Desktop PC Repair FAQs

How much does desktop PC repair cost?
Every repair starts with free diagnostics and an upfront, no-obligation quote — so you always know the price before we begin. Costs depend on the fault and your PC; common jobs like SSD upgrades or power supply replacements are affordable and often done the same day.
How long will my repair take?
Most desktop repairs are completed the same day. More complex jobs such as motherboard or graphics card repair may take a little longer — we’ll always give you a clear timeframe with your quote.
Can you make my slow PC faster?
Yes. An SSD upgrade, extra RAM, a clean Windows reinstall and a full tune-up can make an old desktop feel brand new. We’ll recommend the best-value upgrades for your machine before any work begins.
Do you repair gaming PCs and servers?
Absolutely. We repair every type of desktop — high-end gaming rigs, office servers, workstations and all-in-ones — including graphics cards, cooling, power and overheating issues. If you’d like a brand new machine built, see our Custom PC Builds service.
Which PC brands do you repair?
All major brands including Dell, HP, Lenovo, Acer, Asus and MSI, plus custom-built and gaming PCs with Intel, AMD and NVIDIA parts. For Apple iMacs, see our dedicated Mac Repair service.
What if you can’t fix it?
Then you don’t pay for the repair — that’s our no fix, no fee promise. You only pay when your PC is working again.
