What we repair on the Dell Precision 3440
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.
Memory upgrade
The Dell Precision 3440 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 3440 meets Microsoft's Windows 11 requirements in most configurations. We upgrade from Windows 10, which reached end of support in October 2025, or reinstall Windows 11 cleanly with your files kept.
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.
SSD and storage upgrade
The Dell Precision 3440 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
We also carry out motherboard repair, virus removal on the Dell Precision 3440, 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 3440
Desktop drives are removed and imaged on our own equipment. If the Dell Precision 3440 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 3440 be upgraded?

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.
