Essential Facts to Know About Computer

Computers have become the part and parcel of every business unit, and as these are sensitive gadgets that often need repair, upgradation, and periodic maintenance. Your business is no exception for sure but do you know how you can find the best computer maintenance and repair support? If you are not fully aware of it, know the essential details of repair and maintenance before you hire a service and verify the needs with your available resources.

Check if service provider is endorsed by manufacturers’ certification

Some computer repairs facilities enjoys their manufacturers’ endorsement as preferred service providers. Check if the service provider you have selected is an authorized and preferred counter for computer repairs. Also check if the technicians working there have done their course on computer repairing. As computers are getting complex every day, only trained technicians can manage repairing job with professional proficiency. Specifically you should ask if the repair facility is equipped enough to offer servicing for the brand of computer you are working with. For example, if you are using Dell, check if the technicians are Dell certified.

Faster turnaround time

When you need repairing service support, it is obvious that you want to get the job done fast. You need to clarify with the repair facility if they can get their job done in short turnaround time. Before speaking to your shortlisted vendor, you also need to check at random with other repair shops about the average repair time and accordingly evaluate if your vendor is offering the right turnaround time. Alternatively, ask your service provider if they are capable to offer you one-day repair service.

On site repairing support

Although computer and laptops are portable, but it always wise to call an onsite support service because it saves time and you need not to take away your system out of your premise. Ask your repair service provider if they can offer you on site service: it will be a better option for you.

Service warranty is a must thing

Before you find and finalize your computer repair service provider, check if they offer you service warranty. Unless service warranty is offered, there is high chance that service quality of your vendor can be compromised. Additionally check if the company offers replace guarantee of spare parts if anything they damage during repair work. According to market standard, repair facilities offer 6-12 months warranty; without service warranty long term cost efficiency of your computer maintenance may not stand profit yielding.

Service charge should be affordable

Service charge and its affordability is one of the vital factors for selecting a vendor for computer repairs and maintenance. Check the service charge for the repair jobs proposed by your vendor. Unless it is moderate and justified, in the long run, it might get difficult for you to use a costly service. Also check if the service provider is available 24×7 because you do not know when you may need the support.

These are the essential facts you need to know about computer maintenance and repairs because a service provider with all these facilities can only be the best option for your business use.

Questions about Computer Sound Problems

Computer sound problems can be very frustrating. The truth is that troubleshooting sound problems is a little different than most other troubleshooting because the usual troubleshooting approach of stripping the PC down to bare essentials often doesn’t apply.

The following questions and answers help highlight what can go wrong and suggest the approaches you can use to diagnose and repair the problem.

Question 1: I only hear sound out of one speaker. What’s happening and what can I do?

Answer: You can troubleshoot this by isolating the problem to the sound card/computer, cable, or speakers. You can test your speakers on an alternate source, such as a Walkman, portable stereo, or other audio source.

If the test works (and you used the same cable), the problem is probably in the computer or sound card setup. If the test fails, try a different cable. If that works, the cable is the problem; otherwise, you might have a problem with the speakers.

Check the cabling between speakers and make sure the balance control is set properly. If your speakers have independent power sources, make sure both are working (don’t forget that batteries fail).

Question 2: Why does the volume control on my speakers not work?

Answer: Your speakers require either an external power supply or batteries to power the amplifier, which is what implements the volume control. Make sure that you have fresh batteries or the appropriate power supply and that the power switch is turned on.

Question 3: Why does the red light on my speakers not turn on when I turn on the power switch?

Answer: Verify that you have fresh batteries or that you’re using a power supply for the speakers and that it’s powered on. If the speakers plug in, make sure there’s power at the wall outlet.

Question 4: Can I use any speakers with any subwoofer?

Answer: Not necessarily, because some speaker/subwoofer combinations have nonstandard connections. What you can do, though, is to cable the speakers as if there are two independent sets of speakers (the speakers themselves and the subwoofer).

You do that by connecting a ‘Y’ adapter to your sound card. Plug the tail of the Y into the computer and speakers into the branches. (Alternatively, some subwoofers work when plugged into the line-out jack on the sound card, eliminating the need to split the speaker-out jack connection.)

Question 5: I need to set up my computer for videoconferencing, but the noise is too distracting to my office mates. What can I do?

Answer: The best answer is the same solution as for noisy speakerphones — get a headset. You can get headsets that plug into your sound card speaker and microphone jacks directly, giving you good sound quality, keeping background noise out of your conversation, and keeping peace in your office.

Everybody Ought to Know About Computer Memory Upgrade

I would say that memory upgrade is one of the simplest and most cost-effective ways to speed up your computer , as much as it sound complicated to replace a computer memory, it is not!

What should we know about computer memories?
There are two kinds of memory in a computer –
1. Hard disk – which used for all kinds of storage such as words document photos, videos and so on.
Usually comes in variety of size – 80GB, 160GB …
2. Internal memory called RAM (Random Access Memory) – used by the central processor unit (CPU). When you open an application, the CPU loads this software to his memory (RAM) and uses it as a temporary memory to run the current application.

The main differences between these two memories are:
1. Hard disk has much more memory capacity.
Could be 80GB compared to RAM with 512MB (0.5G).
2. The CPU works much faster with the RAM compared to the hard disc.
3. Computer turns off empty the RAM contents, while the hard disc contents remained as is.

Why is it so impotent to have enough memory in your computer?
As I mentioned before, each time you open an application such as editors, video player or graphic application.
These applications are loaded into the internal memory (RAM) and run from there. The more applications you use at the same time this memory gets filled up.

Your computer start to slow down when there is not enough room for this application in the RAM and the CPU start to paging which means using the hard disc as his internal memory.
We already know that the hard disc is slower then the RAM and there you have it – a slow computer!

Do you need to upgrade our computer memory?
First of all you should check the size of the memory, an easy way to do that is to open the task manager.
CTRL+ALT+DEL, open the performance TAB, and then check the physical memory – total TAB – is the size of the memory.

Another thing that needs to be checked is the available memory size which should be in a regular operation at list 20 percent out of the total memory. Less then 20 percent will significantly slow down your commuter.

Things You Should Know About Computer

Computers are now being used everywhere. A computer that stops working altogether or executes tasks at a very slow speed is a serious problem for people who are dependent on it. Even if you are not very tech savvy, you can learn a few things about computer repair tools to fix most of the problems by yourself. It will also reduce the chances of paying extra money for repairing services that you could handle yourself.

1. A computer repair tool can be divided into two categories namely hardware and software. Cable cutters, screw drivers and canned air are some of the hardware tools used for computer repair. Anti-virus scanners, memory diagnostic utilities and password recovery software are common examples of software repair tools.

2. Canned air can be used to get rid of dust on the surfaces of mechanical components inside the computer cabinet. Multi-meters can be used to cross check Ethernet connections and power cables to detect possible flaws. An antivirus will help you to keep away viruses, Trojans and other malicious programs that can affect the overall performance of your computer. A memory diagnostic tool can help you find the problems with RAM.

3. Computer repair tools of both types offer various features and capabilities to diagnose and repair a fault. You need special screw drivers to work with small sized components in your computer. Similarly, diagnostic software can detect most of the hardware and logical problems with your devices.

4. Use an anti-static wrist strap whenever you open your computer for repair. Static electricity can damage some parts on your computer’s motherboard. Instead of treating your computer later on, install a firewall, update your antivirus and use latest BIOS software to prevent the problems.

5. Completely unplug your computer when you open the CPU cabinet to fix some problems. Take a backup of all important data before you begin to wipe out viruses from your computer with an additional software repair tool.
