Hello,
I have a Pentium 3 motherboard (iWill VA133plus) and yesterday I took it out from storage to test a processor. However, the board does not power on. Normally, the standby LED is illuminated when the PSU is connected. In my case, the LED is still off despite connected to the PSU in ON state. So due to this, I am unable to boot/post the motherboard. The voltages across the MOSFETs are also zero as the motherboard is not receiving any power.
Attached below are the images of the board specifically around the ATX connector. Could someone please share their experience with such an issue and the troubleshooting steps? Thanks.
