One of the most frustrating experiences when using a computer is when it suddenly and often inexplicably develops a problem. Many problems can be fixed by a reboot, so before doing anything else, you should shut down your computer and any peripheral devices that may be attached to it (i.e. printers, cameras, music players, etc). Then turn everything back on in a controlled manner - restart your computer first, wait for it to finish starting up and then turn back on your peripheral devices one at a time.
If you are having trouble connecting to the internet, it is also advisable to power off your router (or modem), leave it switched off for a couple of minutes and then turn it back on again. Wait 5 minutes for it to finish going through its start up procedures and then see if the internet is working again.
If you have more than one device that can access the internet, see if they still have a working connection. If all devices are 'down', it may be that there is a problem with your telephone line, in which case you should contact your Internet Service Provider (e.g. BT, TalkTalk, Sky) for help.
If none of the above simple steps fixes your problem, then please call me or email me with a description of your problem, leave your contact details and I will get back to you as soon as possible.
I may be able to give you an idea of how long it will take to fix your problem prior to visiting you, but it is often difficult until I have had a chance to investigate first hand what is going wrong. It typically takes me between 1 and 3 hours to resolve most problems, depending on what I find.
Please note that if your computer is physically damaged (e.g. broken screen, faulty hard drive, won't power up, etc.) then the likelihood is I won't be able to help you. The best I could do is give you a diagnosis of the problem and make a recommendation as to where and how to get it fixed. I could collect your PC or laptop, arrange for it to be repaired and return it to you should you so wish. In many cases, once a computer goes beyond a certain age, I would advise buying a new one rather than have it repaired, both on grounds of cost and the advantages you will get from faster more reliable new technology.
