[SOLVED] PC doesn't boot. Mainboard outputs 5 beeps and red VGA, Boot status LEDs are on.

[questionUser]

Hello,

I tried building my own PC. My specs are:
CPU: Intel Core i9-10900KF (no graphics unit)
Mainboard: Asrock H570M Pro4
CPU cooler: Noctua NH-D15
RAM: 4x Crucial 8gb ddr4-2400 udimm
GPU: GeForce RTX 2060
Storage: Samung SSD 1TB and 240GB

After trying to boot, I can hear 5 beeps through the mainboard speaker and the status LEDs for VGA and Boot on the mainboard are glowing in red. All RGBs and coolers are running, but nothing appears on the screen. Researching this does lead me to the assumption that no graphic unit was detected, even though my graphics card is installed correctly (its coolers are running). My HDMI cable is connected to the graphics card. After testing it with another graphics card which resulted in the same error, I can confirm that the card is not broken.

I appreciate all responses on how this could be fixed.

With the psu unplugged remove the lithium battery from the mobo, we'll both are removed hold the power button on the case for 30s x2s then repeat battery then psu cable. Boot pc

What's the make and model of the PSU?

Test with bare system outside the case. Cpu, cpu cooler, motherboard, one memory stick, GPU and PSU and try to boot to BIOS.

It's a pretty bad configuration. A motherbord that hold up the cpu https://www.techspot.com/article/2252-intel-b560-disaster/ (H570M Pro4 has the same VRM) and dramaticly slow RAM.

PSU: 650 Watt GameMax NT 80+ Bronze.

And is 2400 MHz RAM really that bad? From what I've heard it only makes a small difference.

That's bad.

Up to 20% FPS compared to 3200 - 3600.

Ok, so what now about the PSU? Is this the reason why my system can't boot? Your statement doesn't really help me.

And I only play less graphically advanced games (rarely), I only need much RAM to be able to host multiple virtual machines. So that shouldn't be a problem.

It's not the amount of ram that's a problem really it's the speed especially running vms

Psu isn't a quality psu and actual is known for failing not to say yours is dead for certain but its likely a bad psu

I've worked with 2400 MHz RAM in the past and never had any problems with games or VMs. There surely is a performance difference, but I think "dramatically slow" is greatly exaggerated. Furthermore, I think it's not subject to my question.

Thank you for this information. I've used this exact PSU in my old PC just 2 days ago and never experienced problems with it. In my new system it doesn't appear to be malfunctioning, considering that the RGBs and all fans are working properly.

Unplug both disk.
Use one stick of ram in the proper slot.
If it still fails you have less suspects.
Next step is move the mobo out of the case and onto a piece of cardboard.

I don't know where you quoting ""dramatically slow"" from ve never said it was like that however main question I do have for you is were the 2400MHz sticks you used at the time paired with a ryzen or Intel 10th Gen or newer?

Ok, so what now about the PSU?

Bad quality, bad performance. That PSU has 2 fake 12v rails, 22A each and one OCP for all rails. Multirails only make sense if each rail has it's own protections. One of the 12v should go to CPU, ATX and sata/molex. Only de cpu can consume up to 20A so there is almost nothing left for the rest. That PSU has a bad configurated platform that's not sufficient for your system.

Your statement doesn't really help me.

You tried

Test with bare system outside the case. Cpu, cpu cooler, motherboard, one memory stick, GPU and PSU and try to boot to BIOS.

already?
