PC starts up but there is no screen or connection to the keyboard.
I’ve been assembling PCs for eight years now, creating many for friends and family, yet I’m facing this issue.
I’m using an older Intel Desktop 01 board with a 5500 XT GPU installed—it performed well until it suddenly stopped. After rebooting, there was no signal detected. When I tried again, it functioned properly.
A week later, I’m unable to establish any connection at all. Even my previous GTX 970 and 480 work, but this 5500 XT doesn’t. I recently purchased it without any visible damage or smell (I’ve experienced card smoke before). It had been running below 75% capacity next to an open window.
I’ve tried several steps:
- Removed the CMOS battery
- Replaced the CMOS battery
- Swapped out the RAM
- Used a different power supply
- Tested with older GPUs, which worked
I don’t have another motherboard to test on, but it seems this GPU might be the culprit. It happened the same week before and then worked again mysteriously.
Additionally, the monitor displays input signals, so it’s receiving data.
Just tested it in another completely different PC—removed the 1050 Ti and used the 5500 XT, but nothing changed.
Any suggestions on what might have caused this?
Edit: I disassembled the GPU, received a refund, and examined it closely using a magnifying glass (used by an esthetician). No visible damage was found. The fans are spinning, and the TV appears to be receiving power from the GPU since input is shown. Also, when I powered it off, it restarted automatically.
Can you tell me a reason, why brand new hardware comes with a warranty?
Do you have hardware to detect microscopic cracks inside the GPU die itself or in other (control) chips the GPU has? If not, then there's your answer. Microscopic crack (manufacturing defect) was the culprit. As of what chip is the culprit, you have to test the whole board with multimeter. If you don't know how, send the GPU to Northridge Fix and let Alex to repair it for you, IF it can be fixed.

Else-ways, scrap it or use it as spare parts.
Btw, PSU make and model (or part number) is? Also, how old the PSU is, and was the PSU bought new or used/refurbished?
Among the three power supplies I tested, all were 500W and between 2 to 5 years old; one was just purchased last month. I don’t have any tools to identify tiny cracks. My worry was that this issue occurred before and it resolved itself again. Regarding Northridge, it appears to be targeted mainly at Americans, as I’m from Canada.
Nortridge does international shipping/repairs.
Alex has youtube channel that i've watched to learn more about electronics repairs. In his videos, he has stated that people as far from India or Australia have sent their electronics in for repairs. So, you still can use their service.
Well, out of the 5 cars i've had, all had 4 wheels and were 8-16 years old. But that doesn't tell which cars i've actually had.
So, i'll ask again;
🤔
Well, then you can do your "magic" again, if you think you can magically make the dead hardware operate again. Though, this makes me wonder regarding this:
How many component failures you've had?
🤔
I get a feeling that none, since your knowledge about hardware failure is common among those who have little to no clue, by trying the same thing over and over again, hoping that the GPU magically fixes itself and works like brand new GPU.
Since you've gutted the GPU, there is no warranty for it anymore. IF you want to get it fixed, contact Northridge Fix (or any electronics repair shop) and send the GPU in for repairs. If not, keep it as a paperweight.
And while you've inspected the GPU PCB with microscope, you can not detect short circuits. E.g this video from Alex is good example to show, where components on PCB look fine, but as soon as it is measured, board tells short circuit, since specific chip on the board is bad. After Alex replaces the chip, board works.

Any idea why there's still a display option? That's the only hope that the card is still salvageable because something is clearly going out to the monitor.
I haven't seen a PCIe pin in this condition before (possibly damaged). Checking two other GPUs didn't reveal anything similar.
GPU continues to transmit identification data to the system, yet because of the GPU malfunction (possibly a dying GPU or driver chip), it can't produce the display image. Generally, the most frequent issue is that the GPU fails to show anything at all. However, there are instances where using standard Windows display drivers allows the GPU to function correctly and render images. Once GPU-specific drivers are installed, the GPU stops displaying content. This suggests a driver chip failure. There may also be artifacts appearing in the image, which can help pinpoint the problem—such as BUS, VRAM, or GPU chip issues. If using a DVI cable, DVI corruption could also be responsible. You've already verified with other GPUs that the rest of your system and monitor operate normally. The 5500 XT model in another setup also shows no image output, indicating the fault lies with this particular unit. Not the highest resolution photo, but it appears the second pin on the right side is damaged near the tip (unimportant). What does the opposite side of the PCI-E connectors look like?
Speaking about PCI-E connections on the GPU, a recent video by Alex demonstrates how to repair such issues; you can watch it here: (At 00:58.)

The backside above shows the 5700 XT beside my 970. Are the two pins in the middle grey?
