What we repair on the HP Z4 G5
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.
Windows repair and reinstall
The HP Z4 G5 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.
SSD and storage upgrade
The HP Z4 G5 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 HP Z4 G5 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.
We also carry out motherboard repair, virus removal on the HP Z4 G5, 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 HP Z4 G5
Desktop drives are removed and imaged on our own equipment. If the HP Z4 G5 has more than one drive, or a RAID array, bring the whole machine so we can see how it was set up.

Questions

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.

Yes. It shipped with Windows 11.
