My OpenSUSE LiveDVD appears to crash as soon as the blue screen appears. The logo is doing nothing at all, and the DVD drive light stops flashing. The system is;

MSI K8N Neo4 SLI Platinum (model MS-7100)
BIOS - 3.0 -
PCB version - 3.00 -
64-bit Athlon 3200+
2x1024 Mb Corsair Value RAM PC3200

Of which the mobo, graphics chip and DVD drive are confirmed as functional on the OpenSuse website.

The hash code confirmed the integrity of the .iso

I don't think it ought to matter, but the LiveDVD is written on a DVD+RW. I don't know how to test that the burn went OK, although Alcohol 120% reported that it did. I tried reburning the disc at lowest speed but get the same problem.

This is just a shot in the dark, but you might consider trying to unplug USB components that aren't completely necessary. For that matter, unplug each external device you have, then see if it'll boot. If it does, plug each device in one-by-one until you find the offender. (Sorry if this sounds too simple for your technical expertise, but I figured it's worth checking)
