If your Dell Precision 3660 will not start, shows no picture, runs hot or has become slow, we can diagnose and repair it at our Bermondsey workshop. It is a workstation from 2022. Parts are matched to the exact chassis, so the model number matters when we quote.

Dell Precision 3660 repairs and upgrades
Power supply repair
We test and replace failed power supplies. Many branded desktops use a manufacturer-specific unit, which we match to the exact chassis.
SSD and storage upgrade
The Dell Precision 3660 has room for SATA drives and, on most boards, an M.2 SSD. The usual upgrade is an SSD for Windows and programs with the old drive kept for storage.
Price confirmed before work starts
Memory upgrade
The Dell Precision 3660 uses standard desktop memory. We check the board’s limits and fit matched modules.
Overheating and fan repair
Overheating and noise are usually dust or a failing fan. We clean the system, replace what has failed and check temperatures under load.
Windows repair and reinstall
The Dell Precision 3660 shipped with Windows 11. We repair start-up faults, reinstall Windows cleanly with your files kept, and remove malware.
Graphics repair
We diagnose and replace failed graphics cards, and check that the power supply and case can take the card you want before an upgrade.
We also carry out motherboard repair, virus removal on the Dell Precision 3660, along with no-picture and no-boot diagnosis, port repair, Wi-Fi and Bluetooth card replacement and data transfer to a new PC.
Known issues with the Precision tower workstation range
- Power supplies and motherboards are specific to the chassis on most workstation towers, so we match parts by exact model.
- Workstations often carry several drives, sometimes in RAID, and ECC memory. Tell us the configuration before any storage or memory work.
Data recovery from the Dell Precision 3660
Desktop drives are removed and imaged on our own equipment. If the Dell Precision 3660 has more than one drive, or a RAID array, bring the whole machine so we can see how it was set up.

Questions
Can the SSD or memory in the Dell Precision 3660 be upgraded?
Drives can be added or replaced. Memory uses standard slots and can be increased.
My Dell Precision 3660 will not turn on. Is my data lost?
Usually not. The drive is separate from the fault in most cases, and we can remove it and copy your files even if the machine itself is not worth repairing.
How do I get my Dell Precision 3660 to you?
Bring it to our workshop at Unit 1 The Willows, 80 Willow Walk, London SE1 5SY, or call 020 7237 6805 to ask about courier collection. We confirm the price before any work starts.
Can you upgrade the graphics card in a Dell Precision 3660?
In most cases, yes. We first check the power supply, the physical space and any manufacturer-specific connectors, then fit and test the card.
