Thanks for all your help. But I'm shrecked, arn't I?
Sadly I can't tell him I was mugged as he was sitting next to me when his computer went FUBAR. I coughed and told him it was a temporary reverse. He was quite sweet. Said that if he left it off for a day or two and switched it on again that it might work (It's not dead, it's only sleeping).
When I got the blank screen and cursor after boot up, I tried control+alt+delete. There were 4 processes running, one of which was explorer. I had hoped by ending that programme it would stop the hang, but no such luck.
The irony of all of this was that I had an old win 98 cd and boot disc but threw them out in December (I'll never need these again - ha, ha, ha).
Even if I do get into the puter using DOS, I have no idea which files need to be restored to get Win 98 working again. If those files have been overwritten by IE6, then I'm really shafted.
Where do I find a bloody Win 98 cd rom and boot floppy in 2003? The British Museum?
I'm fast begining to think that the only way is a reformat of the hard disc and bringing my dear father in law into the 21st Century with XP.
Perhaps he'll forgive me the loss of the data on the basis that he has a zippy new OS.
Ah well.
