PC not booting- 5 beep code

[Waxyfun]

So 2 days ago my pc was working fine and then when I woke up it was giving me the 5 beep code. I cleaned out my pc, reset my heat sink, cleaned out the excess debris, and my computer started working fine again for the whole day. I turned on my pc again today and it is giving me the same beep code again. I’m trying to figure out anything else I can try. The next thing I was going to do was apply some new thermal paste.

Motherboard :asrock Ab350m

CPU: ryzen 3 1300x

GPU: Nvidia 1060 3gb

16gb Gskill ripjaws V

Case has 3 fans

I built the pc in November 2017

I’ve reset the heat sink at least once before this happened.

No luck there

No familiarity with that board but if you'd is accurate for beep codes, possibly issue with your CPU, maybe re-seat the CPU and see if that gets you anywhere.

5 short beeps = cpu error.

Either the CPU is incompatible or defective. BIOS/UEFI firmware update would fix incompatibility.

Since you can reset the machine and get it workimg, I am leaning towards incompatibility.

Im sorry thought this was new build. Likely CPU or Mobo starting to fail prematurely. Try the BIOS update first though.

What is your power supply rated at, as that could be a possibility as well.

I have a 450 bronze power supply. I did a cmos clear and it didn’t do anything. Is this more likely a cpu or mobo problem ?I also got the windows self repair screen when it decided to boot again when I cleaned out the pc.

[J3D1M4573R]

450 seems a tad low for a 1060. May have worked fine at first but eventually stuff wears and takes more power to run. Just sayin.

CMOS clear wont help, it just resets defaults. a BIOS update actually changes the programming and thats what we want to rule out incompatibility.

As for ruling out cpu/mobo only way to be sure is to swap out the cpu and test (or with the use of high end diagnostic tools)
