Your GPU died. The manufacturer won't help. Local shops can't do board-level work.
We can. And here's what we promise.
Your hardware, our Reliable approach.
While our primary focus is GPU repair, we also take on board-level work on other devices by request. Get in touch to discuss your device.
1. Repair pricing is fixed and quoted upfront. Additional charges may apply for expensive replacement components such as memory chips. This is always discussed and agreed with you before any work begins.
2. Free return shipping included on all successful repairs, sent by Royal Mail Tracked 48. You can upgrade the return service at the payment stage by paying the difference. See Policies & Terms for the full shipping policy.
