Boot problem

[stuff]

I have a homebuilt pc with a Gateway Brookings motherboard. I upgraded
several components for my nephew (HD, DVD-R, video card). Upon
completion it worked great, except I noticed that the onboard sound
isn't working (sound card has the yellow exclamation point in W2K
device manager). After trying various drivers, I tried installing
WinXP and sound still doesn't work so I conclude the onboard sound has
a problem.

Since I have 4 more identical motherboards, I try swapping out the
motherboard. Now, I get the bios boot screen then a flashing cursor.
Try all sorts of things, reseat CPU and memory, switch memory in the
two slots, unplug various devices to the bear minimum, no change in
boot problem. I switch out to another motherboard, same problem.

Any suggestions on nature of problem when the bios boot screen appears
normally, but gets stuck on a cursor just afterwards? I tried booting
to a floppy, but no go, same problem.

clear the cmos on the boards.......make sure the PSU is up to the task.
The drivers for some integrated sound chips must be installed from the
maotherboards install disk. Once the original drivers are installed, the
updates will be able to be installed.
