Gateway GM5084 mb: C51GU01
ram: 4×512 DDR400
System boots with 3 mem slots occupied, but not with all 4 (total freeze before XP splash screen)
Individual sticks test OK with Memtest86+.
Also, system will occasionally freeze after several hours with 3 sticks installed. Board temps show normal in BIOS. Can’t do any tweaking with this bios.
Suspect PS issues. Maybe?
