sounder CD 6 reboots PC

[Matthew Parslow]

I just tried to install sounder CD6 onto an older duron (SCSI DVD, IDE
HDD, gf2mx) 
immediately upon booting, (so quickly that you can't see if anything's
loaded) it restarts the system. I tested an old debian CD I had lying
around and it booted successfully. I'm currently grabbing CD 7 and I'll
try changing the video card tomorrow for a G400
in the meantime, any ideas would be welcomed
Cheers,
Matt
