Brand new PC refusing to function properly

[GTechGeorge]

My best friend & I made a Micro Center trip a few weekends ago to get his parts for a new PC as you do, but ever since building it he has not been able to keep the thing stable resulting in frequent crashes, BSOD's, freezes, loss of display, etc. The current culprit seems to be something GPU, or at least GPU driver related, as the PC will not keep the most recent NVIDIA driver installed. Upon restart the driver seemingly uninstalls itself and the GPU is no longer detected by the system, albeit the video cable is still plugged into the GPU and not the motherboard. I still need to double check to ensure the PCIe connector is running the GPU riser at PCIe 4.0 speeds as well.

 

So far I have:

• Confirmed the RTX 4080 works on my test bench, installs drivers fine and passes stress tests
• Confirmed his system runs stress tests just fine with other GPUs; I used DDU first and tried a GT 730 & GTX 1660 Ti respectively, both worked fine
• Loaded optimized default BIOS settings to run at default RAM speeds and ensured the most recent BIOS update is installed
• Reinstalled all motherboard drivers on his PC
• Updated Windows to the most recent version

 

He has fresh reinstalled Windows from scratch at least two or three times now.

I'm tempted to tear apart the whole system, completely wipe the SSDs entirely and rebuild it myself to see if some weird, obscure problem is causing this but I'd love to hear additional input/troubleshooting steps.

 

All components were purchased brand-new from Micro Center maybe 2 weeks ago tops.

• AMD Ryzen 7 7800X3D
• Deepcool LT520 AiO
• G.Skill 2x32GB DDR5-6000
• Gigabyte B650i AORUS ULTRA
• Samsung 980 PRO 1TB M.2
• Crucial P3 Plus 4TB M.2
• ASUS RTX 4080 ProArt
• Cooler Master V1100 SFX Platinum PSU
• Lian Li Q58 (White)
• Windows 11 64-bit

 

The CPU also shows up in HWinfo like this for some reason?? RTX 4080 didn't display here at all, although it showed up in Task Manager after installing the driver but disappeared after restart.

Does seem like a gpu issue indeed. I'd take it out of the case and run it without the riser to see if the issue persists. Is the 12vhpr connector 100% fully inserted on both sides?

 

Best would be if you have another system to test the gpu in.

 

HWinfo seems to be an older version, can be buggy with newer hardware.

Your HWInfo is buggy af, what's an Intel Pentium AMD Ryzen 7800X3D ?

Whatever, for the GPU shennanigans did you try to plug it without a riser cable ? Sometimes they can be defective

As mentioned yes, I removed the RTX 4080 from the PC and installed it into my test bench without the riser cable. I did also use the included 12VHPWR adapter with three distinct 8-pin PCIe cables opposed to a dedicated 12VHPWR cable such as the one included on my friend's power supply.

Yes, I ensured the 12VHPWR connector was 100% inserted properly, both on the GPU and the PSU ends.

Ah didn't read that right first time, if the gpu works fine on another pc I would expect the gpu to be ok. I'd suspect the riser, try running it outside the case without it and see what it does.
