Dell Inspiron Desktop 3470 Repair — your questions answered

How much does it cost to repair a Dell Inspiron 3470 that won't turn on?

Power issues are usually the PSU or motherboard capacitors. Our fixed-price diagnostic starts at $89 and most power-supply swaps finish from $145 with parts and labour included. If the board needs capacitor work expect $220-$310.

Can you upgrade my Dell Inspiron 3470 to Windows 11?

Yes. The 8th-gen Intel CPUs in this model meet the TPM 2.0 requirement once the latest Dell BIOS is installed. We fit a supported SSD, add RAM if needed and perform a clean Windows 11 install for $180-$265.

Will replacing the hard drive keep my photos and documents?

We clone the old drive to a new SSD using sector-by-sector imaging so all data is preserved. The original drive stays with you or is securely wiped on site; recovery success is typically above 95 % when the drive still spins.

How long does a typical Dell Inspiron 3470 repair take?

Most common jobs such as PSU swaps, RAM upgrades or SSD migrations are completed the same day during an onsite visit. Motherboard-level capacitor repairs are done in our workshop and usually take two to three business days.

Do you still service these older Dell desktops in 2025?

Yes. Parts remain available and the platform is straightforward to repair. We carry compatible PSUs, DDR4 modules and M.2/SATA SSDs in stock for the 3470 series.
