i have a Dell Optiplex 390 w Win 7. It was fine but would not load flash for Farmville. It ran on my Optiplex 550. Other pages played flash. I reinstalled OS. Now I cannot get the internet. I am hooked up with an ethernet to my laptop. I also have a Edimax Lan Adaptor. It will not load drivers. It did before. I have tried uninstalling and installing, done ipconfig etc. I have tried to install programs through the flash drive but keep getting installer integrity error. I was able to install a fully installed CCleaner through the usb, ran registry, still nothing.
