Problem with new PC setup: it fails to power on despite correct components.
Problem with new PC setup: it fails to power on despite correct components.
The CPU is Ryzen 5600G, the motherboard is B550M-K. (Verified compatibility.) The GPU is RTX4060 (the graphics card was removed temporarily.) The power supply is 800w. I’m wondering if installing an operating system is necessary; I’m certain the PC needs to power on at least before doing so. No OS is installed yet.
Following the title, the CPU cooler spins very slowly and I can barely notice it. The case fan also spins extremely weakly—it’s almost imperceptible unless you pay close attention. Pressing the power button again yields no response until I switch the PSU to 0, back to 1, then press the power button once more; it rotates just once.
My motherboard has an orange light in the lower left corner indicating power is active.
What I attempted:
- Disconnected all cables from the back of the PC and set the PSU switch to 0, removed the CMOS battery, pressed the power button for 5 seconds (repeated for 5 minutes), then reinserted the battery and reconnected everything—PSU to 1 and power on.
- Removed RAM sticks completely and tried pressing the power button with only one stick in place.
- As shown in the photo, the PSU connector is connected, the PSU or CPU power is linked to the top right corner switch, the CPU cooler fan is connected, front panel power button is linked to the power switch, CHA_fan2 is connected for case fans. Switching the PSU to 1 made the orange light appear briefly, indicating a short.
- Standoffs were perfectly installed; all screws are securely tightened (8 total as specified).
- For the CPU cooler, I had to tighten each screw gradually, as doing it one at a time would cause it to float in mid-air.
- The CPU processor checked for matching arrow/triangle markings and was set correctly, but I lifted it to confirm—no movement.
- The PC power cable is plugged directly into the wall.
- At this stage, removing the motherboard would take an extremely long time; I’m certain it was done perfectly.
PSU - 800w
What is the model and make of the PSU?
Did you breadboard the setup before placing it in the case? This is typically done to test the system outside a motherboard enclosure, checking if it starts up and displays properly.
It would be quick since a faulty BIOS might either leave no display after powering on or cause the fans to run continuously without showing anything.
It's a foreign product though, I wonder if it helps.
Brand - FSP
Model - HP2-800
Do you need a breadboard before installing the motherboard?
I installed the CPU processor, then the CPU cooler, and finally the RAM.
After that, I had to put the motherboard in the PC case to continue.
Asus is listed in the supported options, but your system must run BIOS version 2403 or higher for compatibility. You may try the Crash Free Bios feature to potentially upgrade to a newer BIOS that supports the 5th generation CPU. If this isn't possible, you'll need to consider a third-generation CPU or an older model to update the BIOS accordingly.
What? you checked and it's actually not compatible? So I got it right but it's just not compatible until I do the crash-free bios thing? I don't understand why they didn't put a huge red capital letters to notice it then. It was already sad it's not a B550M-A for rgb when I have rgb. bad luck and need to know all ways too much 100% perfection to get it right. Damn beginners should never build on their own. lol It does say 3rd gen cpu ughh. Only if it didn't say it is compatible on the website or something. It's the 5th gen and I don't know why they bother to sell 3rd gen. I don't even have an extra pc now. As if this usb thing is easy thing to do to begin with. So I guess the problem is found? Can I use a smartphone and buy something that can connect USB with phone and download the bios update?
It's an older chipset, when the third generation was released it was out, and by the fifth generation it wasn't even made or available in stores. The BIOS update won't function on this board without a third generation CPU. Crashfree only works if the CPU is recognized and you can access the BIOS.
