Thanks for the help guys. The problem was : I had an old copy of XP service pack2 & the computer only had SATA drives in, so without the update to service pack 3 it was a no go. Got a good copy now on disk for future. installed easily and worked first time. BUT
Well after 4 weeks of trying to get the Dell computer to run for more than 30 minutes. I change back to an old system that was 10 years old, It ran consistantly, all programs installed even touch screen. BUT! cant get the drivers for the sound card anywhere. So no good there
. I switched back to the DELL and after changing memory, hard drives, formatting drives re-installing from scratch, removing and cleaning heat sinks and fans.and it still did not work for more than 30 minutes. I was just about to throw it in the bin when I thought I'd just check what google has to say, after watching videos on how to remove the capacitors from the mother board, researching what capacitors were needed. I nearly gave up. but then after pages & pages of google hits was a little message "it could be the cd/dvd drive" Now in my head there was no way this was related, but what had I to lose by trying it was going in the bin anyway. So I unplugged the cd/dvd drive completely and started it up..........
Low and behold it has been running non stop for 5 days...... apparently its a known fault with certain dvd drives on DELL computers, but they like to keep it quiet. So all good now, the finish line is in sight & people want to hire my jukebox out from me! but I wont do that it's for me & my family for fun times at home.
Keep on building people. Thanks for looking
