I assembled my PC two months ago without any problems. Recently it froze and now it won’t boot at all—no BIOS screen appears and the keyboard doesn’t receive power. I swapped another GPU, but that didn’t help. Added a RAM stick, performed CMOS reset and BIOS flashback, yet nothing works. All fans and AIO components stay on, but no boot screen shows. Please assist. The yellow diagnostic light stays lit for about eight seconds before everything goes dark. Specs: ROG Strix Z790A 13.7GHz, Dominator 5600 DDR5, Corsair RM850, RTX 3060, Asus Lc II, Windows 11. Image: IMG_2251.mov. Updated August 7, 2023 by RayRizz412

Have you attempted to disconnect every USB device? Does your system have a grounded USB port that might stop it from starting?

I disassembled the entire PC without any harm to the CPU. It started up using only a different GPU and the HDMI cable connected. I also tested the DisplayPort, but it didn’t work.

The keyboard is illuminated and the laptop starts, yet there’s no output whatsoever. The images captured earlier remain unaffected.

Turning off the PC and just leaving the switch on is giving USB power. The keyboard isn’t working with power, and there’s no display. I’m confused about what’s happening.

Well, if it started up properly without any connections, begin there and add one extra component to test again until it fails. First, disconnect the IConnect box to see if it’s still connected now. Check both USB ARGB and TPM signal cables, plus the two SATA power cords. When three channels are active it draws a lot of power—my setup has four and thirteen fans. I have a 1600W PSU and two GPUs, so they suggest keeping each SATA power plug on its own separate cable from the PSU, leaving nothing else attached.

red is cpu and orange is ram. I checked it with a single ram. Tried it in every slot. If it fails, I switched to another slot.
