Dell Precision T3620 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.
Overheating and fan repair
We clear dust from heatsinks, fans and filters, replace failed fans and renew thermal compound. On liquid-cooled systems we test the pump.
Windows repair and reinstall
This model does not meet Microsoft’s Windows 11 requirements, and Windows 10 reached end of support in October 2025. We can advise on the realistic options, including a lightweight Linux or ChromeOS Flex installation.
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 T3620 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 T3620 uses standard desktop memory. We check the board’s limits and fit matched modules.
We also carry out motherboard repair, virus removal on the Dell Precision T3620, 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
- Workstations often carry several drives, sometimes in RAID, and ECC memory. Tell us the configuration before any storage or memory work.
- Power supplies and motherboards are specific to the chassis on most workstation towers, so we match parts by exact model.
Data recovery from the Dell Precision T3620
Desktop drives are removed and imaged on our own equipment. If the Dell Precision T3620 has more than one drive, or a RAID array, bring the whole machine so we can see how it was set up.

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.
