Protect your Windows COA

Being able to read the license number on the windows Certificate Of Authority is essential if your laptop requires reloading.

Microsoft have stopped adding the glossy cover so I am seeing that the Vista and Windows 7 COAís are becoming unreadable quite quickly. I recommend that you protect these by applying clear tape over the number to ensure that it does not deteriorate over time. I do this as a rule myself whenever I notice that one is becoming worn out.

Surge Protection

When you live in Wiltshire you will know that power is not always reliable. You are strongly advised to use an anti-surge board to protect all electronic equipment and if the data is critical you might buy an uninterruptible power supply (UPS).

A surge protection board looks like a power board but has built in protection against surges. Cost of these is around £15.

A UPS is essentially a battery with a circuit that detects mains failure and informs your computer so that it can shutdown in a controlled manner.

Why you should leave your modem on

Stricly speaking it is is a modem/router as it does both jobs.

Apart from the time taken for the modem to connect again, you may find that you never get the fastest connection speed possible. Many modems (including the BT Homehub) have an algorithm which attempts to improve the speed of your connection over time. Each time you turn it off it begins all over again. So if you turn it off every day you will never reach full speed.

Why you might need to reset your modem

Sometimes it is necessary for your Internet Service Provider (ISP), for example BT, to turn off the service for maintenance reasons. This is usually done overnight so you do not have downtime during the day.

Your modem will retry a few times to connect but if the service is down for an extended time the modem will give up and you will still be unconnected when service resumes.

To solve this problem turn off the modem and then turn it back on again. The modem will try to connect and you will be reconnected. Of course, if not you should call PC Doctor Dave on 01672 564293.

Why you should not unplug your PC

Unplugging or turning off the plug socket for your desktop PC may not be a good idea and may end costing you money. This is not to say you should leave it switched on either. Shutdown or hibernate but do not unplug. The desktop PC has a small battery inside which powers the BIOS when no mains is connected.

Normally these last for years but if you turn off the mains it will go flat much quicker (still many months of course).

When the battery goes flat most PCs just lose the time but a few lose ALL their settings and will not start !

Connecting a printer to Windows 7

Windows 7 is very good at detecting and installing new devices and if you attach a printer it will install it. However, especially when dealing with all in one printers, the installation may not install the printer correctly. So, you should always load the CD supplied BEFORE connecting the printer. Only when the install process indicates that it is time to connect the printer should you do so.

Another word of warning. If the CD does not state the version of windows that you have, you should download the latest software.

Look after your laptop

The price/performance of a laptop is always worse than a desktop simply because of miniaturisation and the consequent need to keep the machine cool.

Heat is the enemy of a computer and this is especially a problem with laptops. Most laptops have the fan inlet at the bottom of the machine and when you use it on your knees or on any kind of material surface (like a bed), it will be blocked to some degree. You will also find that over time there is a build up of fluff inside the fans small outlet fins. Click here to see some examples

Treat the battery of your laptop just like you do for your mobile phone. It is vital to discharge fully before charging (especially when new) to get maximum battery life. I recommend that your remove the battery altogether (or switch off charging if this option is available in power options) when you use it on mains power for extended periods.

Hoax phone calls

You may soon get a call from an Indian person claiming to be from Windows (you might be immediately suspicious as the company is Microsoft) and telling that you have had a problem with your PC. They also might say Norton, McAfee, Grisoft etc etc.

BE WARNED THIS IS A SCAM. DO NOT PAY ANY MONEY.

In all likelihood you have a virus which has allowed them to get details about you making them sound very genuine. If you have already been scammed and you entered credit card details on your PC you should contact your bank immediately.

 × 

Hoax emails

I keep getting Ďhelpfulí mails from various people warning me about various issues. If anyone sends you an email that tells you a virus is coming or some problem with your mobile phone and you should forward the warning, please do not bother.

Look up the title of the email in Google instead (adding the word hoax) and you will discover that it is a hoax like all the others.

 × 

Peer to peer programs

When you use some peer-to-peer programs like uTorrent, Vuze, BitLord & Sopcast that let you illegally download from and share files with other people, you are increasing the odds that youíll get a virus on your computer. There are safe places to download files, but programs like these are not those kinds of places. As nice as it can be to share files and watch live television from all over the world, it isnít worth it to deal with a questionable, and mostly illegal, operation.

Increasingly I am finding that many of the PCs that I get in with a virus has one of these programs. Be warned.

Microsoft Office File Format conversion

Do you keep getting email with an attachments that you cannot read ?

Convinced you need to upgrade Microsoft Office to 2010 ?

Think again !

It seems like Microsoft donít want you to know it but they have released a converter for the old versions of word (and excel etc) to read the new document format. Whatís more itís FREE !

Just go to this microsoft site, download and install.

Virus Protection

Avoiding downloads from sources you are not 100% certain of is the best way to prevent virus infections. You do need to have protection but there is no guarantees with any of these products.

In fact the free products such as Microsoft Security essentials and AVG are often higher in league tables than the paid for products such as Norton, McAfee & Kapersky. Remember that the more popular a product becomes the more sure that a virus maker will ensure his virus gets past it !

Most paid for products have a firewall and this might seem like a great idea but in fact all you are doing is replacing the (perfectly acceptable) windows firewall with a third party product. When Microsoft make changes you can be sure they will test their own firewall but can you be so sure about the third party products ?

My vote is currently for Microsoft Security Essentials mainly as there is no paid version and therefore no adverts but that may change.

Why I do not recommend Internet Explorer

What are all those windows updates for ? Yet another security update ? Because everyone with a PC has Microsoft's Internet Explorer, this is the target of a large proportion of hacker/virus/spy-ware attacks and so using ANY other browser is likely to be more secure.

If this is unclear, the browser is the program (tool) that you use to read web pages (eg the google search page).

I prefer and recommend Mozilla Firefox as I find this is the fastest and is clear of adverts but some other popular choices of browser are Opera, Chrome (Google) and Safari (Apple).

Making your PC faster

Unless there is a fault or a virus your PC runs slowly because it is running too many programs automatically. Do you think adding another will help ?

Having ended up with lots running you may need to call me to get rid of them.

However, you can avoid these by being more careful when you install or update software.

Although the vendor might recomend that you select a custom option, I advise you to pick the option for advanced users. This is just the same but you can view what is going to be installed. Having selected the advanced install, when you see options that are not essential (eg toolbars), remove them.

Registry cleaners are easy to create and lots of vendors have jumped on this bandwagon as an easy way to make money. In rare cases they have uses but mostly they will make no difference and if you are unlucky they can cause serious problems.
