Problem: So, got all the parts connected to my new machine, and ... nothing turns on. I have this motherboard. If I plug the motherboard into the PSU, the MoBo's back LEDs come on. If press the case power button, nothing happens whatsoever unless I lay the computer down so that the weight of the motherboard is on its back, then if I press the ON button, the case lights and the lights built into the RAM chips turn on. But still no POST and none of the fans kick on, including the PSU fan. If the PC is standing upright, as its supposed to, it wont turn on unless I ever-so-lightly press on the motherboard, then I hear an audible "click" and the case lights turn on, and again, no fans or POST and no video out anywhere...(and in this case I don't even have to press the case power button) I've checked behind it and I don't see any screws or anything that could be causing it to short out anywhere. Is this something that can be fixed, or should I RMA it? Hardware: Mobo: ASRock B550 Phantom Gaming-ITX/ax AM4 AMD B550 SATA 6Gb/s Mini ITX AMD Motherboard Memory: G.SKILL TridentZ RGB Series 64GB (2 x 32GB) 288-Pin DDR4 SDRAM DDR4 3200 GPU: GIGABYTE AORUS GeForce RTX 3060 ELITE 12GB Harddrive: Intel 670p Series M.2 2280 1TB PCIe NVMe 3.0 x4 QLC Internal Solid State Drive (SSD) SSDPEKNU010TZX1 just this plugged in atm, once it POSTS I'll plug in some SSDs from my previous computer PSU:CORSAIR SF750 CP-9020186-NA 750 W SFX CASE(if it matters): SSUPD Meshilicious CPU:AMD Ryzen 7 5800X - Ryzen 7 5000 Series Vermeer (Zen 3) 8-Core 3.8 GHz Socket AM4 All parts are brand new, except for a few SSDs which I haven't even tried to plug in yet. I've tried Removing the MoBo from the case, placing it on an anti static mat, and it still doesn't post. Doesn't even have the RAM LED lights turn on. Also I've installed a new motherboard. and it ALSO WONT TURN ON. If you plug it in, the motherboard LEDs turn on, but it wont turn on if I click the ON button, nor will it turn on if I sort the power switch pins. No other LEDs turn on, no fans, and no attempt to POST. How can both boards be duds? I've also tested the 24-pins on the PSU according to this guide. All the voltages are good, and the PSU seems to be working. The Atomic Man-Boy fucked around with this message at 07:30 on Feb 21, 2022 |

Zogo posted:Try using only one stick of RAM and disconnect all non-essential peripherals like drives and keyboard/mouse etc. Tried that. Took it out, placed it on the foam mat it was shipped in... and nothing. The problem is that without whatever short I might be creating by pressing down on the board, it won't do anything close to turning on. The second problem is that even when it does turn on, I don't get a POST or video or fans. Third problem is that even if I do get it to POST, I might need to to reach in and tap it every time I want to turn it on.

Yes, but the new board has those little QLEDs that show you the status of the bootup. They go BOOT -> VGA -> CPU -> DRAM. If it stopped at a certain stage, I could go off that information. But none of them light up, it doesn't appear to even try to start up.
