Help!
Shut down and disassembled my old system due to faulty pice connections.
So purchased new b250 mining expert mother board with new cpu and new ram. Reused ssd, put it all together and booted it up and .... nothing. Nothing on the screen, screen goes to sleep waiting for signal. Not even had the bios come up.
What do I do, currently not mining with 8 cards whilst problem persists.
Double checked cables are connected correctly.
Any ideas would be greatly appreciated

Even in the event that an attacker gains more than 50% of the network's
computational power, only transactions sent by the attacker could be
reversed or double-spent. The network would not be destroyed.

Check to see what the output is in the bios of the motherboard.
If it is onboard switch it to pcie adapter as main display output.
You will need to have an old monitor to connect to it so you can bring up the bios on screen first.
You probably have the monitor currently connected to one of the gpus so you will not receive any signal on the screen if the onboard adapter is active in the bios.

I have now unplugged all the gpu’s, with only screen in mother boards HDMI port, and screen is in HDMI setting. And bios won’t appear on screen??? |

Do you just have a single "A" supply hooked up at the moment?
Do the PSU and CPU fans come on?

I agree sounds like OP just isnt connecting video up to the current settings. Put a GPU in there and boot up. Wait 10mins. and then try plugging into GPU for video. If that doesnt work then reboot while hooked up to onboard video.

try everybody elses recommendations , also make sure the RAM is reseated specifically. and P4 is in P4, and atleast in MOLEX connected to on board MOLEX. If you have 4+ cards, connect the seconed MOLEX as well

Yes all fans come on and stay at a low rpm, on gpu and cpu. Have only one power supply on A and another hooked up supplying gpu’s with just power. With paper clip mod. |

So to confirm, plug gpu on to board leave for 10 mins and then plug in hdmi? And I should get bios? If not with gpu on board re boot with hdmi connected? |

Clear CMOS (AKA Reset BIOS Settings). I'm sure that will solve the problem. If you don't know how to do then google it.

try to re-seat the CPU. you can also plug in a beep speaker to hear the bios beeps.
Reseated the cpu, tried removing one stick of ram and swapping them over etc. Nothing yet, brand new PSU 750w. Still no post? Sounding like mother board is broken? |

Also, remove the SSD. Just the PSU, Motherboard, CPU and RAM connected to a monitor. If it still didn't boot, seems like you're right, yes it's broken. Most B250 mining expert threads here and from external forums consists of faulty ( little to few problems) b-new Mobo that were suggested to be replaced. But before you RMA that board, can you tell us the CPU model that you've bought together with the Mobo, was it a 6th or 7th gen intel CPU? And what was the previous Motherboard that you've replaced by this? |

You can try the PSU in another computer or use PSU tester to see if it is working correctly. If it is, it probably is something wrong with your motherboard.
Also make sure that the CPU is compatible with that board, only LGA 1151 is compatible with the B250 mining expert. These are the immediate things to check as if you had a bad RAM you would hear beep-s. I think though that the board may be DOA (dead on arrival).

I think his b250 mining expert was gone to junkyard today, It's funny to see that many people here posting their comments on the post they didn't read well. It's September 2020 today. By the way one of my B250 mining expert is the same problem with you dude.  |

This being an open air rig, you never bothered hooking up the Audio PINs to the basic Speaker located on the computer case correct? Where the pins are for the RESET and POWER ON and LEDS etc there are some pins for the Speaker. You need to hook this up to some computer case speaker.
Then when you power on the computer, it will beep and the amount of beeps will let you know what is going on. I had this issue before. Hooked up an old computer speaker. It beeped a certain amount of times and let me know that the RAM wasn't fully in the slot. So I reinserted the ram and it finally booted.
