Question The most impossible problem

[Htf333]

Lads,
I come in a time of great, great need.

I recently bought a prebuilt from Lenovo.
Legion Tower 7i Gen 8 / RTX 4070ti / i7-13700KF

Here is where the problems began.
On the 15th of September, the PC arrives. I was tired from work and school so I left the box as is.

The next day, I open it up. I see all the RGB, and the thick brick that is the RTX 4070ti, and my eyes light up like a kid at Christmas Eve. Oh, how I wish I could be as happy as I was then.

Upon boot up I noticed I couldn’t access Nvidia’s control panel. No problem, I thought. A quick driver update should do the trick.

After a quick few minutes, the install is complete. However, once I’m done, I see an odd message.

But how? I just installed it? No matter, I try it again. And again. And again. It still does not change anything. Nvidia control panel won’t open up no matter what I do. When I finally do manage to wrangle it open, I see this:

This is where I fall down the inescapable rabbit hole. I quickly discover my gpu is not being used by my pc. I have a KF cpu, so surely my pc is using the gpu somehow otherwise I wouldn’t see a screen.

Here’s a list of everything I tried. Please try to imagine the pain I went through.

———

Gpu shows in device manager
Not in task manager
Drivers install loops (after installs says I need to install again as if I didn’t just do so)
Installed manually and also via GeForce experience
Certain apps show GPU, (GPUZ) other apps do not (CPUZ)
Full uninstall of all drivers (DDU) and reinstall
Remove GPU, reseat GPU
GPU too big to put into other Pcie slot
Downgraded to windows 10
Upgrade to windows 11
Swap RAM sticks
Set PCIE to Pcie3 in BIOS
Boot logging shows drivers being loaded in, but “dxgkrnl.sys” is failing to load
Attempted sfc /scannow (fixed a corrupted Bluetooth driver issue but that is it)
chkdsk yields no results
Reinstalled directX12
Windows Memory Diagnostic Ram Test
Stress test software says gpu is not valid
removed cmos battery
Bios Reset
Using WUShowHide to pause certain updates after PC reset in case they caused issues

Now, before I did any of this of course I called Lenovo and told them to fix my PC. They said they can send a replacement within 15-20 days. But I won’t have a working PC for 20 days? How am I supposed to get any work done? I am also moving soon, within 15 days, to another country. So I will likely not be here to receive it.

I’m going to get a replacement no matter what. Hell, I will even try to get the replacement upgraded since they’ve greatly inconvenienced me by sending a defective unit, making it so I cannot do anything with it aside from browsing the web and using email. The whole point of buying a prebuilt is to face zero issues.

Is there anything anyone here can suggest to help me? I am out of options.

I sound desperate because I am. I was so excited for it only to get slapped in the face with this…

Welcome to the forums, newcomer!

I would suggest that you paid for a system that's working out of the box, I wouldn't troubleshoot the prebuilt. Then again, since I know what might be the issue, I'd try and recreate the bootable USB installer for the OS and then reinstall Windows 11 in offline mode, then manually install all drivers in an elevated command, i.e, Right click installer>Run as Administrator.

Thank you sir. I haven’t tried that yet, so I will when I wake up tomorrow will keep you posted. When you say reinstall windows in offline mode, do you mean disconnect my Ethernet cable and everything? Also, when you say recreate bootable USB installer you mean to suggest that I should basically fresh install windows 11 again off a usb?

Again, thank you for the help.

Hello. I tried your steps exactly. It didn’t end up working. I’m going to get the entire pc replaced. Thanks for the help

It sounds like you have the monitor cable attached to the motherboard port instead of the graphics card port.
