Hey all, I recently just bought the parts for my first pc and assembled it all. When I go to turn it on, the case fans, cpu fan, gpu fan and LEDs all turn on but nothing shows up on monitor. Specs: CPU: Ryzen 5 1600 Motherboard: ASRock AB350M Pro4 GPU: EVGA GeForce GTX 1060 6gb RAM: Crucial 8GB kit (4gbx2) CT2K4G4DFS8213 PSU: Be Quiet 500W BN241 If you need any others let me know. Few things I've tried: -Sent back the motherboard and got it replaced -Sent back the graphics card and got it replaced -Sent back the RAM and got it replaced -Tried breadboarding Notes: -Yes I have the 8 pin CPU power connector plugged in. -Yes the HDMI cable is plugged into the GPU and not the motherboard -Yes the monitor works (tested it with a laptop) -Yes I have the RAM sticks in A2 and B2 -Yes I have the 6 pin power connector plugged into the GPU One thing I've noticed is that every 30 seconds or so all the fans turn off and on again and there is a small buzzing noise. Not sure what that is. Any help is greatly appreciated. |

If you tried bread-boarding and already replaced all items,that leave CPU and RAM compatibility.Tried swapping with another CPU,and place single stick RAM on each DIMM to see which slot kicks in. Oh and be Quite is multi rails PSU,if you can find another single rails PSU such as Seasonic,Super Flower or Corsair you might give it a shot. |

| " rel="nofollow - Thanks for the help, will try these things out. Surely it doesn't matter if the PSU is multi rail or single rail though? |

Please stop wasting the store's time and money because you have no clue what you are doing! Just sending back random parts is not proper troubleshooting. |

In my case here http://forum.asrock.com/forum_posts.asp%3cTID=6603&title=fatal1ty-ab350-gaming-itx-ac-rx-vega-56" rel="nofollow - here ,when I switch HX750 from default multiple rail to single rail,my system are able to boot the GPU.Well it might not specific to yours because i had a power hungry GPU,but you did everything except PSU,right? |

Single Rail = One high AMP 12 volt power circuit, this one rail accounts for most of the PSU's Watt rating Multi Rail = 2 or more lower AMP 12 volt power circuits, if only one rail is attached to the GPU it is often not enough. The cumulative power output of these rails accounts for the PSU's watt rating So what this means is a 600w dual 12v rail PSU is in fact only as powerful (on a single rail) as a 300w PSU. In this instance even a 400w single 12v rail PSU would be better for your system. If a GPU has 2 power connectors then you can somewhat compensate by powering each with a separate rail (load balancing). In a situation where there is only one power connector on the GPU, you are out of luck. Multi rail PSUs are typically not ideal for gaming/GPU centric systems, they are most useful in servers, small silent systems (multiple rails make for a cooler PSU) and office PCs. This is a non issue with high output PSUs (+1000w) but anything sub 700w can be problematic, more so the lower you go. Now I am not saying the PSU is the problem, just explaining why it is important to use a single rail PSU in most gaming/GPU intensive systems. That said, the PSU could certainly cause post problems.

As for your problem, check the following: 1. Check the CPU and socket, make sure there are no bent/missing pins and no conductive material fouling the pins. 2. Check the underside of the board for conductive material (some thermal paste is conductive) or gouges, anything that looks out of place that could be causing a short. 3. Try another cheap stick of RAM, one from the board's QVL, if your RAM is incompatible with the system it causes the exact symptoms you are experiencing. If the cheap RAM works then you can update your BIOS (please use instant flash only, it is safer) and try the original RAM again. If all the above does not help, try another (single rail) PSU. -------------
