No BIOS when bench booting

First build, and I haven't put anything in the case yet, instead I did a bench boot/test with the mobo, GPU, CPU+fan, PSU and RAM. No bios or signal on the monitor (via DVI) and I don't have a speaker that plugs directly into the mobo to check for POST beeps, although the CPU fan and GPU fans start working when I turn the power on.

I've unplugged and plugged all the components multiple times, I'm sure there aren't any bent CPU pins, I tried moving my GPU to the other PCI-Express slot, I've tried moving my RAM (1x8gb) to each of the slots, I've plugged in the 24-pin and 8-pin (on my board, there's only an 8-pin power slot for the CPU) cables, as well as the GPU cable. And I regularly discharge static onto the case.

...help please?

Remove the RAM stick/s and start the MB, you should hear beeps if the MB is ok, see how it goes.

Removing the RAM yielded the same result -- no DVI input. As I mentioned, I don't have a speaker that goes straight into the mobo.

Basically most MB's has built-in speakers for error beeps, which is different from post beeps. I have a MB (WX58BP)which has no speakers for post beeps, but if I remove RAM/GPU it beeps to warn me. And in normal condition it doesn't beeps a single time while posting.

Try another DVI cable, see what happens. But I am somewhat worried about not beeping without RAM.

I don't have any spare DVI cables lying about the place so I grabbed my TV's HDMI cable (I'm going to need to buy another one anyway as the monitor didn't come with one, assuming I get this thing to work). Still no output of any kind beep- or BIOS-wise.

1. Double check all the connections, make sure 24pin ATX, 8pin EPS, 6/8pin PCI-E connectors goes all the way or in other words fitted tightly, no loose ends.

2. Double check the CPU if it seated properly and correctly.

3. If you can : check RAM, GPU, PSU on another system to make sure they are ok.

I will be waiting for your reply, after you made all the tests. Good luck.

I tried all that but still no dice, unfortunately. And my only other computer is a laptop, which I am using right now. Two details you might want to know:

For the 8-pin CPU plug, the PSU gives me two options: an 8-pin EPSV12 connector and a 4/8 ATX12/EPSV12 connector. I'm using the 8-pin EPSV12 for the CPU as the 'shapes' on one half of the 4/8 pin don't match up to either the MB slot or the PSU manual's description: the left 'half' is made up of only the pins with cut off corners on the top, while the right is made up of those and square pins, as per the booklet and the MB slot.

And the PSU power cord only came with a weird European-style plug, so I'm using a European-to-British socket converter for the PSU.

Don't know if those two details mean anything.

Don't worry you have done the right thing, I also have that PSU and I am using a different cable for PSU altogether, so that's not the problem.

If you can : try the components as above mentioned to a friends PC, cause I want to make sure the other components are good, so you can RMA the MB.

And don't force any connectors as the manual says " Do not force the connectors into place, the connectors are "keyed" so can only fit one way." Page 9.

This is the only problem with non-iGPU CPU's, you cant try the on-board graphics of MB to make sure the external GPU is faulty, so you have to rely on another system to test. It could be faulty GPU or MB, so make sure the R9 270x is fine, and the RAM too, so that you can safely RMA the MB.

I can get a friend to test the graphics card and possibly the RAM in his own computer, although I can't get it to him until next Monday and therefore probably won't get it back until Tuesday. Should I do that and update the thread when I've found out if it works or not?

Yes indeed. We will be waiting eagerly for your post, take your time, don't hurry.

My friend tried the GPU and he says it's working perfectly (although I won't get it back from him until Monday).

Ok, then the GPU is fine for sure. Let it arrive, then install it and see what happens, if you wont get display then I think a MB BIOS update may needed.

Go to MB vendors site and look for latest BIOS update file and read the "Release Notes" of the latest BIOS, it should mention what has changed and if there is a change regarding the GPU.

Else you may need to contact a tech or service centre. The MB may need a tweak in BIOS to recognize the GPU, but you cant do that without a GPU, as your CPU/MB has no integrated graphics. Good luck.

AGESA = AMD Generic Encapsulated Software Architecture. It allows the BIOS to initiate devices on AMD motherboards.

So you can try your luck by updating BIOS. Be very careful about the updating process, read procedures carefully before you do anything, or you may brick the MB. Good luck.

An update: I was asking Amazon whether they could fix the board, and they offered me a full refund. I'm replacing it with the identically-priced Asrock 970 PRO3 R2.0, whose CPU support page (http://www.asrock.com/mb/AMD/970%20Pro3%20R2.0/?cat=CPU) tells me that the FX-6300 should be compatible out of the box.

Hopefully this should solve my problems. I'll update with either confirmation or further pestering once it's arrived and I've bench tested it with all the other components.

OK. I will be eagerly waiting for your response. From the very beginning I doubted the MB that's why I told you I was bit worried about the MB not beeping without RAM, and now I think all will be fine with a replaced MB. Good luck.

Good news! Everything appears to work and I'll pop in the Windows install disc in a minute. Thanks for all the advice, I'm very grateful.
