This would be a first.
Having trouble getting on line, sometimes it works, sometimes not. Now it wont work at all! Modem & Router OK so I removed and swapped the the Ethernet card from 2nd computer on LAN. On start up Windows Genuine (dis)advantage recognised a hardware change and has invoked a 3 day limit on revalidating the system. I havent got a clue where my original disc's are as it came pre-installed.
What do I do ?
