Hello to everyone,
I just build my first pc the other day. Everything seems to work just fine, except for the turning on of the PC. When I press the button to turn on the PC, everything turns on(Fans, rgbs...) except for the display for a good 10sec. In that 10sec the power button blinks white and than it just starts normaly. If you need any kind of info I'll be glad to tell you. Thanks for anyone taking their time to answer my question.
Config:
CPU: AMD Ryzen 5 7600X
GPU: RX 7800XT
RAM: 32GB DDR5 5600Mhz
Mobo: ASUS Prime A620M-K
PSU: Cooler master 700W 80+ bronze
OS: Win 11 Pro 64-bit

I am not saying that this is the problem.
The first thing I notice is that your PSU is 700W the GPU alone needs 700W .

Minimum PSU Recommendation 700 W from here Click on me
So you do not have anything left over to power everything else.

I also notice that the ram is over spec for the CPU.
Max Memory Speed 2x1R DDR5-5200 Click on me

I will tag @phillpower2 to give advice on the PSU.

Thanks for the reply. Based on my research the pu supports my ram if thats what you meant by over spec. Also the minimum psu wattage spec from the amd website is calculated with the r9 7950x which has 170w tdp compared to my r5 7600x that has 105w tdp. Before buying the psu I checked the parts on https://pcpartpicker.com/ with the fans and everything and it said that the power consumption is around 500w. It suggested the minimum psu wattage should be 650w.

High end GPUs require the support of a high end PSU and you will not get that from any Cooler Master that is not at least Gold efficiency rated and even then they are not the best.

Big mistake and for as to why is explained below;

It is the GPU manufacturer that is expected to honour any warranty should the card fail because it was underpowered, not a PSU calculator or some faceless person on the internet that says that it is ok to ignore any minimum PSU requirements specified by the GPU manufacturer.

GPU manufacturer are not legally obliged to and nor will they replace a product or pay a refund for damage caused by the end user because they ignored the minimum PSU requirements specified by the GPU manufacturer.

The stock AMD card requires a minimum of a 700W PSU from a proven brand but I am aware of at least one third party brand RX 7800XT that requires a minimum of 750W so the first thing that we need to know is the actual brand of the GPU so that we can advise you on an appropriate quality and spec PSU.

The RAM is not appropriate for your CPU, AMD state here up to 5200MHz/MT/s and if you have EXPO/XMP enabled the RAM will get auto OCd past what the CPU can handle and the PC will become unstable.

You should also make sure that the Windows Power Plan is set to Balanced and not High Performance or Ryzen Balanced.

Something to keep in mind for the future, a CPU must be compatible with a MB whereas the RAM has to be compatible with both the CPU and the MB, this because a MB can be compatible with faster CPUs than the one in your list of parts and MB manufacturers often state RAM speeds that far exceed that which any compatible CPU can handle, this is misleading at the least or dishonest at worst.

What is the brand and model name or number of the RAM and how many sticks of it do you have, 2 Xs 16GB or a single 32GB stick etc.

First of all, thank you very much for the reply and detailed information.
My gpu is https://www.sapphiretech.com/en/consumer/pure-radeon-rx-7800-xt-16g-gddr6
About the RAM. I've checked again and it seems that I've made a mistake. I have 1 stick of Kingston Furry 32GB 5200MHz DDR5 CL36. So at least I picked the correct RAM. XD This is only my first build, so I'm still learning stuff.

The spec and quality of PSU that your rig needs is the example here

Your single stick of RAM can only work in single channel at 2600MT/s and is therefore bottlenecking your CPU.

You are welcome btw :)

I'm really suprised that you sent a link from a store in my town, but I guess that you could see my country somewhere. I know that as I was building around 1200 euros PC that PSU should't be too expensive for me, but unfortunately it is atm. I guess I can go a couple of months like this and than upgrade the PSU? About the RAM, if I went for 2x16 GB, whould that be better?

The first and foremost consideration is to look after your rather expensive GPU, until you have the required funds to purchase an appropriate PSU I strongly suggest that you remove the add on video card, store it somewhere safe and use the video from the CPU until you do have a PSU that can support the add on GPU, a weak PSU will slowly but surely damage the GPU.

The RAM would have been better as two 16GB sticks as you would have dual channel, my suggestion there would be to do whatever works out the least expensive for you, two new 16GB sticks and sell the present 32GB stick or add an identical 32GB stick.
