[SOLVED] Could I have physically damage my graphic card

[Leftnut99]

Hi, recently bought a rtx 3090 and install with the computer no problem. But when I started disassembling the gpu to instal new waterblock and backplate the pc stop displaying. I diagnosis every component of my computer and it only seems like the 3090 wont display. Fans and lights are working and the gpu heat up. I fear when handling the gpu I have somehow touch something bad. I have void the warranty by opening the gpu, so I need a hero right now. :_(

1. how did you get a 3090...
2. can you take a photo of the gpu

I would take it apart again and reassemble with the water block and back plate. If it still does not work then try putting the original cooler back on.

Is it possible there is permanent damage? Yes
However let’s hope it’s just something is not seated correctly and remounting fixes it.

Can you share a link to the exact gpu you have and the exact water block.

Common mistake is over-tightening the four main screws around the GPU, try and ease those a little and see if that does the trick.

Please tell us you weren't doing this with the power on...

Does it display anything upon power-on? Is the monitor active after power-on? WHat monitor interface do you use? What are the full system specs? Provide more info...

1. It was bought in China about 2 months ago, one of my friend was able to return to Hong Kong and get a hand of the last 3090.

2. I can take a picture but is just gonna be picture of the pcb. Also how do you post picture in this, sorry this is my first time using this website.

The display is black upon powering on? Yes the monitor is active power on as I have tested with other parts. I use display port.
The full system specs:

Ryzen 7 3800x
Asus B450f
Samsung 970 evo 1 nvme
Rtx 3090 innod3d
Corsair rx850
Corsair vengeance pro 3600 rgb
Aoc g2 series gaming monitor

like I have mention before, parts where posting with the 3090, I even installed window on the computer. After taking the gpu and installing the waterblock, there was no display. I swapped it out with my old rtx 2060 and it work fine.

???? The gpu was taken out before installing the backplate and waterblock.

I have try to run the gpu without anything just for the post, but I waited for no more than 30 seconds and screen is still black. This was done multiple time after the card cool down.

OK, I was just going by your text.

I have taken everything apart and reinstall into the pc. Still black. I even tried to with my old 2060, and it works. I have tried to remount the old heat sink with just a few screws on, fans seems to be running and lights are on, but still no display. The exact gpu I have is a innod3d 3090

I am not sure you got what I asked. Monitor becomes "active" when there is a signal from the port. Even if there is nothing to display. For example, on one of my monitors, the little LED in the corner changes color from yellow to blue when it becomes active.
AI: In addition, try booting with this card as secondary and see if it is being detected by the OS.

With regards to the whole story, I suspect either physical damage to the die or ESD shock. It is more common than you would think, just a few days ago someone likely did it while repasting and posted here. There is no protective lid on the die and it is very delicate. And so the ESD that you would not even feel will instantly fry ICs.
AI: Inspect the die edges and corners, that is where the dents and cracks are usually found.

Another common problem is physically bending the PCB while getting the heatsink installed and/or knocking small components off of it. One tiny 1x3 mm component missing may disable the whole board.
AI: Carefully examine the PCB for missing stuff.

There is one more thing I would try, connect the original heatsink and coolers back (there might be some sort of protection against a bad fan) and check your PCI-E AUX power cabling, but that would be about it. Further on you would want to take it to someone with tools and skills to use them.

Yes the monitor is active when plug into display port, it changes from orange to white , and back to white to orange. Thankyou I will check those tonight. I’m not sure what die and esd is, but gpu fans and light are working when they are plugged back in. And gpu heats up.

That water block says it is for 2 specific EVGA cards and you are using a inno3D card. Unless that water block says somewhere it is compatible with the inno3D card it should never have been used. You must use a water block specifically designed for the exact model of gpu.

hi sorry, i only picked the most similar looking waterblock on the internet to mine. The waterblock itself was hand picked by the professionals at Bykski, after inspecting the PCB on the gpu and the back. Sorry for the confusion.

Ah phew, that’s ok then

 

[Leftnut99]

here’s an update:

I plugged my old rtx 2060 into pci-e 1 and my new rtx 3090 to pci-e 2, i plug my display port into the rtx 2060 and greeted into the bios. The bios indicate that there in fact two gpu at the spot I install it to. Yet the screen is black when I plug it into the rtx 3090

That is a good sign, the chip might be still OK.
When it is recognized as secondary (2060 primary) get into the operating system and install drivers for both cards, see if it lets you doing it. After that will make a few tests to try to see what is damaged. Try switching interfaces (display ports).

• ESD stands for electro-static discharge
• “die” is the the actual chip, the surface where you attach the heatsink. More.

Phew. Yea i was going to do that. I believe when I instal first gen windows 10 it may have automatically install an old, buggy driver into my rtx 3090. Also I heard I should download UDD to uninstall my gpu driver, if updating the driver doesn’t work. I hope that is the final resolution.
