I looked that machine up, and it was really nice when new... <grin>
After trying Gary's advice below,
have you stripped all un-necessary "add-ins" from the "box" to see
if any of those were causing a problem? (NICs can do this),
and then reset the BIOS to fail-safe defaults?
If removing things, follow all the "static" precautions and mark
(or record?) where everything came from -- (exactly).
I realize it might be hard to get into the BIOS in your present
"condition", but some BIOSs have a boot-up key for a quick reset,
or most can be "reset" by a jumper to "default" settings.
(You would need to find this info yourself now that you know to look...)

Have you considered the MB could be going?
This starts you down the next set of long roads...

(Have you heard of the "bad capacitor" problems with some electronic equipment???)
I have had 3 Socket "A" MBs go recently in the 2002 vintage, (Non cap related),
but have had to replace other MB bulging caps, (myself).
All these MBs had a number of odd quirks before becoming VERY unstable.
I managed to find NEW (vintage) socket "A" MBs, and am using "all" the same parts
with them... EVEN my exsisting WPA (Windows Product Activation.) WinXP-Pro
installs/(HDs) since there were no significant hardware changes that seemed to bother
the MS WPA...

Disclaimer: MY OSs are "White-box-OEM" OSs, or (FPP) full retail OSs, and
used very few (if any) "on-board" integrated components that would trigger WPA
if the MB was changed.  (No BIOS-lock, no NIC, etc...)

Note that IF Gateway ties the "OS keys" to code embedded in the Gateway BIOS
(AKA: BIOS locked "invisible" WPA), then you will not be able to keep the same 
OS install if you get a MB from a different vendor. (Or at least you would need to
buy the OS again.)  This falls under the "OEM" licensing rules.

Hope this helps.
