Do Gateway machines use ATX, or are they on some arbitrary thing so they can screw you out of more money by making you buy one of their PSUs?
I put 512 MB of RAM and a 9800 Pro in mine, and I think the weakness of the PSU is causing stability issues. (I originally had 256 MB of RAM and a MX440; now 768 and the 9800Pro.)
