Computer now running smoothly
The Nvidia card decided to come back to life again so I could continue my upgrade but it still didn’t want to work in X. I found a Matrox G550 for £20 on eBay. Stuck it in last night and now everything is working like a charm. Only slight hitch was in my rush to find a card I failed to notice the card was designed to fit in a low profile case, but that was nothing that a pair of pilers couldn’t fix.
