This sounds like a hardware failure (or interoperability problem). I
would try the following:

1. Check if it responds to the Magic SysRq (I would bet it won't, but
you never know). If it does, you at least get a bit more information for
troubleshooting.

2. Try disabling hd dma, or at least try different dma settings. This is
the most probable cause for this kind of behaviour.

3. Run a full memory check with memtest86.
