Dell OptiPlex 5090 Repair — your questions answered
How much does it cost to repair a Dell OptiPlex 5090 that won’t turn on?
A no-power fault is usually the power supply. We test the 260 W or 360 W unit first; replacement starts from $145 and carries a 90-day warranty. If the motherboard has failed we quote after diagnostics and only proceed if you approve.
Can you recover data from a clicking hard drive in my OptiPlex 5090?
Yes. We clone the drive in our clean-room environment before any repair work. Most mechanical failures are recoverable if we act before further sector damage occurs; pricing ranges $180-$320 depending on how many bad sectors we encounter.
Is it worth upgrading an OptiPlex 5090 to Windows 11?
The 10th-gen Intel CPUs in the 5090 officially support Windows 11. A clean install plus an SSD and RAM upgrade usually costs under $300 and gives the machine another three to five years of reliable service for most office workloads.
How long does a typical OptiPlex 5090 repair take?
Most common jobs such as PSU or SSD replacement are completed same or next business day. Motherboard-level work or extensive data recovery can take two to four business days once parts arrive.
Do you offer onsite repair for OptiPlex 5090 towers in regional areas?
Yes. Our technicians travel to metro and many regional locations for a call-out fee that is credited against the final invoice. Remote diagnostics are also available if the machine can still boot to Windows.
