Hello,
I installed a new Biostar motherboard TA780G M2+ to use my Athlon FX 6000 processor. It will not post or show any display. I've replaced the PS, the DVD drive and tried it with both onboard video and a PCIe card. I also tried my old DDR2 5300 RAM and a never used OCZ DDR2 6400 stick. I still can't get any display or splash screen. All lights come on, fans spin, SATA drive spins, but nothing. Any suggestions? I've built 4 other computers w/o any major problems, but this one has me stumped. Thanks!

This procedure seemed to resolve the problem (after pulling out the MB and 'breadboarding' the system:
>6. Have you tried booting with just one stick of RAM installed? (Try each stick of RAM individually in each RAM slot.) If you can get the system to boot with a single stick of RAM, you should manually set the RAM speed, timings, and voltage to the manufacturers specs in the BIOS before attempting to boot with all sticks of RAM installed. Nearly all motherboards default to the standard RAM voltage (1.8v for DDR2 & 1.5v for DDR3). If your RAM is rated to run at a voltage other than the standard voltage, the motherboard will underclock the RAM for compatibility reasons. If you want the system to be stable and to run the RAM at its rated specs, you should manually set those values in the BIOS. Many boards don't supply the RAM with enough voltage when using "auto" settings causing stability issues.

I started trying one known 'good' stick of ram in each slot. On the third try, it posted. I was then able to set the Bios and continue. The system seems to be working fine. Thanks!

Hello pgullion and everyone,

I know this issue is solved but it is worth to share that I had this same problem but it was related to hardware failure. I found one of the capacitors near the memory bank that was damaged, it was a 1000uF 10Volts. It had a little bump on the top instead of being flat. I replaced it (kinda difficult if you dont have the right tools and skills) and voila! The board is running again. The cap heats up so I guess it could be a desing problem and probably it would happen again so this is helping me to do a sys backup and think of migrating. I did all this because it was out of warranty of course, otherwise I would had replaced the board
