Hey everyone, about 3 months ago I bought a legit Win7 key from the web. Windows activated fine and passed every WGA test, online, offline, you name it. Today, after coming home and having had the pc idle for a few hours, it all of a sudden shows as not genuine. It also doesn't pass the online test. What could have happened and how might I solve this - expect by modding my bios and being done with it..?
