UPS Power Supplies To Protect Your Computer
Many people do not realize the absolute importance of purchasing a UPS power supply for their system. UPS stands for Uninterruptible Power Supply, but it is not uncommon to hear people refer to them as UPS power supplies, despite the redundancy. It can also be confusing to newcomers because there is also a "power supply" inside your PC - but that is a device that converts A/C power into D/C power and is often measured in watts of power supplied. A UPS is often called power protection - although it really protects your computer system.
Buying only a cheap power strip from your local retail outlet can be a huge mistake that could cost you thousands of dollars. It is worth spending at least $50 or more to protect your investment.
Each UPS first protects against electrical surges, spikes, and sags - the three S's of death to electronic components. Not only could your motherboard be damaged by any of these three, so could your monitor, your speakers, microphones, printers, and any other powered accessories. A quality UPS will generally offer a guarantee against these types of damages. You'll find these on power supplies by APC, Opti-UPS, and TrippLite.
Second, the UPS provides a source of pure energy even if the power goes completely out. While a power outage alone won't typically damage a computer, it is generally very inconvenient. Today's computers take up to three minutes to fully reboot, and if you were in the middle of something, it can take nearly ten minutes to be back at full productive status - all because of a 2 second power drop. For the workplace, the savings in employee productivity alone make this second feature invaluable.
An uninterruptible power supply works by filtering the electrical power coming from electric company while storing a small amount in a battery. The more money you spend on an UPS, the more battery life you buy. For a standalone desktop system with one printer, you'll want to buy a UPS that can give you at least ten minutes to shut down properly and save your work if they power doesn't come back on within a minute. Larger systems with bigger power supplies or dual monitors will want to consider models with even larger batteries. If you have frequent power outages in your area, you'll also want to think about a UPS with a larger battery.
One of the more recent features in the UPS market is the addition of USB connectivity. By attaching your UPS to your computer via a standard USB cable, your computer will give you reports of activity on the power supply. You'll be surprised to see how many times your UPS system protects your computer from harmful power spikes and surges. You'll be especially grateful for the number of times the power drops for a few seconds and you are able to continue working on your task, saving time, and often, important data that you might not have saved yet.
So, before you buy a bigger monitor, or that second hard drive, consider purchasing a UPS system first and protect your computer, your data, and your time.

Secure Your Computer From Viruses And Spyware For Free
One of the hazards of using a computer online today is the danger of infestation with a variety of malware, viruses, trojan horses, spyware, zombieware, worms, loggers, dialers - no matter what you're infected with, it carries the dangers of:
- Reduced performance
- Unwanted emailing
- Damage to your data, or even to your bios (which means your computer is toast)
- Theft of your data, up to and including all your personal information
When malware is released in a large network, the results can be even worse, with mass infections causing shutdowns of entire systems, theft of corporate data, and revenue loss that can rise into the millions.
Fortunately, a few free programs and sensible use of your computer can prevent these nasty things from happening to your computer.
Virus Protection
Install a decent virus protection software. You can download AVG Anti-Virus Free edition which is free for personal use, and ensure it's constantly updated.
AVG is easy to use, takes very few system resources, provides rapid virus database updates, and other great features like Automatic updates, E-mail Scanner etc.
And has excellent technical help available which other free antivirus software's lack.
Firewall Protection
If your OS is Windows XP, a default firewall comes with it, but you may be better off downloading another free firewall and using it since the Windows firewall has been shown to have some of the same security holes as IE and Windows. That doesn't mean the Windows firewall is bad, it just means that using software developed by different teams of developers will protect you better.
ZoneAlarm is a great free software for home users. It has got all the features a home user needs. Has simple interface, is easy to use and customize, works with little or no configuration.
Spyware Protection
You should also keep good anti-spyware software on your computer. Spybot - Search and Destroy is one of many good examples of these, and it's free. Be wary of anti-spyware programs that advertise via pop-ups; these "anti-spyware" programs sometimes contain some of the same problems they supposedly protect you from!
Spybot S&D is one of the best free Anti-Spyware software, I have been using it for last couple of years. Spybot is great at keeping spyware out of the systems. The program has an easy to use interface, very user friendly system. The program takes out cookies, spyware, ads, and many other things you do not want it.
Apart from Spyware removal Spybot has other Advanced tools like:
- Secure Shredder ? Securely remove files you no longer want from your hard disk.
- BHOs ? Show and manage the Browser Helper Objects from your Internet Explorer
- IE tweaks ? Modify some hidden Internet Explorer settings.
- Hosts File ? Take a look at your hosts list.
- System Internals ? Search for registry inconsistencies
- System Startup ? Show and manage the applications that your machine will run on System Startup.
- Uninstall info ? Show all registered software uninstall entries
Sensible Personal Precautions
Most viruses come from your email. This cannot be overemphasized. Never open an email attachment that you weren't expecting; always check with the person who emailed it to you, through a phone call or just via email or chat, to make certain it is a real attachment that's safe to open.
Other viruses come from illegal and legal downloads. If you're downloading illegal software or data, you can expect to find viruses in a pretty high percentage of it. What's tragic is that a lot of illegal viruses creep into legal download sites. This is why you need to maintain your virus protection program in an up-to-date manner, even when you're careful about downloads.
A few viruses are attached to web pages. Though their servers generally shut them down as soon as they're found, or your server blocks the sites to protect you, you'll find a few viruses that download to your computer simply by visiting a site. You can protect yourself by maintaining the Internet Explorer security settings at a medium level or higher, or by using alternate browsers like Firefox with good security.
Spyware often comes from "free" programs. You've seen those cool screen-savers for free? Spyware. Try to download free programs from places that vet their software carefully.
With these three software's (available for download at syschat.com) installed and some personal precautions your computer should be spyware and virus free.

Summer Sizzle Brings Blackouts, Sags and Spikes to Your Computer Systems
Why tempt fate?
Summer weather can not only zap your newer computer systems but also your vintage computer as well as non replaceable vintage computer software as well as the time and energy spent in setup, hardware replacement and running computer systems.
Why does the summer season bring so much trouble ? brownouts, sags and electric currents spikes?
Summer heat does wonders. Not only does it allow you to acquire a lovely tan but if causes utility grids to be strained beyond their capacity due to the increased use of air conditioners. In such cases power utilities adjust their voltage output, sometimes causing erratic power sags and spikes, which are extremely dangerous for computer hardware as well as software. And you can expect utilities to be more conservative to avoid another outage like that which happened in the hot August summer of 2003.
On Aug 14, 2003 it was estimated that due to a summer electric heat surge 50 million people and businesses were plunged into the dark and heat.
The summary cost was an estimated $ 6 billion.
Similarly it is estimated that in the United States that smaller outages cost the U.S. economy in lost productivity the not unsubstantial cost of $ 50 billion.
So says the IEEE ? the Institute of Electronics and Electronics Engineers. The worlds? leading professional organization for the advancement of technology.
Secondly the unique geography of the U.S. produces favorable conditions for tornadoes, resulting in about 1000 tornadoes every year according to the weather channel.
Tornadoes are highly unpredictable with wind speeds reaching 300 mph, a tornado is the most destructive storm of all, ripping up utility lines and leading to lengthy, unexpected blackouts.
As well last years hurricane season was a record breaker with more than an alphabet?s worth of named storms, causing the National Hurricane Center to resort to the Greek Alphabet ever. It was also the first season since 1851 to have three categories of five storms. (Katrina, Rita, Wilma).
Lightning is always the most obvious concern of most computer enthusiasts. Each lightening flash typically contains about 1 billion volts and between 10 and 20 thousand amps of current. Currents can transfer through wiring or plumbing and destroy everything in its path, of course including your irreplaceable Computer and Software Collection.
This damage is entirely possible. The National Oceanic and Atmospheric Administration (NOAAA) reports an average of 20 million cloud to ground flashes have been detected every year since 1989.
How can you protect yourself?
First of all purchase proper surge protection and have it in place.
There are various levels of surge protection devices.
1) Power bars with a simple switch. These are the choice of most as they are readily available and inexpensive. However the switch is just that a switch not a surge protector. The appearance of an electronic device fools many into believing that they ?are protected?. Sadly they are not.
2) Inexpensive Surge Protection devices. This is a better step than the first. However the protection is limited by the fact that the surge protection is afforded by simple Silica sand. With time and moisture (usually no more than a year) the surge protection is highly diminished.
If you use these inexpensive Silica sand based surge protectors replace them on a yearly basis. As well note the capacity of the surge protector. It does no good to have a very inadequate surge protector.
Read the labels and descriptions on the packages.
You can not protect a large computer system with a surge protector designed for one simple computer or laptop.
3) More expensive electronic surge protection units. A wise choice. However as noted above ensure that your protection is well rated above PEAK power use not a lower power use
4) Lastly you may well consider a more expensive though very safe solution an Uninterrupted Power Supply.
An uninterrupted power supply, or UPS, (sometimes called an uninterrupted power source ') is a device which maintains a continuous supply of electric power to connected equipment by supplying power from a battery when utility power is not available. A UPS is inserted between the source of power (typically commercial utility power) and the load which is to be protected. When a power failure or abnormality occurs, the UPS will effectively switch from utility power to battery power .While they are not limited to any particular type of equipment, they are typically used to protect computers.
Remember why tempt fate when it comes to your prized vintage computer system .
Fire departments not only fight fires they are most effective in preventing fires.
Remember at the very worst you can always unplug your computer and devices is to be safe . And as well remember to unplug the phone or broadband cable connection as well.
