Complexities of Business IT Infrastructure

decisionsBuying and a computer and deciding on troubleshooting issues is really easy if it is for personal purposes only. After all, the only things you need to consider are your personal preferences, budget and convenience. When it comes to purchasing and maintaining computers for businesses though, the issue is definitely more complex with everything from the smallest details needed to be taken into account during decision making.

Some of the things you need to really decide on regarding your business IT infrastructure include your system requirements such as the appropriate operating system to use, your web hosting package, all other business software needed, and even the IT personnel that will maintain all these for you. On top of these all, you also have to factor in your budget and stay withing limits. You have to know if this is worth getting a financial loan and get the approval from your finance department.

With so many things to consider, the stress of troubleshooting PCs all day pale in comparison!

Video Card Errors – Part 1

video.jpgYou are browsing the net and you get tired so you take a break and return to a computer with no display, what do you do? First of all, don�t panic and see if the CPU is still functioning with blinking lights or the power LED (the green thingy that is always on when you use your PC). If it is blinking, the PC has turned itself off going into sleep mode, look for the wake-up key on the keyboard and press, you�re back in business. If it still fails, sorry but you�ll have to turn off the CPU (computer actually) by pressing the Power Button until the power led turns off and the fan stops humming. Disconnect all cables and connectors from the CPU and open the casing making sure you touch the case before doing anything else (this discharges static electricity which could fry expensive microelectronics like your motherboard, memory module, CPU, etc).

Scratched CD’s (Data, Driver and Software CD’s) Part – 1

sctratched.jpgThere are a lot of instances when we find ourselves looking for a driver or software installation cd that is needed to restore some function you have accidentally removed or uninstalled. Sometimes, they just seem to be hidden so good they defy all searching efforts but sometimes they are right in front of you but with tons of scratches due to your daughter playing with it as you accidentally left in on the computer table. These colorful disks are quite attractive to kids and will be dealt with when seen. Unfortunately, scratches that are deep enough to bend the laser can render a disk useless but shallow ones can be polished off. A warning though, this should only be tried as a last resort for this may also crack the disk or ruin it further.

Troubleshooting a Dead PC (Grounding Isolation)

bent.jpgModern boards use plastic stand-offs to which the board simply snaps into place or is fastened to by ties. Older PC casings use brass ones that need paper or cardboard washers for the task. There may also be an issue with the alignment of the board itself (there was an issue with Gigabyte boards sometime back that had the whole board sagging in one place of the other which prevented the memory modules from seating properly. Thanks to answersthatwork.com for the details ) Use plastic tie-downs where a plastic tie is used to pull the board into alignment to solve this type of problems.

PC Troubleshooting – What is Causing Your Computer to Run Very Slow?



Computer running very slow? There are millions of people just like you who are having to put up with a PC which won’t respond quickly and which will not load up very quickly at all. Fortunately, there are some easy ways to fix this problem which even a beginner can do.

The first thing you need to check for is the hardware of your computer. The ‘hardware’ that a computer has is basically all the components and physical pieces which make the computer work. The speed of your PC is directly determined by how much information your hardware can process at once, and the reason why many new PCs are expensive is because they can process a lot more information than older models, making them faster.

You should check the quality and specifications of your computer’s hardware to see if it’s able to run the system and software that you have on your computer. It’s often the case that many PCs older than 2 years need to have some upgrades in order to help them run as quickly as what they should.

Poor quality hardware is the biggest cause of a slow system but there’s another big problem that not many people know about. The other big reason why your computer might be running slowly is because of the “registry”. The registry is a database which stores information and settings for Windows, and is constantly getting corrupted and damaged. This makes Windows struggle to load a lot of the settings it needs, which makes it run slower and slower.

Not many people realize the significance of the ‘registry’ and hardly anyone actually knows it exists… but every time you use your PC, it’s being slowed down more and more thanks to an increasing number of registry files becoming damaged. This means that if you have a lot of corrupt registry files on your computer, you can actually make it run a lot faster by removing them all.

You can remove corrupt registry files with a ‘registry cleaner’, which is a software program designed for this job. Cleaning out these corrupt files will make your PC run faster and can even make it run like new. New computers run fast because they have new hardware and (more importantly) they don’t have any corrupt settings inside the registry, allowing Windows to open the files it needs instantly. This means that if you use a registry cleaner to scan through your system & clean up all of the damaged registry files, you could make your PC run as fast as it did when it was new.

3 Common VGA Drivers Problems, 3 Simple Troubleshooting Solutions



There are quite a number of common problems that computer users encounter with their video graphics array (VGA), and the most prevalent of these problems are often due to the VGA drivers. This article will list the top 3 common VGA problems, and 3 simple troubleshooting solutions to resolve them.

Problem one: Your monitor’s power LED seems to flash, but there is no image displayed on screen. This could possibly mean a couple of things, but before you do something stupid like smacking the monitor hoping it will somehow jar it back to life, check to see if the connection to the computer is ok.

Sometimes even when things are all connected there may still be problems. This would most likely mean that there is something wrong with the digital/analogue connection, and you will have to look into the problem. It could be the cable itself, or it could be the port. It could also mean that you may need to have a converter, depending on how old or how new your monitor is. Not everything is a problem with the driver though, and sometimes hardware also plays quite a part in it; so you need to look at this problem from both angles.

The problem could also lie with your graphics card hardware and its drivers. One thing that you need to have is the latest drivers for the graphics card. By doing so, you can figure out the problem with ease, especially if you can eliminate drivers as being the sole cause of the problems.

First things first, make sure that you are able to verify the graphics card compatibility with both your system and the monitor. If there is still an issue with the display, then what you need to do is to get the latest drivers. You can do so by simply going online and visit the manufacturer’s website and download the drivers from there. More often than not, this is enough to solve the problem.

But if it still doesn’t work, do not worry, most of the time, blank unresponsive screens would more than often mean that you have installed a previous, outdated version of the drivers. What you can do is also to use force ware drivers, which are universal drivers for graphics card that activates the chip the same way your manufacturer has designed it. In fact, there is almost no difference when it comes to both drivers, so you can use both.

One thing unique about the display environment of the PC is that there is another set of drivers that come into play, which both facilitates and augments the capabilities of your graphics card and this is called the Direct X technology. This is a technology released by Microsoft, and a lot of the architecture built around the display driver is done so in reference to the versions of Direct X available.

Therefore, it is also crucial for you to have an updated version of Direct X, whose drivers are available on the company website and sometimes comes packaged with new games and new graphics cards that are purchased.

With these 3 common problems and 3 common tips to use, you will be able to route around many of the display driver problems that are plaguing people all over the world.

Intel 8088 That Started the PC Revolution



The 4004, the very first microprocessor kind of just happened. The designers started out to design a chip set for programmable calculator rather than a processor. They designed a general purpose processor instead. That led to several other improved microprocessors including a 16 bit one the 8086. Then in a kind of step back Intel produced a microprocessor a year later, on July 1979, 8088. This was internally the same as the 8086, a complete 16 bit processor, yet external interfaces were all 8 bits. Looking back that might look like a retrograde step. IBM went ahead and used the processor in their IBM-PC product and the rest, as they say, is history!

If you looked at the way a slew of processor coming out of the major manufacturers and the way support chips catch up, it would be hard to believe it used to take time for the support and peripheral chips to catch up. One of the decisions PC manufacturer wanted to implement with the PC, was to use existing technology as far as possible. They went ahead and used the 8088 for that reason. With the existing support chips in 8 bit yet the internal architecture of 16 bit gives you benefits to an extent. At least it would be better than using a processor that is 8 bits inside out. The 8088 had a 8 bit data bus instead of the 16 bit bus of the 8086. Internal 16 bits registers and the 1 MB addressing capability was retained.

The 8088 CPU took two read or write cycles to read or write 16 bit data instead of one as in 8086. But these bus changes made it compatible with 8080/8085 support chips. The 8085 related chips were available in a wider selection, they were stable and also priced much lower than the newer 16 bit support/peripheral chips.

One would think it was logical to use a 16 bit processor for the PC. That actually came later. Processors in 16 bit were already available. The 8086 was around for a year already at the time 8088 was announced. The PC came about couple of years after the coming out of 8088. Motorola 68000 was on the scene too. Many considered the M68000 processor a very well designed 16 bit processor, designed from ground up. Existing, stable technology was the key decision about the PC and they stuck to it rather than go with newer technology.

At this time the processors still did not accommodate the complexity of floating point math operations in hardware. 8086 introduced a numeric c-processor, the 8087 that works with 8086 to provide floating point operations to the 8086. Interestingly the 8088 too could work with the 8087 and provide the math support. Thus there was no restriction that the PC could support office productivity applications only. As it happened later, scientific applications like the AutoCAD too would run on the PC. The PC was ready for the applications revolution on either genre and look what happened!

Audio Problems – 3 Tips on Troubleshooting Realtek Drivers



If you ever encounter a problem with your computer’s audio, one of the first things you should do is check the system bios and see if there is any problem with it. You need to understand that the bios is not a perfect piece of software and it is prone to problems as well. This means that it is prone to problems just like anything else in the computer. What you need to do is to either flash the same bios within the motherboard again or download the latest one from the website of the manufacturer.

All you need to do is to download the new bios and flash it with the instructions given to you in the manual. You should know that each motherboard has a different way of installing new bios. You need to be careful here as you do not want to wipe it out of your system in altogether. Messing it up could mean a painful and complicated move of realigning the jumpers and recalibrating your entire system again.

Also, another thing you can do is to update the Realtek drivers themselves. The drivers that you might be getting from the package might be old and untested with the current configuration of the computer you have now. Understand that technological advancement progresses at an insanely quick rate in today’s world of computing. In order to keep up with the constant evolution of technology, drivers will be updated often because of the changing digital environments.

As new programmes and new software are released, manufacturers often have to test and retest the code of their drivers and then change them accordingly to ensure that there is a high level of compatibility for all consumers. Knowing this, you need to be able to ensure that you have the latest drivers. To do this, you need to find them either online or through third party sources. Of course, the best ways to get them online is from the website of the manufacturer of your choice and just download them into your computer.

Last but not least, you need to be careful when you do install new software or hardware, especially when they are in the multimedia range of goods. Especially when you have an all in one or sound card that you wan tot install, you need to understand that there are certain procedures involved in the process of installing them.

One of them is that you need to deactivate the onboard chip to make sure that the installation goes smoothly and that you can eliminate all possible conflicts. This ensures that the installation process is very smooth and that no other problems might occur at the same time as well.

These are the three ways in which you can ensure that your audio driver issue with Realtek does not cause problems for you. Of course, do note that these are general tips – problems that are way more involved may require a more advanced technical expertise, depending on the severity of the issue.

Understanding Blue Screen of Death

 

Blue Screen of Death. Just the name is terrifying! It is likely that if you’ve used Windows that you’ve also encountered this blue screen STOP error. It happens whenever your computer senses a software, hardware or driver error which will not allow it to continue operating properly. It can happen anytime for any different reasons. Before you have a heart attack, here’s a beginner’s guide on how to deal with BSOD

The first step is trying to reboot your computer. Sometimes, all it needs is that and you will have recovered. On other more complicated times, you may need to troubleshoot more. All BSOD comes with clues. Take your time to read because it will contain what you need to do. Most of the time it will tell you to restart your computer. (Do that) Otherwise, go into safe mode. From there you can get into “My Computer” and right click on the “c” select the tools tab and do a defrag and schedule a disk check – check both boxes in disk check – one says “check for errors” the other one say “attempt to repair”
