Do you have any suggestions on how to try to fix the situation with your GPU not showing a display?
I recently left my ITX PC for a while, and when I returned it didn’t display anything on the monitor. The GPU lights would activate and the fans would spin, but nothing appeared. I thought the connection might have loosened, so I adjusted it a bit and it worked again. However, once I started playing games, the display would randomly disappear (especially during TLOU2, about every 20-30 minutes). It would force a restart, then the screen would appear again until it cut out again when under load—usually while browsing or opening apps. Browsing was fine, but it would cut out when launching games or random apps.
The problem got worse over time, sometimes not showing any display at all when turning on the PC. Eventually, after a bit of adjustment, it worked again, but then it stopped working entirely and wouldn’t reach the BIOS. The monitor would show 'no signal' and the motherboard would flash a constant white VGA error light.
I had a spare PC with a different GPU that was functioning perfectly. It matched the behavior, so I suspected the issue might be with the PCI-E connection. I tried changing it to PCI-E 3.0 in the BIOS, but that didn’t help. I removed everything from the case and connected my current GPU directly to the motherboard, but still no signal—only the VGA error light stayed on. I also tested my old GPU in the spare system, which worked fine. My current GPU in the old system did not show any signal either.
It seems my current GPU might be damaged, possibly due to the riser cable or the PCI-E connector. It could also be related to the connection itself. Any suggestions on what I could try next?

When sharing a troubleshooting thread, it's standard to provide your complete system details. Please share the specifications of your build in this order:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
Please include the age of the PSU along with its make and model. BIOS version for your motherboard at this time.
If the GPU was connected via a rigid riser cable or slot, you may want to check the PCIe slot for any damage or misalignment.

Without the full specs, it would be guesswork. I recommend considering a VBIOS reflash, but first examine the entire PCB for any cracks or breaks.
I'm not too sure if detailing the rest of my specs will help much, since everything is currently functioning well with my old GPU. This seems to point mainly to an issue with my current GPU rather than anything else. The problem doesn't show up on my spare build either, which also works fine with my old GPU. Here are the details I have.
GPU: Previous GPU - 3070 EVGA XC3 / Present (damaged) GPU - 3080ti Asus Tuf

As I mentioned, my previous GPU functions adequately, which makes it unlikely the slot is the problem. Nothing has changed physically since it was working intermittently a few days ago.
The power consumption for both cards differs. You might consider obtaining a more powerful, well-built PSU and checking if the issue continues. To note, the PSU in the affected system is two years old?

Maybe check if your BIOS needs an update and reset the CMOS. A partially faulty BIOS could be responsible.

Solving this involves narrowing down possibilities rather than making assumptions.
I thought this was already covered, but I believe the problem is something that can be fixed. It wasn’t a display issue before a few days ago, but after some shaking and pressing, it seems the card still functions and isn’t completely beyond repair. RMA isn’t an option—it’s well past warranty, it’s not a brand-new GPU, just my current one.
I don't have an 'afflicted system'. I have two distinct systems that all function perfectly with my old GPU, but not with the current one. Both power supplies are about two years old, possibly even less.
How did you obtain this new GPU?
If it was sold in perfect condition, the seller might have detected something amiss.
Inspect it thoroughly, focusing on the power connections.
The original GPU model lists a power consumption of 650 watts.
The updated specifications indicate an 850-watt rating, which is significantly higher.
Each GPU needs two 8-pin connectors.
When you plug in the cables, are you using one long cable with multiple ends?
Or are you connecting two separate cables and only using one 8-pin connector from each?
The latter method is preferred.
A single cable might not be sufficient to handle all the necessary current.
It hasn't been 'new' at all, I've been using it regularly for several years in the same rig and PSU. The problems only appeared after I took it abroad, likely due to rough handling in my luggage. Despite that, it still functioned properly—I played on it for many hours after returning before issues arose. It has two 8-pin connections.
To be sure, is the link made with just one 8-pin connector from each side? Or are you employing a single cable featuring two 8-pin connectors for better organization?
It seems the power supply unit might be the problem.
Would you like to test it with another reliable PSU of at least 850 watts, ideally higher?
