All that said, don't worry, I think I have killed it now

I decided to take bits of it apart to see what could be upgraded, starting with the RAM (says 16MB DIMM on it) and then the HDD, which I took out and disconected - says Toshiba 2167mb on it) Put it back together, booted up and now it won't boot up

It has always run on Win98, so I bunged in the Win98SE set up disk and boot floppy, but it only gets 5mins into set up and says extended msdos failure or something and shuts down. Tried installing from the Win2k boot disks but it says "unexpected memory" something or other and shuts down

Fuck

Bet there was some half decent stuff on the HDD I have lost now aswell
