Servers
No-boot, reboot loops, crashes, error codes and performance faults across major rack and blade platforms.
SERVER & GPU REPAIR
Server Repair & GPU Repair
From system faults to GPU module-level repair for H100, H200, H800, H20, A100, A800, B200, B300 and GB300 - genuine parts, per-incident or annual plans.
- 20+ yrshardware experience
- 48hresponse & parts
- 3-7 daystypical turnaround
A day of GPU downtime can cost an entire training cycle. Daoshen repairs servers and NVIDIA GPUs at board and module level, covering no-boot faults, dropped cards, memory errors, power anomalies, thermal alarms and PCIe or NVLink link failures, plus RAID and data recovery.
The team brings 20+ years of enterprise hardware experience, with BGA rework stations, oscilloscopes and full-load GPU test benches. Repairs are validated over 24-72 hours before handover, with common spares in stock and 48-hour response for remote sites.
SCOPE
What we repair
Systems, components and data - all three layers.
GPU cards & modules
Dropped cards, artefacts, memory errors, fan and thermal faults, power and PCIe issues - module-level repair for H100 and H200.
Storage & RAID
Drive drops, degraded arrays, failed rebuilds, array metadata and data recovery.
Networking
Switch port faults, optics failures, stacking and link troubleshooting.
PSU & mainboard
Power modules, VRM rails, capacitor and BGA solder joint rework.
Workstations
Graphics workstations and thin clients, repair and part replacement.
GPU REPAIR
GPU repair capability (H100 / H200 / H800 / A100 / A800)
Module-level rework instead of a premature write-off.
Memory replacement
HBM / GDDR testing and replacement to clear memory errors and missing capacity.
Power & VRM repair
Power stages, MOSFETs, inductors and controller ICs repaired at component level.
PCB & BGA rework
Cold joints, missing parts and burnt traces, with X-ray inspection and rework.
Thermal service
Fan, vapour chamber and thermal paste replacement to restore clocks.
NVLink / PCIe faults
Link training failures, bandwidth anomalies, bridge and gold-finger repair.
Firmware & VBIOS
Reflash, rollback and verification of corrupted or mismatched firmware.
MODELS
GPU models we repair
From Hopper to Blackwell Ultra - module-level repair, not automatic write-off.

FAQ
Frequently asked questions
01Can you repair newer platforms such as B200 and GB300?
Yes. Memory, power and cooling modules on B200, B300 and GB300 are within scope, and core GPU failures are assessed for module or card replacement. Spares for new platforms arrive in batches, so send the unit in for diagnosis first.
02How much does H100 or H200 repair cost?
It depends on the fault. Memory and power rail repairs typically run 10-30% of the card price, while core or module replacement costs more. We always diagnose and quote before any work begins.
03What is the turnaround time?
Common faults such as dropped cards, memory errors and power issues take 3-7 business days. BGA rework or module replacement takes around 7-15 business days, with an expedited option for urgent projects.
04Do you use salvaged parts?
We use genuine or equivalent-specification parts, and every replacement is listed with its model and source in the repair report.
05Can you repair on site?
Engineers attend on site in major cities for diagnosis and part swaps; otherwise we arrange insured shipping for bench repair.
06What if the repair fails?
If an approved repair cannot be completed, the labour fee is waived (diagnostics excluded), and we can discuss trade-in, buyback or reuse as spares.
07How is an annual maintenance contract priced?
By device count, brand and model, response tier (4-hour, next-business-day or 48-hour) and spare coverage, including scheduled inspection and firmware updates.
