My Dimension 8100 now starts up with the blue screen and NO_MORE_IRP_STACK_LOCATIONS. This is apparently a BIOS problem. I did upgrade my BIOS several weeks ago as advised by the XPSP2 instructions, using a BIOS upgrade from the Dell site.

 

I cannot restart my computer, in any mode.

 

Should I get my older BIOS back - if so from where? I am lost here.
