You know the moment. Your screen is bright blue and there are all types of dire warnings on your screen about date loss and malfunctioning programs. Some people refer to this as the blue screen of death. This is not as common as it once was, but things still happen. Those without virus protection are most vulnerable because viruses that wipe out data, important data, are still out there and they strike every day. Hopefully, if this happens to you, you have your recovery disk for Windows XP and you know how to use it...or them.

When you get a new computer with Windows XP, or perhaps you are buying a used model, you have to make sure the recovery disk for Windows XP is included. In many cases, there may be more than one disk, so make sure they are all there if that is the case. You may take excellent care of any computer you own, but things can go wrong that are out of your control no matter how well you maintain your machine or how good your virus software may be. It is always better to be safe and have the disk on hand in the event you need it.

Back in the day, it used to be that if you kept books or if your accountant kept books for you, you basically did it on big fat ledgers. There were receipts and vouchers to keep track of, dozens of columns on every ledger page and so on. When business accounting software first made an appearance a couple of decades ago, small businesses had this way of scoffing at how they would never need anything like this. It was just pencil and paper for them as usual.

These days though, it's far easier and cheaper for any small business to use business accounting software than it would be for them to hire someone to laboriously use the old method (this is is seeming that you could even find anyone willing to do this anymore). But that isn't even just it. Business accounting software can make human error a thing of the past.

It can put all kinds of graphs in front of you at the touch of a button and show you things about how your business is doing that you would never have known otherwise. You can get sales reports for a certain period of time at a moment’s notice, you can see three kinds of graphs for how quickly inventory is moving, it can show you what kinds of things you do that are profitable or not so much, and so on.

As much as Apple has tried and succeeded at making the iOS environment extremely easy and intuitive to navigate, for someone coming over for the first time from, say, the Windows environment, it can take a little getting used to. For instance, people who have their first taste of Apple in an iPad often fret over how to transfer music from computer to iPad and not a race anything. It's actually quite easy, once you get a hang of how Apple sees these things.

On non-iDevice phones, MP3 players and so on, you basically just connect whatever it is to the computer, and you see it open up like it's just another folder on the computer, they can do whatever you want with the music files in there. You certainly could use Windows media player or any other music player to sync your MP3 player so that only those songs get added that weren't there the last time you connected to the computer.

But this isn't the primary way of going about it on the iPad. On all of Apple's portable devices, syncing the device to iTunes is the default way to go. You certainly could use your iPad or iPod like a mass storage device and simply move files back and forth. That isn't the the way they would prefer you to dis it though with. You have to do with through Apple’s media player software, iTunes for the best experience.

Setting up a home network, even if networks do accomplish fantastically complex tasks, doesn't ever seem all that difficult a thing to achieve to most people. We all seem to know kind of instinctively what home networks basically do and how merely plugging wires in the right places gets things done. For this reason, setting up a home network, especially in a small home with perhaps three computers or so, isn't that big a deal.

A home network for your computers to plug into can be either wired or wireless. Surprisingly, going wireless is cheaper. For three or four computers in a home, you wouldn't have to spend more than $100 all put together, if that. With a wired system, you'd have to buy a bundle of wire and string through the house and aesthetically pleasing way. That could cost quite a bit.

Once you've set everything up, any computer in your house should be all to touch base with any other network-enabled device in the house – a computer, a flatscreen TV, of music system a mobile device, a printer or anything – everyone should be able to share resources and data or anything else.

If you are looking for a new printer that can handle all of your needs, including printing high quality photographs, you should make sure you do your homework. There are many models out there that print, fax, scan, copy, and do photographs, but they are not all created equal. Some great ideas have turned out to be duds and some are just too expensive for the average person. When you want to shop, look for photo printer reviews before you ever set foot in any store that sells electronics and computer supplies. You may find that what you thought you wanted is not a good option, or that the one you have is discontinued for a very good reason.

One thing that you want to check out when you find photo printer reviews is the price of the ink and how much that particular model tends to use per picture. Kodak makes some great ink that is low cost, but some people have had a lot of problems with their early photo printers. On the other hand, a different model may work better, but the price of the ink alone makes it impossible for most people to print out a decent amount of prints at home without breaking the bank. Ink prices vary so make sure you factor these in when you shop.

There was a report recently about how young people these days, while they do watch television shows like everyone else, like to watch those shows on their computers or their cell phones. More and more, television manufacturers are coming to understand that people don't just want to connect their TVs to their cable or satellite dish and watch stuff as it comes. They want to watch stuff that comes on their computers on demand., But they do want their TVs – to use as a monitor so that they can connect their laptops and iPads and cell phones to them and watch their on demand content on those big screens. If you want to do the same, but you're not quite as comfortable with all these new things the way young people are, here's how to connect a laptop to a TV.

Here's the thing – it doesn't take much to connect a laptop to a TV. The connections are easy. You just need the right kind of cable, and your three-quarters the way there. If your laptop is somewhat recent, you're sure to have an HDMI port on there. Chances are though, that your laptop isn't that recent, and you might not have one of these. What you might have instead is regular old-world VGA connection or, if you're lucky, a DVI connection.

If you have one of these, you're in luck. You get adapter wires that have an HDMI connection on the one side to plug into your TV, and a DVI or VGA connection – whichever you have on your laptop – on the other end. All you need to do is to plug each side into the right port, and you're practically there.

It doesn't matter if you just want a keyboard to pick notes out with one finger. If you go out to the music store, you will have the hardest time buying a keyboard because you will be completely spoiled for choice. If your skill level warrants the use of all 10 fingers, you can knock yourself out silly at the store – there's an embarrassment of choices any keyboard buyer. If you're on the market for a keyboard, here's a little primer on what to look for the best results.

No matter what skill level you're shopping for there are a few basic kinds of keyboard features you need to consider. First is the first is to do with how many keys you want on your keyboard. They make tiny models with 25 keys, meant for use with user-friendly music-making computer programs like Ableton Live and FL Studio, through to compact models with 49 keys for children and for those who like to take their keyboard around and make a huge ones with 76 or 88 keys meant for people who are really skilled at playing the piano.

But most people just like to buy the 61 key standard. 61 keys happen to be just right for the learning musician and the serious amateur. 61 is neither too many there were too few. Goldilocks would love it.

Whenever I have a phone issue or my computer stops working, I do everything in my power to figure out what is wrong and if I can fix the problem myself. The reason for this is that I really hate to have to deal with technical support services with a passion, and I have had many unpleasant experiences that have made me this way.

The first phone call that I remember was one that my father made. He was on with one of the technical support services for an Internet provider he used to have. Evidently, the call was forwarded to a worker in India who could not hear my father. My father had the quintessential quick Irish temper, and let's just say that things got ugly very quickly.

He had just gotten out of the hospital, where he had been for more than two months, so needless to say that we were all happy he was home. As a matter of fact, we encouraged him not to call the technical support services for this particular company because we had dealt with them and knew what they could be like. My father was wearing a robe, short pants, and a top hat my sister had put on him as a joke, that apparently my father forgot that he had on.

If you own an online business or if you just have a website, you could often need to collect a bit of information from your visitors to know more about the kind of tastes your audiences have. You could need simple contact information or you could need more detailed stuff about everything to do with a visitor. Whatever kind of information you do collect, to create PDF forms to have your visitors fill it out would be a great way to do it.

You've seen websites show you PDF forms when they wish to collect information, haven't you? They can look aesthetically pleasing, they come with some assurance of data security, and they just look professional. Far more so than anything that could be made on Microsoft Word.

Adobe Acrobat Professional is of course your first choice of software to create PDF forms on. Any forms created on this software, any visitor on your website can easily download, fill out and return to you through e-mail. All they need is Adobe Reader on their computer, which is free. Anyway, everyone has it already.

If only cars were as simple to maintain as computers were. If all you had to do to change the oil or to check tire pressure was to press a couple of buttons sitting in the comfort of your seat, no one would ever let any maintenance get out from under them. Oddly enough though, they do let quite a lot get out from under them when it comes to computers. The thing is, computers don't need any mechanical maintenance. You don't need to oil your hard drive or put your i7 processor in the mineral oil bath to clean up the joints. Whatever maintenance you need to do is all in the software. People don't take software very seriously. This little computer maintenance checklist should help you identify what spots need a spot of care from time to time.

Have you ever noticed how when you first buy a computer or when you do a fresh install of the OS, that it runs in an inexplicably clean and smooth way? The moment you install your first program though, things become less than smooth in some hard-to-define way.

Funny how people talk about smartphones like they are a new concept. The BlackBerry has been around for at least 10 years now. Even so, perhaps it would be accurate to treat smartphones like a new concept because it was only in 2008 that the App Store actually took off. The idea that you could have an actual place to go to for programs to put on your phone like it was computer is a very recent concept. Still, app developers have pounced on the concept and really got it off the ground.

Apple's App Store has about a quarter million apps and billions of downloads. App developers are trying everything they can think of to bring original ideas for apps into existence. The app concept is generally stage yet. The gold rush for workable app concepts really could be great now at a time when not all the concepts have been discovered yet.
