.
Any idea how I can solve this problem?
Finally figured out the root of my problem by process of elimination. The problem disappeared after I uninstall the Photoshop and Acrobat CS3 from my computer, apparently there is some internal conflict.
