How can we help you?

PC hardware failures

Perhaps your computer is playing up and you are not sure why. It could be a hardware issue such as a damaged hard drive, faulty RAM or another component that has failed. Or perhaps incompatible hardware. Whatever your problem, we can diagnose and repair.

Laptop repairs

Dropped your laptop or spilt something on it? We can fix most makes and models, including ACER, Dell, Toshiba, Samsung and Sony - broken screens (from £80+VAT supplied and fitted), noisy fans or overheating, replacement keyboards/track pads, and hinge replacements are commonplace.

Solving software problems

Perhaps your computer has a 'blue screen of death' or other error message that you cannot fix easily or maybe it's sluggish. With our experience of Windows 7/8/10 and servers we can resolve the issue - often remotely. Let us spring clean your computer, install updates or a fresh copy of Windows.

Internet issues

Almost everyone expects a fast, reliable Internet connection and when it plays up can be highly inconvenient. We can advise the best ways to get the most out of your Internet connection be it different hardware or software optimisation.


We can offer you low-maintenance, competitively-priced solutions for all networking problems -- from hooking up a few computers in your house to full server-centric network installations.

Keeping you safe

Removing and securing systems against viruses, spyware, and other malicious software.
