Should I Fix My Computer or Buy a New One?

Unless you are a recent entrant to the world of computers, this is probably a question you’ve asked yourself before. After all, if your computer doesn’t work properly, you may have a strong instinct to throw it out and go get another one but keep wondering if it is worth fixing. This article is intended to help you decide which of these paths you should take to get a PC up and running so you can go about your work or play.

You may be thinking that since this is a computer repair technician writing this article, I’m going to tell you that in almost every case, you should fix your computer rather than get a new one. Not so. Just as there are a host of reasons to fix your computer, there are plenty of reasons to buy a new one instead.

Although the costs of consumer computers are nowhere near the costs of new cars, those of you who have had to decide whether to fix an older automobile or buy a new one may find it helpful to think about that process because it is similar. I would advise you to make two columns and write the reason to buy or fix in the appropriate column.

If you think it through this way, you will find yourself coming to a reasoned and reasonable conclusion. Also remember that if another person has your same PC model and the same problem, what he or she decides does not make their decision good for you. Keep in mind that there is not a right or wrong answer, only the best answer for you. While this article and others can help your decision process, the best answer for you is something only you can decide. Be wary of people who are certain that they know what you need.

Let’s look at some reasons to repair your current computer:

• Budget – Although the extra expense can be worth it, buying a new PC is USUALLY more expensive than fixing your current computer. If you are on a tight budget or are just a frugal person, fixing most problems may be best for you.

• Data – This second reason is related to the budget item. Whichever route you decide to take, you can (usually) keep your pictures, documents, music, emails, business files, and important personal information. It is easier, though, if you are keeping your computer because if you get a new PC, you will have to pay someone to transfer that information to a new PC. Many of you can do this without problem but not everyone can. Also, if your PC won’t boot to Windows and the data has to be extracted from the computer, most of you will need someone to get the data off the hard disk, which means you will be paying both for a new computer plus a service fee to a computer technician.

• Applications – If you get a new computer, you will also have to reinstall all of your applications. Some can be downloaded, like iTunes or Adobe Acrobat Reader. Any that you paid for, such as Microsoft Office, however, will likely be on CD/DVD. They must be installed from this media, along with the product key that came with them. My experience has been that both organized and unorganized people have a tendency to lose application CDs, particularly if they have had their computer for several years. Before buying a new computer, gather all your application installation CDs and make sure you have a disc for all the applications you use. You may be able to avoid this process and have all your applications as they were if you get your computer fixed. However, it should be noted that if the proposed fix to your current PC is to reinstall Windows, this issue is moot because all of your applications will have to be installed on a new Windows installation, just as on a new PC.

Computing Crunch Power

It has been postulated that our reality might in fact be a virtual reality. That is, some unknown agency, “The Others”, have created a computer simulation and we ‘exist’ as part of that overall simulation. One objection to that scenario is that in order to exactly simulate our Cosmos (including ourselves) we would require a computer the size of our Cosmos with the sort of crunch power that could duplicate our Cosmos on a one-to-one basis, which is absurd. The flaw is that realistic simulations can be made without resorting to a one-on-one correlation.

WHY ARE WE A SIMULATION?

Here’s another thought on the Simulation Hypothesis which postulates that we ‘exist’ as a configuration of bits and bytes, not as quarks and electrons. We are virtual reality – simulated beings. Here is the “why” of things.

Really real worlds (which we presume ours to be) are simulating virtual reality worlds – lots and lots and lots of them – so the ratio of virtual reality worlds to really real worlds is lots, and lots and lots to one. That’s the main reason why we shouldn’t presume that ours is a really real world! If one postulates “The Other”, where “The Other” might be technologically advanced extraterrestrials creating their version of video games, or even the human species, the real human species from what we’d call the far future doing ancestor simulations, the odds are our really real world is actually a really real virtual reality world inhabited by simulated earthlings (like us).

Now an interesting aside is that we tend to assume that “The Other” are biological entities (human or extraterrestrial) who like to play “what if” games using computer hardware and software. Of course “The Other” could actually be highly advanced A.I. (artificial intelligence) with consciousness playing “what if” scenarios.

SIMULATIONS AND THE NEED FOR COMPUTER CRUNCH POWER

Anyway, each individual simulated world requires just so many units of crunch power. We humans have thousands of video games each ONE requiring a certain amount of computing crunch power. There may be in total is an awful lot of computing crunch power going on when it comes to these video games collectively, but what counts is the number of video games divided by the number of computers playing them. Not all video games are being played on just one computer at the same time. If you have a ten-fold increase in video games, and a ten-fold increase in the number of computers they are played on, there’s no need for ever increasing crunch power unless the nature of the game itself demands it. Video games today probably demand more crunch power than video games from twenty years ago, but we’ve to date met that requirement.

Now if a really real world created thousands of video games, and the characters in each and every one of those video games created thousands of video games and the characters in those video games created thousands of their video games, okay, then ever increasing crunch power within that original really real world is in demand. That’s not to say that that ever increasing need for crunch can’t be met however. But that’s NOT the general scenario that’s being advocated. For the immediate here and now, let’s just stick with one really real world creating thousands of uniquely individual simulated virtual reality worlds (i.e. – video games). Ockham’s Razor suggests that one not overly complicate things unnecessarily.

That said, a variation on Murphy’s Law might be: The ways and means to use computing crunch power expands to meet the crunch power available and is readily on tap.

Sceptics seem to be assuming here that if you can simulate something, then ultimately you will pour more and more and more and more crunch power (as it becomes available) into that which you are simulating. I fail to see how that follows of necessity. If you want to create and sell a video game, if you put X crunch power into it you will get Y returns in sales, etc. If you put 10X crunch power into it, you might only get 2Y returns in sales. There is a counterbalance – the law of diminishing returns.

Video gamers may always want more, but when the crunch power of the computer and the software it can carry and process exceeds the crunch power of the human gamer (chess programs / software anyone), then there’s no point in wanting even more. A human gamer might be able to photon-torpedo a Klingon Battlecruiser going at One-Quarter Impulse Power, but a massive fleet of them at Warp Ten might be a different starship scenario entirely. Gamers play to win, not to be universally frustrated and always out performed by their game.

It makes no economic sense at all to buy and get a monthly bill for 1000 computer crunch units and only need and use 10.

But the bottom line is that computer crunch power is available for simulation exercises as we have done. Anything else is just a matter of degree. If us; them; them of course being “The Other” or The Simulators.

The History of Computers

While computers are now an important part of the lives of human beings, there was a time where computers did not exist. Knowing the history of computers and how much progression has been made can help you understand just how complicated and innovative the creation of computers really is.

Unlike most devices, the computer is one of the few inventions that does not have one specific inventor. Throughout the development of the computer, many people have added their creations to the list required to make a computer work. Some of the inventions have been different types of computers, and some of them were parts required to allow computers to be developed further.

The Beginning

Perhaps the most significant date in the history of computers is the year 1936. It was in this year that the first “computer” was developed. It was created by Konrad Zuse and dubbed the Z1 Computer. This computer stands as the first as it was the first system to be fully programmable. There were devices prior to this, but none had the computing power that sets it apart from other electronics.

It wasn’t until 1942 that any business saw profit and opportunity in computers. This first company was called ABC computers, owned and operated by John Atanasoff and Clifford Berry. Two years later, the Harvard Mark I computer was developed, furthering the science of computing.

Over the course of the next few years, inventors all over the world began to search more into the study of computers, and how to improve upon them. Those next ten years say the introduction of the transistor, which would become a vital part of the inner workings of the computer, the ENIAC 1 computer, as well as many other types of systems. The ENIAC 1 is perhaps one of the most interesting, as it required 20,000 vacuum tubes to operate. It was a massive machine, and started the revolution to build smaller and faster computers.

The age of computers was forever altered by the introduction of International Business Machines, or IBM, into the computing industry in 1953. This company, over the course of computer history, has been a major player in the development of new systems and servers for public and private use. This introduction brought about the first real signs of competition within computing history, which helped to spur faster and better development of computers. Their first contribution was the IBM 701 EDPM Computer.

A Programming Language Evolves

A year later, the first successful high level programming language was created. This was a programming language not written in ‘assembly’ or binary, which are considered very low level languages. FORTRAN was written so that more people could begin to program computers easily.

The year 1955, the Bank of America, coupled with Stanford Research Institute and General Electric, saw the creation of the first computers for use in banks. The MICR, or Magnetic Ink Character Recognition, coupled with the actual computer, the ERMA, was a breakthrough for the banking industry. It wasn’t until 1959 that the pair of systems were put into use in actual banks.

During 1958, one of the most important breakthroughs in computer history occurred, the creation of the integrated circuit. This device, also known as the chip, is one of the base requirements for modern computer systems. On every motherboard and card within a computer system, are many chips that contain information on what the boards and cards do. Without these chips, the systems as we know them today cannot function.
