I sent Blackstone Repair my ASUS RTX 4090 after it developed intermittent black screens and eventually stopped being detected altogether. It also had an angled power adapter completely stuck in the 12VHPWR socket.

…Their online booking and repair portal was particularly good, with clear status updates, direct messaging, photographs of the work and progress updates as the repair moved through each stage. It made the whole process very transparent and easy to follow.

The failed adapter and damaged power connector were removed, the connector replaced, and the card was fully serviced and thoroughly tested afterwards. I was also provided with detailed test results and photographs, which gave me a lot of confidence that the card had been properly repaired rather than simply checked to see if it powered on.

The turnaround time was fantastic, especially compared with some of the other repair estimates I received, and the cost was very reasonable for the amount of work involved.

My RTX 5090 suffered a serious failure involving fire damage. Given the value of the card, I initially sent it to a specialist repair company in the UK. They dismantled and assessed it but ultimately told me that it could not be repaired.

Rather than simply attempting a conventional board repair, they carried out an extremely complex transplant using a donor card. The GPU has now been successfully brought back to life and is being correctly recognised as an RTX 5090, with the full 32GB of GDDR7 memory, 512-bit memory interface, PCIe 5.0 x16 connection and the correct shader configuration all showing properly.

What impressed me most was their willingness to take on a genuinely difficult repair rather than simply saying it was uneconomical or impossible. The level of technical skill required to diagnose the failure, source or use a suitable donor board and successfully carry out this type of transplant is far beyond normal electronics repair.

Absolutely mind blowing experience, I am lost for words how amazing this service for fixing cpu pins was, so my back story is a friend of mine 2 years ago gave me 3 x faulty bent pins AMD Zen 3 cpus, the 5800X3D, 5700X and 5900X, the multiple pins were really bent on each CPU and I tried my best to straighten but could not fix them…

…I have now put the 5800X3D in a build and it works perfectly fine, this business has real expertise in what they do and within less than a week of me talking to them sending cpus they fixed them the same morning they received it and posted them back to me. I cannot emphasise enough how good they are.
