Troubleshooting Computer Freeze (Lockup) Problems

February 11th, 2012

How familiar does the following sound? Your computer was working fine, but then suddenly started locking up (aka hanging or freezing), rebooting itself (crashing) or shutting down spontaneously? If you know only too well what I am talking about, then read on! Performing the simple steps below can fix the majority of lockup cases.

1. Check for recently installed software or hardware.

If the lockups started to happen after you installed a new peace of hardware, new software program, or new drivers, uninstall it and see if the problem goes away.

2. Run your antivirus program.

One of the first things to do in the case of sudden lockups is to run your antivirus program. Check your antivirus manufacturer’s website for updates and latest virus definition files. (This is absolutely necessary, outdated antivirus is not going to be of any use!) If you don’t have antivirus software installed – or if updates are unavailable – run one of the web-based antivirus scans that some major antivirus vendors like Trend Micro are offering for free. You can find a comprehensive list of available web-based scans and free antivirus programs on http://www.free-antivirus.info.

3. Run some good spyware removal tool.

If your machine is not infected with any viruses, it is still possible that it has some harmful adware or spyware is present. Download and run some good spyware removal tool such as AdAware or Microsoft AntiSpyware. Check http://www.free-antivirus.info for a list of free spyware removal applications.

4. Check for free hard drive space.

When no viruses are found, check out free hard drive space on drive C:. Make sure there is more than 20% of free space available; low disk space can lead to random lockups.

5. Check for overheating.

Overheating is another known cause of lockups. It can be caused by problems with fans inside the case, dust buildup, or other cooling problems. Make sure the power supply fan and CPU fan are running and free of dust buildup. You can check the temperatures inside the case by running Motherboard monitor

http://mbm.livewiredev.com

- make sure the temperatures are within the preset limits. Be very careful while cleaning inside the computer case (use plastic vacuum crevice tool) and NEVER OPEN THE POWER SUPPLY CASE as it contains high voltage.

6. Check the hard disk.

Check the hard disk – it is possible that its logical structure is corrupted. To check the disk for errors, right-click on the disk C: icon in “My Computer”, select the “Tools” tab, check all check boxes in the “Check disk options” field, and press the “Check now” button. It should ask whether you want to schedule the check next time you restart your computer – answer “Yes” and restart your PC. The check will be performed automatically after startup; it can take a while, so be patient. The program will attempt to fix some problems automatically – however, if the hard disk is failing physically, it will need to be replaced. It is also a good idea to run Disk Defragmenter (located in Start Menu > Programs > Accessories > System Tools) to optimize data placement on the hard disk for increased performance and reliability.

7. Check the memory.

Sometimes random lockups can be attributed to the computer memory (RAM) starting to fail. You can test the memory by running Windows Memory Diagnostic that can be downloaded from http://oca.microsoft.com/en/windiag.asp. If memory problems are found, try re-seating the RAM (pull it out and plug it back in). If it doesn’t work, replace the defective RAM.

8. Check for other hardware problems (advanced users).

More hardware-related problems can be diagnosed by running hardware tests from the Ultimate Boot CD that can be downloaded from http://www.ultimatebootcd.com. However, you should only use it if you know what are you doing – some programs on that CD can be dangerous when used inappropriately (for example, some of them can wipe the contents of your hard disk).

9. Update Windows and drivers.

Some lockups can be caused by outdated software components – update your windows and drives by running a windows update: http://windowsupdate.microsoft.com (it’s good idea to run it regularly).

The above steps will help diagnose and eliminate the most common causes of lockups. Hundreds more of other possible scenarios need to be dealt with on a case-by-case basis, as it all goes down to your particular computer configuration. Asking on PC

troubleshooting forums/newsgroups should help you figure out solutions to not-so-obvious lockup cases.

The Best Business Laptop For Your Company

February 5th, 2012

The little notebook computer or laptop is tailor made for business.

It’s the perfect communication tool. It’s the perfect record keeping

tool. It’s the perfect presentation tool. And if that wasn’t enough,

all of the above is neatly packaged into a small portable machine

that can be taken anywhere and everywhere.

For any size business, small to medium to jumbo, the notebook

computer is fast becoming an essential tool for business.

Savvy business people know acquiring the right tools is an important

factor in determining the success or profitability of any company.

Therefore, along with the regular outfitting of your company or

business – equal consideration should be given to choosing your

notebook computers.

Business owners should be aware that notebook technology is changing at

a blistering pace. Every two years or so, there is a whole new generation

of notebooks and notebook technology to consider. Notebooks are getting

smaller, faster, and better connected. They are also offering performance that

is matching or almost matching their desktop rivals.

Major reasons why, for the first time in history, notebook computers

are outselling their bigger cousins, desktop computers. Business

buying, no doubt, plays a significant role in all those sales. Large

corporate organizations are buying notebooks for their companies, sales

people and employees. It makes for a more competitive company in a very

competitive world.

But how do you pick a good business notebook computer? What’s the criteria

for judging a good machine? What’s the right laptop or notebook for your

company or sales staff?

Here are some important factors any business should consider when buying

a notebook computer or laptop for their company. General factors that

determine a good business notebook. Consider these…

Portability

Perhaps, the most significant factor and the main reason you’re buying

a notebook computer is portability. You can take it anywhere. You can

take your records, reports, presentations or products where ever they

need to be. For the business traveler or ‘road warrior’, the notebook

computer is an essential tool for their business.

When buying their notebook of choice, these ‘road warriors’ look

at the portability of their notebook. Size and weight are very

important. They want something that’s light and small, yet powerful

enough to do the job. They will probably look in the Ultra-Portable and

Thin and Light classes of notebooks to make their choice.

Notebooks in those categories are usually well under 5 pounds, around

10 by 14 inches in size and approximately an inch thick. Small enough

to throw in a briefcase or tuck comfortably under your arm. They won’t

drain your energy even if you have to lug it around all day!

Battery Life

You also have to look for a notebook computer that will last long

enough to get the job done. You want sufficient battery life for those

long plane trips. Fortunately, battery life is increasing, you can now get

up to 5 or more hours on high quality notebooks. Buy the highest

numbered cell battery, and buy any optional built-in battery extras

that will increase battery life.

Connectivity

You want something that’s easy to connect to the Internet

so connectivity is another important factor. Being in constant

contact with all your employees can be a determining factor in your

choice of notebooks. Communication is vital. Most high quality

notebooks come with Wi-Fi (Wireless Fidelity) connections,

many have a tri-mode 802.11a/b/g wireless system.

Some newer models, like the Sony’s New Ultra-Portable VAIO VGN-T350P,

are raising the bar, it has the world’s first ‘Built-in Cellular

Modem’. You can use your cell phone to connect to the Internet. This may

be a great advantage since finding a ‘Hot Spot’ in some parts of the world

can still be difficult.

Performance

You need to consider the performance level of your business computer.

Can it handle all your company’s demands, can it handle heavy graphics,

charts, diagrams, spreadsheets, etc. Check out the RAM — higher RAM will be

better for graphics and video. It’s generally agreed that you need at least

256MB for Windows XP and Mac OS X. You will only need 128MB for other

operating systems in Windows or Mac.

Most notebooks come with plenty of storage space, 60-80 GIG hard drives

are common. External drives are also available if you need extra

space.

Other tasks may be important to your line of business. For example, if

you need to take notes in the field, i.e. real estate agents, engineers,

doctors or medical personnel — then a slate or a convertible tablet

may be a better choice for your company.

Sturdiness

This is important if you want a notebook for a lot of road work or

business traveling. Your notebook should be sturdy or ruggerized to

be able to take a good pounding. Many notebooks have some novel

sturdiness features such as IBM’s Active Protection System which is

designed to protect the hard drive from falls and spills for those

accident prone notebook users in your company.

Security

Living in today’s world we need safeguards and security measures

in place to protect your company records and files. Not to

mention, to guard against the theft of your notebook computer itself.

Along those same lines your notebook computer should have advanced

security features. Many notebooks such as the IBM/Sonoma ThinkPad

series include an integrated fingerprint scanner for biometric

authentication that uses an Embedded Security Subsystem and Password

Manager.

Image/Style

At first glance this may seem like a superficial buying point, but

not really. In today’s business world, image or style does count and

contribute to your button line. Sad but true! You want a notebook

computer that matches the image of your company.

There is one to fit your needs, you have a whole range of styles

of notebooks to choose from, whether it be conservative black or

blazing race car red. Most businesses are ultra-conservative (nature

of the beast) and should pick a notebook along those conservative lines, other businesses may want to promote a sharper or cooler image

such as in fashion, creative arts, music industry…

Price

Economy or Deluxe. Similar to the style, another major buying

factor is price. You can go from inexpensive notebooks

to luxury models. It all depends on your company’s resources

and the image you want to project.

You can choose from the relatively inexpensive but very capable

DELL notebooks…all the way up to notebook manufacturers like the

UK based Rockdirect notebooks which offers upper end products that

can be custom made to your specs. You can even choose your own color!

Like any company purchase, especially if you’re buying in bulk,

getting a good special volume price may play a role in your choice

of notebook. Always check with these notebook companies for a

group or company order — you may be pleasantly surprised at the

savings.

However, don’t sacrifice performance for a special price, make sure

the notebook computer you’re buying has all the desired qualities:

portability, performance, battery life, connectivity, security and style,

– all the features you want in your company’s notebook computer.

If you consider all these factors, your next business notebook computer

purchase should just be a little bit easier.

There’s no reason why you can’t put this little modern workhorse to work

for your business or company. Used properly, the business laptop can

make for a well organized and cohesive work force that will pay big

dividends down the road, delivering a great return on your initial

investment.

The Best Lightweight Printers Available Online

February 2nd, 2012

Before we decide which one is the best lightweight printer online, let us first decide which printers online are lightweight. Since we want to know which printers online are lightweight, it will not hurt to consider checking which printers are the smallest printers. After all, weight can be associated with size.

Currently, the smallest printer available online is the PrintStik. There are 4 models available and the lightest is the first model known as the PrintStik 900. Its dimensions are 11″ x 1″ x 2″ (360cc) and it, weighs around 1.5 lbs. Aside from the size and the weight of this printer, let’s see what else it has to offer. In terms of quality, it can print up to 3 pages per minute and at a resolution of 200 x 200 dpi using thermal printing technology. It only uses USB interface unlike its later models, which have the additional Bluetooth connectivity.

Next to this is Brother’s mobile series, specifically the MW120. Its size is comparable to a size of a notebook at dimensions 6.3″ x 3.9″ x 0.7″ (281cc). This printer is actually smaller than the world’s smallest printer is. Weighing 0.69lbs, it is also lighter than the PrintStik. However, it is not able to print on large size papers. The maximum size it can print is an A7 (4.1″ x 2.9″) size. It has a higher resolution compared to PrintStik at 300dpi. This printer also uses thermal printing technology.

Now we go to the PrintBrush, which was developed by PrintDreams. This printer is certainly the smallest and the lightest with the volume of 200cc and a weight of approximately 0.55lbs. Its monochrome resolution is at 600dpi, which is 4 times higher than Brother’s is. It uses Bluetooth and infrared connectivity as well as USB. The printing method for this is different compared to the previous two. Instead of thermal printing, it uses inkjet technology. You print with it by waving it back and forth on a surface, as if you were brushing, hence the name PrintBrush. It is expected to be released in public on the 3rd quarter of 2010.

Unfortunately, light doesn’t always equate to quality. As you can see, we mentioned that all the resolutions they have are far inferior to the ones you would expect to have in a desktop printer. Neither one of them offers a print speed that is good enough and not one of them offers colored printing. So how do we decide which is best?

Now let’s take on another angle. If you wish to know, what the best printer is, which is also lightweight, then look for the best travel printer. Travel printers are already light since they were designed specifically for portability purposes.

The best lightweight printer doesn’t have to be the printer that you can fit in a pocket. The best lightweight printer doesn’t have to be the printer that weighs the least either. The best lightweight printer should be a printer that maintains all the qualities of a good printer and should at least be light. The best lightweight printer should be the best of travel printers.
