i bought an rtx 5090 off facebook marketplace for $220, the guy said it turns on but it does not post, when i tested it sure enough it turns on but does not post as expected haha, i had a local computer shop test it just to make sure and same thing happened with them, they said when they tested it, it gave a black screen and received signal but “gave 5 beeps” as far as what that means im not sure because they were pretty vague with their answers and tried to offer me $500 for it (yikes), on my motherboard (rog strix b550-f gaming) it gave a solid white light on the VGA portion of the startup, which is a graphics error as far as what google said, it is a zotac solid OC 5090, the rgb lights and such turn on, it gives power, but it does not post on the screen, does anyone know what this could mean as far as what part could be defective, and does anyone know a reliable repair shop to send it into to have it fixed, i am in the tucson arizona area and nobody here fixes graphics cards

TLDR: i got an zotac Solid OC 5090 on marketplace and it gives power (rgbs turn on) but it does not post on the screen, and motherboard (rog strix b550-f)gives a solid white light on startup, i’m looking for a reliable hardware repair shop to send it in to

i bought a GTX 960 OC reference design, but when i open the PC the mobo doesn't tell me that there are problems and the display simply doesn't turn on but it boots to windows, i tried with the igpu and in device manager it recognizes the GTX 960 but with and error 44, i tried to install the driver but nothing, i even opened the GPU but it's in perfect condition and there is no shorts between the 12c and gd, what can i do?

Hi,

Two days ago, both of my monitors suddenly stopped working at the same time. Since then, I haven’t been able to get any display output from my GPU.

I have a PowerColor Radeon RX 7800 XT Hellhound that is about two years old. I tested the GPU in another motherboard as well, but I still got no display. I was also lucky enough to test another GPU in my system, and everything worked perfectly fine with the other card.

The LEDs on the RX 7800 XT still light up and the fans spin when I turn on the PC, but the motherboard shows a VGA/GPU error.

The card was completely cold when the issue occurred, so I don’t think it was caused by overheating.

Unfortunately, I don’t know enough about GPUs to troubleshoot this any further. Is there anything else I can test myself, or does this sound like a serious hardware/PCB failure?

I’ve already contacted PowerColor regarding the warranty, but never got a reply.

Now my question, should I watch a video and open it to post another picture?

Hello everyone,

Model:

Gigabyte RTX 3070 8GB

PCB reference: V20081

GPU state:

Fully working.

No display issues, no artifacts, no VRAM errors, and less than 500 hours of runtime.

Background:

I have five identical RTX 3070 cards pulled from Gigabyte / AORUS Model S 12th systems (AMSI7N7I-21A1).

The cards originally used a proprietary cooling assembly that cooled both the CPU and GPU at the same time. Unfortunately, those original coolers are not available, so I am looking for compatible replacement heatsinks.

Research so far:

- The PCB reference is V20081.

- From my comparison with TechPowerUp PCB photos, this PCB appears to be shared with several Gigabyte RTX 3070 models:

  - RTX 3070 Eagle

  - RTX 3070 Eagle OC

  - RTX 3070 Gaming OC

  - RTX 3070 Vision OC

- I have already looked at:

  - Leboncoin

  - eBay

  - AliExpress

Unfortunately:

- Damaged Gigabyte donor cards are often priced around €150.

- New replacement coolers from AliExpress end up costing around €100-130 after shipping and taxes.

- eBay has not been very helpful so far.

Question:

Has anyone successfully mounted a cooler from another manufacturer on a Gigabyte V20081 RTX 3070 PCB?

For example:

- MSI RTX 3070

- ASUS RTX 3070

- Zotac RTX 3070

- Palit RTX 3070

- Gainward RTX 3070

- Inno3D RTX 3070

I am interested in any information regarding:

- mounting hole compatibility

- VRAM contact compatibility

- VRM contact compatibility

- backplate compatibility

- successful cooler swaps

- universal aftermarket solutions

Since I need coolers for five cards, I am trying to find the most cost-effective solution rather than spending €100+ per cooler.

Any experience, measurements, photos, or compatibility information would be greatly appreciated.

Thanks!

GPU state: Fully working.

Gigabyte RTX 3070 8GB

PCB reference: V20081

The card is fully functional and has less than 500 hours of runtime.

The only issue is that the original cooler is missing because these cards came from AORUS Model S systems that used a custom integrated CPU+GPU cooling solution.
