PC Health Check Online: a faster, safer computer in about an hour
A UK engineer connects securely, runs our 34-point health check on your Windows PC or laptop, and fixes what’s slowing it down. Like a car service for your computer — no need to bring it anywhere.
Signs your computer needs a health check
Most slow PCs aren’t broken — they’re clogged. If any of these sound familiar, a tune-up usually brings it back to life.
Slow to start up
Minutes to reach the desktop, or a login screen that just spins.
Freezing & lagging
Programs hang, the mouse stutters, and tabs take an age to load.
Disk almost full
Windows nags about space and updates fail to install.
Pop-ups & odd behaviour
Unwanted toolbars, redirects or adverts you never installed.
Fan noise & heat
Loud fans and a hot case are often dust, bloat or a throttled CPU.
Updates keep failing
Windows or driver updates stall, roll back or never finish.
Four steps to a healthier PC
No drop-off, no courier, no waiting for days. Your computer stays right where it is.
Book online

Our service vs the Windows 11 PC Health Check app
Microsoft’s free app only tells you whether your PC can run Windows 11. It doesn’t fix anything — ours does the work.
Microsoft PC Health Check app
- Free to download
- Tells you if your PC can upgrade to Windows 11
- Doesn’t speed up your PC
- Doesn’t clean, repair or update anything
- No engineer, no support

Should I upgrade to Windows 11?
Proceed with care: test major upgrades on a machine you don’t rely on, and check that printers, scanners and cameras have up-to-date drivers. The free upgrade needs a compatible PC:
One fixed price. No hidden extras.
Pay at booking, then relax while we work.
