HP Pavilion Gaming Desktop 790 Repair — your questions answered
How much does it cost to repair an HP Pavilion Gaming Desktop 790 that won't turn on?
Most no-power faults on the 790 are caused by the 500 W or 600 W PSU failing. Replacement with a tested OEM-spec unit usually costs $180-$260 including labour and carries our 90-day warranty. We test the motherboard first to rule out a short before quoting.
Can you recover data from a clicking hard drive in my HP Pavilion Gaming Desktop 790?
Yes. We image the drive in our clean-room hardware imager before any repairs. Typical cost for a full clone plus new 1 TB SSD install is $220-$320. We only proceed once you approve the quote and never work on a drive that shows imminent failure signs.
Is it worth upgrading the RAM and adding an SSD to an HP Pavilion Gaming Desktop 790?
Most 790 units shipped with 8 GB DDR4 and a mechanical HDD. Fitting 16 GB RAM and a 500 GB or 1 TB NVMe SSD usually costs $200-$280 and noticeably improves boot times and multitasking. The platform still supports Windows 11 after the upgrade.
Why does my HP Pavilion Gaming Desktop 790 keep overheating during games?
Dust buildup on the dual 120 mm fans and dried thermal paste are the usual causes. A professional clean, fan service and fresh paste costs $140-$190 and restores normal temperatures. We also check the GPU heatsink contact while the case is open.
Do you still repair HP Pavilion Gaming Desktop 790 units that are out of warranty?
We repair every 790 regardless of age or warranty status. Parts used are genuine HP or quality refurbished OEM equivalents. All work carries a 90-day warranty on parts and labour, and we offer onsite, remote or workshop options across Australia.
