Hello I recently installed new RAM in my PC and it worked perfectly fine but I noticed I wasn’t getting the megahertz that said on the box so I went into the BIOS and changed it to 4400, but once I did this I got the 3 beeps and had to go into the BIOS again because the POST failed and I did this process a couple of times until I set it to 3600MHz and then all of a sudden this happened to my PC. The picture will be down below but there is no beeping or anything can you please advice me on what to do next? I will also link the specs of my PC and the new RAM I installed

The RAM is not appropriate for your CPU, AMD state here up to 3200MHz/MT/s and if you have DOCP/EXPO/XMP enabled the RAM will get auto OCd past what the CPU can handle and the PC will become unstable.

Okay I understand thank you! Any ideas on how I can fix my PC? Because as it stands all the fans and the lights come on but the heat sink fan doesn’t spin and no signal coming from the PC to the display so what can I do or is my PC just done for good?
 
Have you checked that the CPU cooling fan connection on the header on the MB has not been disturbed.

Did you ground yourself before touching the insides of the case and likewise was the PC disconnected from the mains outlet and the residual charge drained out by holding the case power button in for twenty or so seconds;

If you have not been messing with stuff inside of the case I would be at a loss to explain what has happened.

The CPU is powered by a separate 12V ATX supply from the PSU, has it been disturbed somehow, check it at both ends.

Make sure that you have a keyboard connected at all times.

Fwiw, you will not get anything on the screen if the PC does not attempt to boot.

Can I ask that you do not quote every reply as we have to read the full post to make sure nothing gets missed,, thanks.

Yes I have checked and made sure it was secure and it is. I have made sure to take the charge out by pushing the power button for 30 seconds and yes I grounded myself. I have just installed the new RAM that was it, but I will have another look around the PC to make sure the cables on the motherboard are secured again. Do you suggest I put in my old RAM? Since you say the new RAM I got is not appropriate for my CPU.
 
Polite reminder;

Needlessly quoting posts is not only annoying and unhelpful it also gets detected as spam and needs approval before it is visible on the forums, please desist with the quotes.

Changing the settings to 3600MT/s in the BIOS would not cause this so need to ask if anything else has gone on.

You do not mention having a keyboard attached, thi is a must else the power on self test will fail.

Do not do anything inside of the case for now.
 
Apologies I was just hitting reply on the message didn’t realise it would make a mess of things.

I have had a keyboard attached yes I’ve done everything you’ve mentioned. So what would you suggest I do? I can open the case again and make sure that all the cables are plugged in, maybe resit the RAM? Other than that idk what else I could do. There is an amber light underneath my GPU that is on beside the bottom PCI slot could that mean when I was fitting in my RAM my GPU could’ve been detached a little? Would this be a reason as to why my fans are going except for my heat sink? The LED lights around my heat sink are all working it’s just the fan that is not turning.
 
Part of the below will clear any bad MB settings including disabling any OC so don`t worry about putting the previous RAM back in.

The following checks require the computer case to be opened so take the following safety precautions 1st, disconnect the power cord from the wall socket, press the case power button for twenty seconds or so to get rid of any residual charge in the system, take anti static precautions before touching anything inside, you can do this by touching a bare metal part of the case or PSU or if a notebook by touching a household radiator or associated copper feed pipe.

Remove the CMOS battery from the MB.

Remove and then reinsert the RAM making sure that it is nice and snug in the slots.

Repeat the same procedure as the RAM with the GPU + additionally make sure that the supplemental power dongle from the PSU to the GPU is securely attached.

Check that all internal fan and PSU to MB and hardware connections are secure.

Put the CMOS battery back in.

When all of the above has been done, connect a keyboard, the screen and the PSU to the power outlet then power up with your fingers crossed.
