How to choose a service center for repairing a graphics card with suspected memory failure?
My graphics card likely has faulty memory, as monitors go dark at random moments: sometimes during gaming (Unreal Engine DX12), and also during long video rendering in Adobe Premiere (after 30-40 minutes). The only solution is to restart the system.
I have already performed basic diagnostics: checked all connections, cleaned it from dust, and checked the cables. My technical knowledge ends here, so I need help from a service center.
Please advise, should I go to the DNS service center? How long might they keep my computer for repair? Is it possible to restore a graphics card with faulty memory? (I’m confident the problem is specifically with the memory, not overheating).
Repairing a video card with memory failure requires choosing a specialized service center with appropriate equipment and experience. DNS may consider your application, but it’s worth considering alternative services that specialize specifically in complex video card repairs, including memory chip replacement and rework. The recovery process typically takes from several days to two weeks, depending on the complexity of the failure and parts availability.

How to choose the right service center
When selecting a service center for repairing a video card suspected of memory failure, several key factors should be considered:
Specialization in video cards
Look for services that specialize specifically in video card repair, rather than offering general computer equipment servicing. Such centers typically have:
- Professional equipment for diagnosis and repair
- Experienced engineers familiar with different manufacturers’ architectures
- Access to specific parts and memory chips
Important: Ensure the service has experience working with video card memory, as this is one of the most complex components to repair.
Equipment and technology
Quality video card memory repair requires special equipment:
- Infrared rework station for chip reballing
- Programmers for testing and replacing memory chips
- Memory testers for fault diagnosis
- Clean rooms for working with sensitive electronics
Warranties and reviews
Be sure to check:
- Terms and duration of warranty on work performed
- Customer reviews, especially regarding memory repairs
- Pricing transparency
- Diagnosis and repair timeframes
Research shows that Moscow has several services specializing in video card repair: Vik-on service, Tekh-Profi, Repair Laboratory, Notebook Doctor.
Analysis of DNS service center
DNS is a large electronics store network with its own service centers, but there are several important aspects to consider:
DNS advantages
- Extensive network of service centers across Russia
- Official partnerships with manufacturers
- Standardized service processes
- Possibility of warranty repair for goods purchased at DNS
Disadvantages and risks
According to user reviews from research:
- Frequent warranty repair refusals due to “signs of use” and dust
- Extended repair times (up to 45 days according to official policy)
- Insufficient customer communication
- Problems with diagnosing complex failures
Critical point: One user noted that DNS refused warranty repair for a GTX 950 video card, citing a detached serial number, despite having a receipt and active warranty.

Video card repair timeframes
Timeframes depend on several factors:
Diagnosis
- Usually takes 1-3 business days
- In complex cases, additional time may be required
- Some services offer express diagnosis for 15-30 minutes
Memory repair

Warranty repair at DNS
According to official DNS information:
- Warranty service period does not exceed 45 days
- Warranty is extended for the period the product is in repair
Possibility of memory recovery
Recovering a video card with faulty memory is technically possible, but the difficulty depends on the nature of the failure:
Typical memory failures
- Individual chip failures - most common problem, solvable by replacement
- Contact issues - can be restored by reballing
- Memory controller damage - usually an unsolvable problem
- Physical damage - can be repaired if parts are available
Repair methods
- Memory chip replacement - requires BGA component soldering
- Reballing - resoldering chips to restore contacts
- Testing and programming - in some cases, chips can be “revived”
Success factors
- Quality of service equipment
- Engineer experience
- Parts availability
- Nature of the failure
As shown in video repair tutorials, professional video card memory repair is a complex process requiring special training.
What to expect during repair
Repair stages
- Diagnosis - confirmation of memory failure
- Video card disassembly - careful chip extraction
- Board cleaning - removal of old solder
- Installation of new chips - using an infrared rework station

- Assembly and final check
Repair cost
Prices vary depending on complexity:
- Diagnosis: free or 500-1500 rubles
- Replacing one chip: 3000-8000 rubles
