My Acer 5730 Travelmate came preloaded with Vista Home Premium. But after a system crash, re-installed Vista on one drive and Windows 7 on the other. Now 3 months later, Vista system properties shows 'activate Windows now'. But despite numerous attempts am unsuccessful. Vista System seems to work fine except at reduced speed. Device Manager window shows a completely blank window with only menu bars showing. Also Add New Hardware not working. In Network Connections, my LAN connection is not showing, where one can see the sent and received bytes. Sorry if this is the wrong place to post. Please kindly bear with a noob and any/all help would be greatly appreciated. Thanks kweeny.
