[SOLVED] PC weirdly goes into a rapid on/off loop

[ReDust]

Hi everyone!

My rig seems to randomly restart rapidly in a loop after a few seconds I turn it on, almost like flickering (led flickers along with the sudden fan noise ramps and each lasts between a few hundred milliseconds to a few seconds). Sometimes it successfully loads into Windows before entering the loop, sometimes it won't even post and just go straight to the loop. I don't think it's a cable problem since it seems to always finish a post after removing a component/shuffling the ram, then it starts the loop after.

Here's what I've already done so far:

• Reseat ram and gpu
• Recheck cable connections
• Cycled cmos battery
• Boot without gpu, ssd, and all peripherals unplugged

EDIT:
All 4 ram slots are occupied.

SPECS:
CPU: Ryzen 3 1300x
Mobo: Asus Strix B450-f
Ram: G.Skill TridentZ RGB
Drives: Samsung 860 evo + WD Blue HDD
GPU:Asus TUF GTX 1660 Super (3 fan)
PSU: Cougar VTX 600w
OS: Windows 10 Pro

Attached clip shows booting without gpu, drives, and ram:

Any help will be deeply appreciated.

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list them like so:

Can you get into the BIOS for your motherboard? As for the rams, please mention which slots they're populating on the motherboard.

Hi, thanks for the response! I've edited the post accordingly.

I can sometimes go into BIOS but it just randomly enters into the loop shortly after so I can't really do anything within it.

Try a different power cord.
If no help try a different wall socket.

Sometimes Bios is confused because it can't recognize or read your SPD (Serial Presence Detect) and so goes into a loop trying to train your RAM for a safe set of Timings and voltage. It will do this 2-3 times then attempt a boot or shut down.

Your G.Skill modules will have a Part/No printed on the modules or packaging.
Similar to F4-3200C14D-16GTZR. Please list to check for a mismatch and what can be done.
You may have to alter or set Timings and voltage manually in Bios.

Already did, and I even tried to plug it with and without an AVR to no avail.

I tried booting without a ram and it won't even finish the memory error beep sequence. Same goes without the gpu and drives. It's like flickering interrupting the beeps.
I'll still recheck and list the ram though as you suggested, thanks a lot!

Unplug all disk and disc.
Use one stick of ram in the proper slot.
Power up and try to enter the bios.
If you can get into the bios let it sit to see if it will fail.
