My home server has been experiencing instability issues running Debian stable.

My issue is I have no sound output and overnight the computer will

I updated to 2.6.38 thinking it might be a kernel compatibility issue
but the problem remains.
I downloaded and booted from an Ubuntu 11.04 CD and the system has
been running stable over the last 5 something days.

Ram has passed countless passes on Memtest86+, The CPU i'd have
figured would have failed running any OS.
Likewise the system is stable running Win 7 64bit.

I have attached an lspci -vv and lsmod.
I have a feeling that my issue might be Debians firmware stripped
kernel but don't know where else to look for problems, dmesg dosen't
seem to provide any hints.

So, before upgrading the kernel to 2.6.38, where you using the standard stable Debian kernel (2.6.32)? If not (but seems yes), maybe downgrading the kernel back to the stable one is a good thing to test.

Maybe this is still a hardware issue (typically bad electrical contacts) you have temporarly disabled because of physical manipulations on the machine. So, I encourage you to retry Debian and see how long the uptime can be. Of course this test may require several days...

Another thing, have you see any kernel oops (Call Trace, etc.) in the logs?
Did you try to unload kernel modules you might have installed recently?
