PC lights up, no display, front fan LEDs turn off

Hello! I've just gotten a new motherboard and CPU, and after installing everything it doesn't come up with a display. The front fan LEDs also shut off but the fans still run. I've removed the GPU and plugged directly into the motherboard and same issue. I've also checked all of the connections and haven't found any issues. I'm using a Corsair hub with all Corsair fans for the led and fan controls. The power supply is also new as of a few months ago. motherboard is strix b650-a gaming wifi CPU is amd Ryzen 7 7800x3d any advice is much appreciated!

Clearly his hardware is the problem

Found some nostalgia on an old drive (201.

Is this price ok for its Performance

First Gaming pc what do you think, Should i change something? Max 1200€

GPU upgrade isn't enough (CPU Bottleneck )

Looks like the old Ryzen 5600 can't keep up with the young 3080ti I bought. 😔

I read that Fractal Torrents have some pretty horrible QC on their front fans, it appears its happened to me aswell

Why do I have this installed when I have a Ryzen CPU?

It is currently so hot here in the UK I’m having to run my GPU fans when idle to prevent 20+ degrees C spike

My GPU is taking such a heavy hit from the heat wave at the minute but weirdly I have not had to increase the curve of my AIO

Xmp issue

Don't know if this is the right place to post this but I'm having trouble confirming if my xmp is enabled or not. As per the provided picture, I enabled xmp, but my ram speeds stay the same. Task manager and CMD also show 2133mHz. Bios is up to date. SAM enabled (don't know if it's related to the problem). Feel free to ask for additional information.

Cooling advice fan configuration

Current set up: I need help with some cooling/fan advice. The current set up/fan configuration shown in the picture(red arrows). I’m using a CIT flash micro ATX case(not the best at airflow), I’ve modded the case to remove the glass front panel and changed it to a mesh panel for better air intake. The fans are your standard ones that come with case. You cannot control the speed, just runs on full speed all the time. Running most games the CPU temp is between 65-78 degrees. I want to try and bring that down if possible with better fans/configuration. Question: should I replace the existing fans with decent airflow fans? Should I add another fan as an exhaust at the top (green arrow)? I don’t really wanna go down the AIO route if I don’t need to.

What's wrong with this ?

Hey guys , I need help with this. My laptop don't charge anymore even after changing the battery. I checked this plug , make the pins closer and it worked, I remounted the PC and it didn't work anymore. Retried the operation, nothing...
