When your desktop or laptop computer fails, and you need it repaired, you will have to contract with a computer technician. But if you don't have the time to visit a computer repair shop, you can use a mobile computer technician who will come to your home or office, and specialises in handling a number of hardware and software issues related to computers. Here are some services these experts provide.

General Computer Repair—Mobile computer technicians can diagnose and fix many general computer issues. The most common reason computers fail is a hard drive problem. Whether your hard drive is failing to boot, or it works intermittently then shuts down your computer, a mobile computer technician can solve the problem.

The usual solution is for the technician to install a new hard drive and operating system to get you back up and running. Some hard drives can be restored using a backup or cloned versions of the drive, and some hard drives can be wiped clean and reused with the installation of an operating system.

Other common repair issues include a faulty motherboard, fan motors that have stopped working, which causes your computer to overheat and faulty batteries that need replacement.

Upgrades—You can also call a mobile computer technician to install upgrades on your computer. With technology moving at such a rapid rate, it's vital for you to have the latest hardware and software to ensure that your computer runs at peak efficiency.

Whether you want to upgrade your memory capacity, install a bigger hard drive, add a new graphics cards for video game play or add a suite of anti-virus programs to your computer for additional security, a mobile computer technician can come to your home or office and perform these upgrades for you.

Data Recovery—When your hard drive crashes, or you computer is the victim of a virus that wipes out all your data, your biggest fear is that you've lost all the information on your desktop because you failed to back up the information. But a mobile computer technician may be able to recover that information through a data recovery program.

If the technician is able to recover your data, he or she will place it on a portable hard drive, and then recommend the installation of an automated recovery program, so that you won't have to worry about losing data in the event that your computer crashes again.

Many mobile computer technicians are available seven days a week to visit your home or office, and emergency technicians sometimes work 24 hours a day, but will charge high fees for after-hours service. Contact a few such as Nanotech Computers-Brookvale to get an idea of how a professional can fix your computer.
