Thank you very much bjk.
Issue of the ATX 12v connector now solved. CPU now up and running. LED's OK too. The RAM (512mb) was ordered with the board - Kingston I believe.
Problem now is that it all boots up to:
"Disk boot failure - insert system disk" which she or I don't have. I am familiar with the term but beyond that..........I have tried booting from the ME disc but nothing happens.
Checked the BIOS and CMOS and all seems OK.
Questioned my daughter about the crashes she had and it seems that she thought she had viruses of some kind! When starting there is a very unhealthy noise from either the floppy or the HDD. I am considering formatting it on my machine and start again and then perhaps I can boot from my XP Pro disc once it is clean.?
BTW. I have acquired a simple graphics card but cannot connect it until the system is OK.
I confess to being at a bit of a loose end at the moment.
Sorry.
