Ok i'll try to make this simple as i'm in a hurry lol.
Bought my pc about 5 years ago and it came with XP home. Used it on that pc with numerous reinstalls until 2 months ago when i got this pc. Installed it on here thinking it wouldn't work due to it being OEM (i assume since it came wiht the comp). Tried to activate it and it worked to my surprise, didn't even ask for the code that's on the sticker. Used XP fine from 2 months ago until today. 2 Days ago i took out my graphics card because it needs to be RMA'd. Put in a new temp card also 2 days ago, ran XP fine. Suddenly today XP is saying it needs re-activating due to hardware changes.
Tried to do it online as i did when i first built this new pc, but it says the activation code has been used too many times so I need to get a new one. If i call them, what can I say, i mean I guess i'm not supposed to use XP on this pc anyway due to it being a new build. Does it sound like i will have to buy a new version of XP?
Cheers,
Chris.
