Problem with PC startup looping and failing to post.
Problem with PC startup looping and failing to post.
I am assembling a PC for a friend and encountering some posting difficulties. As shown in the video, the DRAM light is yellow, the CPU light is red, and the VGA light is white. I have conducted extensive research on this issue and tried various solutions as outlined below.
What I've Attempted:
- Resetting CMOS
- Placing RAM sticks in separate slots
- Using different PCIE slots
- Connecting HDMI and DP cables
- Thoroughly checking each component physically
- Verifying all power connections
- Updating BIOS via USB Flashback
- Switching to different M.2 slots
- Reinstalling the entire system twice
- Installing GPU on a separate machine (it worked)
It remains stuck in this cycle until I shut it down. Once it reaches the white VGA light, the fans start increasing slightly as if attempting to post. Any assistance would be greatly appreciated.

It might seem a bit odd, but it could actually be quite effective. I ran a virtual test bench with these specifications and it was delivering 673 Watts into the system, which is why the 650-watt PSU wasn’t performing well. I’d suggest using something in the range of 700 to 750 Watts instead. This issue occurs frequently—when we build a new system, turn it on, and it fails to POST because there wasn’t enough power initially. It’s frustrating, but worth considering.
It's actually a 700W unit, yet I'm still experiencing the same problem. It keeps looping the QLEDs.
How long have you left the system doing that. I recently did a New Build test redux via OCing everything to Max & it took at least 20 minutes for me to get a responsive POST from the system so....................maybe it's doing a MemTest Config or something. This is also why I use ROGs' Maximus Mobo cuz they have Q-Codes to indicate the problem if ever lol . . . consider if ever to switch CPU brands to Intel as this is also why I don't use AMD anymore . . . I'm also sponsored by ROG too and they highly recommended towards me that Intel is a better source for troubleshooting these new days as Q-Code Mobos are the new thing lol . . . helps out a lot of problems . . .
There's no possible way that PC would pull anywhere near 673 watts during boot. Seemed an odd recommendation.
Anyways, have you tried re-seating the CPU?
I should note that when it reaches white (VGA), it sounds like it's very near the end. Just no display and the cycle continues.
