I have just experienced a day of getting my crippled laptop back to life again. It's no fun when you are trying to meet deadlines
and fix your PC!
Eventually I had to resort to reinstalling XP - and my troubles went from bad to worse! XP refused to activate and promptly logged me off every time I tried to log in. It seems that because I had recently replaced both the motherboard and the hard drive, Microsoft refused to believe I was the legitimate owner of the XP license.
At least to its credit, Microsoft was able to fix the problem over the phone, but it took some time and a lot of numbers were involved.
Ah Microsoft, you've done it again!
