Im working on a new build so I put everything together and have no display. To try to single out the problem I tried a different case, psu, and ram but no difference. Tried both VGA and HDMI with no display.(No graphics card)(Tried on new monitor & projector)

I only have the motherboard, psu, ram, hdd & processor hooked up so as to isolate any problem. Without the hard drive I still dont have display but it doesnt post and beep once.

Heres a video.

And heres one without ram.

Already RMA'd the motherboard with newegg and have the same result with this new one... Any help would be greatly appreciated.

Motherboard: Asrock a55m-hvs
Processor: Athlon x4 631
RAM: 4GB Pareema DDR3-1333 10600 CL9
PSU: Rosewill 400w LC8400-BTX

The Rosewill is the other PSU. The original is part of a case/psu combo. Sentey BCP450-OC (250 Watt Constant /450 Watt Peak)

Try removing the cmos battery with the power to the computer disconnected. Let it sit for 5 to 10 minutes and put the battery back in, and then plug the computer back in too. It will clear the BIOS of any settings that might be messed up.

I don't believe 5 to 10 minutes is enough time for the CMOS battery to clear. I usually leave overnight.

Left the battery out for well over 24 hours. Now no beeps at all, not even the 3 long beeps with ram removed. I think I'm going to RMA for a refund and go with a different brand.

Lol surprised no one caught it.. Cpu without on board graphics requires standalone graphics card apparently... makes sense

Good one. :)

Tried both VGA and HDMI with no display.(No graphics card)


This was a little confusing though. You said no card, it had no onboard graphics either...so one would wonder where the VGA/HDMI ports were (on a typical board)? It would have also helped you identify the problem (no where to plug in the VGA cable).

However, turns out your board does DUAL VGA (vga+hdmi) which is why it has a provisions for the same.
