 Topic: PC Not WorkingPosted: 08 Apr 2020 at 3:06pm |

Hi,
I have a new build that I just can't get to work. I have checked everything. The PC starts, the fans are going on the case, the CPU and GPU, and it stays on for 15 seconds, then switches off, then restarts for 15 seconds and this repeats until I turn the PSU off. What can I do next? |

Make sure your RAM is inserted in slots A2 and B2 and that you have connected the
8 pin CPU power lead to the board. The 2600 should be supported on all BIOS versions. Power cycling like that is usually RAM training, clear CMOS then power on the system and leave it on for a few mins and see if it eventually posts. |

I tried all of that. The problem remains. I have rechecked all of these connections. I checked to see if the PSU fan is working, it is. I am bereft of ideas. I left it to loop for far more than a few minutes a few times. I tried one RAM in slot B1, then B2, then the other in like manner. I feel very frustrated with this, and disheartened by this!

Ouch, ok, time to dig in:
Pull the board out of the case and connect it to the power supply outside the case. Make sure you only have 1 stick of RAM, GPU and CPU installed, no drives or other peripherals (no keyboard or mouse either). With the board outside the case you should more easily be able to see if the RAM is seating all the way into the slot. Make sure your 8pin CPU power is a 4+4 (CPU power) not a 6+2 (PCIe power) Pull the CMOS battery and disconnect the PSU from the board, leave it like this for 20mins. While disconnected from power clear CMOS again. If after all this the system still won't POST, pull the CPU and check for bent or missing pins. Good luck and let us know how it goes. |

I tell you, there's no rest for the wicked here! I did what you suggested, and took the motherboard out. Immediately I could see that the RAM wasn't in entirely. So, I enthusiastically reassembled thinking this to be the problem. I have everything neatly done, I connect the power cable and press the power button. Nothing. No fans, no lights, zero! So, I plug my phone into the case USB, it charges my phone. Everything is connected up exactly as it was before! I don't know what to think now. I am totally at a loss here.

Thanks for all your time. I rechecked the CPU and indeed there are bent pins. It's quite strange, as when looking at it from one or two sides with a torch, they didn't look bent at all! Not until I turned it completely around. Such an ordeal. It hasn't been a pleasant experience but I have sure learned a lot from the process. I contacted the seller to return it and I shall just wait and see how this all unfolds. I'll update when my new CPU arrives. |
