The Pc did seem to be overheating a bit during DVD encoding, but I’ve not done any of that and it’s been fine since. Maybe the heatsink needs re-seating?
I’m now running on StartCom Linux, this a vaiation of RedHats’ Fedora Core 6 that I was using. I didn’t have any problems with FC6 but I didn’y have the disk handy when I needed it so I thought I’d try SC instead. There’s not much to tell between them.
It’s a bit slow to boot but that’s due to my unusual SATA/IDE setup, I’ll resolve that eventually but I’m in no rush at the moment.
