Windows repairs, reinstalls & upgrades · No Fix, No Fee · Same-day call-out
A computer that won’t boot, shows a blue screen of death (BSOD), freezes on the Windows logo or takes ages to start usually has a software or operating system problem rather than a broken part. PC Masters provides professional Windows repair, system restore and operating system installation for laptops and desktop PCs, at your home or business.
Your technician diagnoses startup errors, corrupted system files, failed Windows updates, driver conflicts and boot loops, then repairs the existing installation wherever possible so your files, settings and programs stay exactly as they are. Common fixes include startup repair, rebuilding the boot record, running system file checks, rolling back faulty updates and removing conflicting drivers.
When a clean Windows reinstall is the better option, we back up your documents, photos and emails first, install a fresh copy of Windows 10 or Windows 11, add the latest drivers and security updates, reinstall your software and restore your data. We also set up new laptops and PCs, upgrade eligible computers to Windows 11 and move Windows to a faster SSD for quicker startup and better performance.

Book online in a couple of minutes or call 0800 145 5521. Tell us what’s wrong and pick a time, Monday to Saturday, 9am–8pm.
A technician visits your home or business, finds the cause and tells you what it will cost before any work starts.
Most system repairs and reinstalls are done during the visit. If the job needs longer, we’ll take the computer to our workshop and return it fully set up.
If we can’t fix it, you don’t pay for the repair. We back up your files before any reinstall, and your data stays private. Every repair comes with a warranty from 1 month up to 36 months: our basic service includes 1 month, and the bigger the job, the longer the warranty.
Most Windows reinstalls use your existing licence, so there’s nothing extra to buy. If a new SSD would speed your computer up, we’ll recommend one and agree the price first.
Not if we can help it. We repair the existing system first where possible, and if a clean reinstall is needed we back up your files and put them back afterwards.
We check your processor, TPM and Secure Boot settings and tell you straight away. If it can’t, we’ll keep Windows 10 secure or suggest the most cost-effective option.
Usually not. Most computers have a digital licence that activates automatically after a reinstall.
Usually a few hours, including backing up, reinstalling, updates and putting your files and programs back.
