It's a Gigabyte GA-8S661FXM-F... Intel P4 HT Prescott 3 GHz installed, along with Kingston 1GB PC3200 DDR400 RAM and a Fujitsu 20GB IDE HDD.
I've tried a Sparkle 300W PSU, an OKIA 300W PSU and a Delta 500W PSU, and tried different memory combinations with a Apacer 512MB PC3200 DDR400 RAM module. Only sometimes will the computer properly POST and continue on to boot the current installation of XP on the hard drive. Most times, it will be in an "infinite" restarting cycle without any POST or display.
When it POSTs properly, the CPU heatsink properly feels warm, as well at the HDD and the RAM. When the machine is in its "infinite restart" cycle, the CPU does not run, and neither do the RAM or HDD.
I also believe I have cleared CMOS, etc...
What is the problem here... try more power supplies??
