parts list: motherboard mag B650 tomahawk, graphics card AMD radeon RX 7900 XTX sapphire nitro +24 GB, CPU ryzen 9 7900x, ram corsair, vengeance, DDR5 2 sticks 16 GB at 6000 MHZ, power supply corsair RM 1200 X

so far, I’ve tried putting only one stick of RAM in slot too while booting had no effect. I’ve looked all over the Internet and have yet to find anything useful I’m willing to try anything. I’ve had this PC for a month now and have not been able to get it to start although I haven’t tried a lot of stuff due to being busy with work.

What have you tried prior to creating this thread? You should still be able to get display out from your system if you hook up your monitor to the motherboard(since your processor has an iGPU) and you've removed the discrete GPU from the system.

Got a link to the ram you're working with? Rams populating slots A2 and B2 on the motherboard?

How are you cooling the processor?

hey so i tried taking my gpu out and it booted up idk if that means i need a new gpu but i had work at one point its also brand new if you have any suggestions please let me know
 
Just a suggestion, connect the HDMI cable to your iGPU port and start the PC. Go into the BIOS and select iGPU for video save and boot the PC. Hopefully you should have video at this point, download and install the driver from AMD Driver site for your RTX graphic card. Shut down the PC. Reinstall your graphic card and plug in the HDMI cable to your card.. Start the PC go into the BIOS again and select the PCIEx port for your graphic card and save settings and reboot the PC. Hopefully if all goes well you will have video with your RTX card. As long as you have selected the PCIEx port your graphic card is plugged into for video output in the BIOS it should work. This method has worked for me with various PC's in the past.

I had this same issue recently. Have you tried to flash the bios? This worked for me for a while until it didn't.

Came down to having to RMA the GPU to replace the 12VHPWR (12 Pin connector on the GPU). Not sure if your GPU uses this connection type or not.
