Hi everyone, my last build was plug & play, no issues at all. Not this time; nothing works.
My parts:
What else can I try? Any ideas which part is broken? Or did I do something wrong?
The KF does not have an internal GPU, and I did actually plug the cables into the GPU not the MoBo ;-)
Thanks for any help in advance
My parts:
Motherboard: | Gigabyte Z790 AORUS PRO X 1.0 |
BIOS Ver: | F4 |
GPU: | GeForce RTX™ 4070 Ti SUPER AERO OC 16G |
Cooler | DeepCool Assassin IV |
CPU: | i7-14700KF |
Operating System: | Windows 11 |
RAM: | Corsair 2*16 GB, CMH32GX5M2B6400C36W |
Power Supply: | Corsair RM850 |
Case: | Fractal North XL (don't think this matters, but to be complete) |
- I assembled everything, looks fine, turns on, then I get no display on the HDMI port. I flashed first the F5e Bios, after contact with Gigabyte back to F4. Still, upon startup the control led ist stuck at "VGA"
- Switched RAM slots (was and currently is in slot 2 and 4) -> no display
- put GPU into another PCIe slot -> no display
- I went to the store and bought a display port cable, and now I get something to see (my test-monitor is old and has no display port cable, so I tried with HDMI first)
- Installed Windows 11
- updated necessary drivers
- then noticed that the Gigabyte control center does not detect the GPU, neither does MSI afterburner or GeForce Experience
- I then saw that I can't change refresh rate, the display information just shows the resolution and "unknown". I also saw, that the GPU is only recognized as "Microsoft Basic Display Driver". I wanted to install the most recent gigabyte driver (552.22), but then computer crashes (no blue screen, just turns off). Automatically starts again, 3 times from bios restarting, then the blue Windows screen comes on and the only option I have is to reset the system -> updating Gigabyte driver not possible
- Gigabyte support said, the GPU is faulty, return it
- One last test: I was reluctant to dismantle my old but working computer, finally switched my old Asus GTX 1060 Ti 6 Gb to my new computer -> no display. Fans go on, RGB flashing in all rainbow-colors, no display, and after about 30 sec the fans go full speed. I have to shut down by holding the power button. I tried one monitor or two monitors with every possible combination of HDMI or DP.
- as now the old GPU was out of the was I put the 4070 into my old system -> wouldnt turn on (well, I did not expect this to work, but was worth a try).
- 4070 is on the way back to the distributor, not sure though the GPU is the (only) problem
What else can I try? Any ideas which part is broken? Or did I do something wrong?
