Question about Biostar : NF4ST-A9 Socket939/nForce4/DDR400/SATA/ATX Motherboard (MOTBI15)
PSU and case switch proven good with back-up mobo. Pressing case switch functioned only intermitantly until yesterday. VSB is 4.56VDC, PS_on reads 0.748VDC and does not go up when switch is disconnected. Shorting PS_on to ground turns fans on but does not post the CPU. Reset has no effect. I am wondering what could be wrong since I am leaning towards Motherboard due to a different issue where the onboard nic would drop connection all the time. Motherboard is less than a year old with no overclocking.
A 6ya expert can help you resolve that issue over the phone in a minute or two.
