If your Dell Precision 7820 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 2017. Parts are matched to the exact chassis, so the model number matters when we quote.

What we repair on the Dell Precision 7820
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 7820 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 7820 uses standard desktop memory. We check the board’s limits and fit matched modules.
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
Windows 11 support depends on the processor: versions with an 8th-generation Intel Core or Ryzen 2000-series chip or newer qualify, and earlier ones do not. We check yours and advise.
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 7820, along with no-picture and no-boot diagnosis, port repair, Wi-Fi and Bluetooth card replacement and data transfer to a new PC.
What we see on the bench
- 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 7820
Desktop drives are removed and imaged on our own equipment. If the Dell Precision 7820 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 7820 be upgraded?
Drives can be added or replaced. Memory uses standard slots and can be increased.
My Dell Precision 7820 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.
Where do I find the model number on my workstation?
The model is on a label on the back, side or underside of the machine. Dell machines also carry a 7-character Service Tag, which identifies the exact build. For this model, look for 7820.
Can the Dell Precision 7820 run Windows 11?
It depends on the processor. Versions with an 8th-generation Intel Core or Ryzen 2000-series chip or newer are supported.
