A GPU black screen or no display is usually caused by failed VRAM chips, a dead GPU core, or faulty display outputs. At GPU Doctor, we run full diagnostics including resistance measurements and voltage probing to identify the exact fault. Most black screen issues are repairable through BGA reballing, VRAM replacement, or display connector repair. Submit a repair request and we'll diagnose the problem as soon as possible.

GPU artifacts (random colored pixels, lines, or texture corruption) typically indicate VRAM failure or micro-fractures in the GPU die. We fix artifacts on NVIDIA RTX 5090, 5080, 5070 Ti, 5070, 4090, 4080, 4070 Ti, 4070, AMD RX 7900 XTX, RX 6800 XT, and all other models using VRAM reballing, chip replacement, and precision micro-soldering. Most artifact repairs have a high success rate.

Error code 43 means Windows detects your GPU but it's not functioning properly. Common causes include failed VRAM modules, damaged power delivery components, or GPU die issues. We specialize in fixing code 43 on NVIDIA GeForce RTX and GTX GPUs through component-level diagnosis and repair. This is one of our most common repairs with a high success rate.

GPU overheating is usually caused by dried thermal paste, degraded thermal pads, failed fans, or blocked heatsinks. We offer thermal paste replacement starting at $15, thermal pad replacement at $30, and complete thermal overhauls. We also replace failed fans. Temperatures typically drop 15-25°C after our thermal service.

We repair 60+ GPU models from NVIDIA, AMD, and Intel including: RTX 5090, RTX 5080, RTX 5070 Ti, RTX 5070, RTX 5060 Ti, RTX 5060, RTX 4090, RTX 4080 Super, RTX 4080, RTX 4070 Ti Super, RTX 4070 Ti, RTX 4070 Super, RTX 4070, RTX 4060 Ti, RTX 4060, RTX 3090 Ti, RTX 3090, RTX 3080 Ti, RTX 3080, RTX 3070 Ti, RTX 3070, RTX 3060 Ti, RTX 3060, RTX 2080 Ti, RTX 2080 Super, RTX 2080, RTX 2070 Super, RTX 2070, RTX 2060 Super, RTX 2060, RX 9070 XT, RX 7900 XTX, RX 7900 XT, RX 7800 XT, RX 7700 XT, RX 7600, RX 6950 XT, RX 6900 XT, RX 6800 XT, RX 6750XT, RX 6700 XT, and many more. We also service all AIB brands: ASUS, MSI, Gigabyte, EVGA, Zotac, Sapphire, XFX, PowerColor, and others.

Fans spinning with no display doesn't necessarily mean the GPU is dead. It often indicates a GPU core or VRAM failure while the power delivery is still working. We can diagnose the exact cause and in many cases repair the GPU rather than replace it. This is a common issue on RTX 3080, RTX 3090, and RX 6800 XT cards.

The diagnostic bench fee covers intake testing, power rail probing, and a written fault report. If you approve the repair quote we credit the fee toward the final invoice.

Standard repairs follow a 4-8 week bench timeline with regular updates. Need it sooner? Ask about our expedited lane for 7-day turnaround. We also offer a 2-day rush option for critical repairs. We prioritize quick turnaround while ensuring the highest quality repair work.

Yes! Melted 12VHPWR connectors are a known issue on RTX 4090 and RTX 4080 cards. We replace the damaged connector, inspect surrounding components for heat damage, and test power delivery to ensure safe operation. We also repair traditional 6-pin and 8-pin PCIe power connectors.

GPU crashes, game freezes, and blue screens (BSOD) can be caused by failing power delivery, overheating, unstable VRAM, or degrading GPU silicon. We diagnose the root cause through stress testing and component-level inspection, then repair the specific failing components. Common on heavily used mining GPUs and older cards.

Yes. For international devices, we will provide you with a shipping address, and when the device is fixed, we will ship it back to you with insurance. If you use your own carrier, upload the tracking number in the repair request notes so we can monitor delivery.

Every repair ships with a free 2-day workmanship warranty covering the serviced fault. You can extend coverage up to 30 days with our paid warranty options.
