CMOS checksum error is caused when the CMOS values are incorrect or corrupted.
CMOS checksum error is caused when the CMOS values are incorrect or corrupted. This issue can occur because of:- Bad or old CMOS battery: Reboot the computer. If the error still occurs after rebooting, enter CMOS setup and check all values, this includes verifying that the time and date are correct. Once everything has been verified, make sure you save and exit the CMOS setup. If everything appears to be proper and the issue persists, try resetting the CMOS values to the defaults and/or Reset Configuration DataNote: If this issue continues to occur after you turn off your computer off it is possible that the CMOS battery may be weak or already used up. More details about replacing CMOS values can be found on your motherboard's manual- BIOS update:If you had recently updated your BIOS of the computer, the CMOS values could have been reset. Enter the CMOS setup and re-enter all the appropriate values. More details about entering the BIOS setup can be found on your motherboard's manual.If you are unable to enter into the BIOS setup or after running a BIOS update, your computer no longer keeps its values, it is possible that an incorrect BIOS update may have been installed for your computer or the version may be corrupted. We suggest you try to update the BIOS again or roll back to an earlier version. - Disconnecting power supply before properly shutting down the computer:If the power had been disconnected to the computer while running, it is possible that this could have corrupted the CMOS. Therefore, ensure that the computer is properly shut down before switching off the power supply. If you have a laptop, ensure that the battery is at least 25% charged before switching off the power supply. If the CMOS has become corrupted, enter the correct values in CMOS setup and save and exit the CMOS. This would surely solve your problem.

What is Search Engine Optimization - SEO?
Search Engine Optimization (SEO) is a website marketing scheme that enables a web site to appear in the top search results of search engines, whenever a user types a keyword related to the website. It has been found that generally web users take their results from the first two or three ages of search engine listings therefore it will be wise to have your web site ized for search engines in such a way that it appears in first 10-30 results, hat's the basic idea behind Search Engine Optimization i.e. SEO.
Search engine optimization (SEO) is termed as the process of improving the volume and quality of traffic to a web site from search engines via "natural" ("organic" or "algorithmic") search results for targeted keywords. Usually, the earlier a site is presented in the search results, or the higher it "ranks", the more searchers will visit that site. SEO can also target different kinds of search, including image search, local search, and industry-specific vertical search engines. This was just about organic search results but now paid listings - Pay per click (PPC) Ads have also become popular, paid listings are othing but a concept that allows you to display your ads by paying a certain ount of money to the online advertising company, a simple example of paid ings are the ad's coming at the right side of your search results window which can be identified as "Ads by google".
Paid listings (PPC) doesn't mean that your ad will appear every time on google whenever a user in any country types a keyword, but the ads will be displayed only when a relevant search has been performed and also it depends on what keyword details are cified by you in your advertising campaign. Search Engine Optimization (SEO) is a vast field and also very complicated as its based on the regularly nging search engine algorithms or search criteria. ptimizing a site for search engines involves vast research work along with patience. Simply editing meta-tags and submitting your web site to search engines doesn't complish anything, in fact the importance of meta tags has been reduced in the sent scenario due to the changing environment. The most ortant factor that a web site must posses is - targeted keyword rich content.
The power of content dominates over meta-tags and other minor criteria's. The keywords included in the content should be thoroughly researched. Your e for optimizing a website should be unique and constituting many different -aspects needed for making a website's appearance felt in the World Wide Web.Search engines (Google, Yahoo, MSN etc.) often base their rankings on relevance and definite rules/algorithms so if you obey the es/algorithms in the way your website is set up, your site can attain better rankings in search engine results pages.

What is RAMAuthor: Robert Thomson
operates much like a human being's short-term memory. Much like the human brain RAM is able to draw upon the computer's long term memory for information. This is often necessary when short term memory becomes full. Most computers come equipped with at least 256 million RAM bytes plus the hard disk which has the capability of holding 40 billion bytes.
Anyone who works as their own tech geek on their may be highly concerned about what is ram? It is a very important piece of a computer system. It is Random Access Memory which is the location where the application programs, the operating system, and data presently in use are stored. This way the computer's has the ability to reach them momentarily when needed. RAM is head and shoulders above the other various types of storage inside a computer system. It's even faster than floppy disk, hard disk, or CD-ROM. The information stored in RAM is only accessible for the length of time that a computer is begin run. Information previously stored in RAM disappears when a computer is shut down. When the computer is turned back on, information from hard disk is retrieved to bring RAM back to the forefront again. RAM is much like main memory that is accessible by programs.
How Does it Work?
RAM operates much like a human being's short-term memory. Much like the human brain RAM is able to draw upon the computer's long term memory for information. This is often necessary when short term memory becomes full. Most computers come equipped with at least 256 million RAM bytes plus the hard disk which has the capability of holding 40 billion bytes. Data is placed on a magnetized area that resembles a record. Computer printers also hold bytes of RAM as well. Each byte of RAM has the ability to be ascertained separately without the other bytes being accessed.
Types of RAM
RAM comes in dual forms. DRAM which is Dynamic Random Access Memory and SRAM which is Static Random Access Memory. DRAM is the most typical of the two types. DRAM requires refreshing at a rate reaching in the thousands each second. DRAM's times for accessing information are 60 nanoseconds. SRAM is more costly, but does operate at a much quicker pace than DRAM. The interlocking of a capacitor and a transistor produces a memory cell. This is one bit of data. Also, SRAM allows access at times as quick as 10 nanoseconds.

How to build a Computer
This is a complete step-by-step guide of buiding your own computer. We are giving you all the tips and hints that you need to know before you start building your own computer.
Step 1: component selection
The first and most important part of any computer system assembly is proper component selection, both compatibility- and performance-wise. Ensuring that the memory is compatible with the mainboard, videocard is of the proper interface and supports the necessary features, power supply is of adequate wattage and quality, enclosure having adequate ventilation is a must-do in order to have a trouble-free system which performs as expected. The best ways to make sure that all the candidates for your system are compatible with each other are:
Review websites: searching for a review of every part is a good idea, as the editors often indicate whether any issues were encountered. A good review will also give you a performance comparison to other similar parts, so you will know what to expect from your system.
Salesperson or customer service representative: since it is a part of their job description, a knowledgeable service rep will be able to offer a good advice or suggestion as well as prevent possible complications.
A knowledgeable friend or acquaintance: chances are high that either you know someone who is into computers or someone you know knows one. Beware of biased opinions though.
In the end, the more sources of information you use, the better the chances of you getting the right hardware.
Step 2: assembly
Now that you have all the parts, time to make them a whole.
Prepare for assembly: make sure you are not wearing synthetic clothes as they could cause an electrostatic discharge and damage the delicate electronics. Also ensure the space is well-lit since you may need to operate with really tiny parts like jumpers. When unpacking the parts, it is best to leave them in/on the electrostatic packaging they came in until installation.
Install the power supply into the case and bolt it down. If it is a modular type then also install the connectors corresponding to the number/type of devices in your system. Now would also be the best time to install the extra case fans, if you got any.
Line the mainboard up with the case (or removable mainboard tray, if your case has one). Screw/snap the standoffs into the case/tray ensuring that you have the same number of standoffs as the mainboard's holes. If you have one or two fewer, no big deal; if you install an extra one it will touch the mainboard from the backside and will either short-circuit it or prevent it from powering up. Small but important detail.
Install the CPU by opening the locking mechanism on the mainboard and carefully dropping it in (refer to your mainboards' manual). Do not ever use any force; if it doesn't fit it means you may need to rotate it. Install the heatsink by placing it on top of the CPU and either pushing the locking pins through the holes (Intel) or locking the lever (AMD). Refer to the manual if not sure. Next, install the RAM modules ensuring that you match the notches (RAM fits only one way), as well as placing the stick in dual-channel mode, if your system supports it.
Now that the CPU and RAM are installed in the board, time to place it inside the case. Before you do that, however, make sure that you place the IO shield (the metal plate with cutouts for mainboard connectors) in the case. Almost every shield is unique, so you must use the one that came with your mainboard. After that, place the board right over the standoffs and bolt it down. Plug the large 20 or 24-pin power connector as well as the smaller 4- or 8-pin 12V power connector into the board. Now connect the HDD activity LED/power/reset button connectors, referring to the manual for proper placement.
Install the optical and hard drives as well as floppy drives and/or card readers into the case. Connect each one to an appropriate data cable, such as SATA cable for hard drives and flat IDE cable for opticals. If you have more than one optical drive, you may need to set the jumpers at the back of the drives, with one drive becoming the master and the other - slave. Plug the corresponding power cables from the PSU into each device as well. Card readers do not require a power cable, and get both power and data through the USB cable connected to the mainboard. Again, refer to the manual for proper USB connection guide.
Install the graphics card and other devices such as sound card and TV tuner. Connect the 6-pinIf you have an SLI or Crossfire platform, connect the two cards with a bridge if required. Note: it is also a good practice to first install nothing but a single videocard into the freshly-built system, as it will prevent possible conflicts which older operating systems are prone to, and then add one component at a time.
Now that your system is assembled, check that every component has power running to it from the PSU: videocard should have one if it is a high-powered one, HDD's, floppy and opticals should have a data and power cable.
Connect a keyboard, a monitor and the power cable. Now hold your breath and push the power button on the system you have built with your own hands. Considering everything was done properly, it should emit a short beep and start booting. It will stop at the point where it detects that no operating system is present, saying something like: "Boot disk failure, insert a boot disk and press any key when ready". Read on to find out what's next!
Step 3: OS and drivers installation and testing
So you have a system that's successfully powered up and is humming along. But to make it useful, you need to be able to interface with it. In the future, humans will be able to hook directly into the system; today, we use different Operating Systems, with Windows XP or Vista being the most common ones and others like Linux being used in more sophisticated fields.
First, restart your computer by hitting Ctrl-Alt-Delete simultaneously. When it starts booting up again, press Delete again right after it beeped in order to go into the BIOS setup. BIOS stands for "Basic Input Output System", and it performs the most basic tasks such as detecting hard drives before an Operating System has been even installed. Navigate through the options to find one that is called "Boot priority" (refer to the mainboard's manual). Set one of the opticals as the first boot device, and the hard drive(s) as secondary ones. Put the Windows installation CD/DVD in the drive designated as the first boot device. Now hit F10 to save the settings and reboot. Note: if you have a card reader connected, it might be a good idea to disconnect it for time being; otherwise, the main hard drive may be designated not as C: on some mainboards. Always power down the computer and disconnect the power cable when connecting/disconnecting devices!
This time, the PC will find the Windows CD/DVD in the drive, and will start the interactive installation. All you need to do is answer simple questions such as Time zone, who will be the main user etc. Upon completion of the installation, the computer will finally boot to .
Now, you must be eager to start using your new system. However, there is the last step to be taken: driver installation. Drivers enable the OS to recognize and use the hardware such as graphics and audio cards, network adapters, and even the mainboard itself is not fully functional until the chipset drivers have been installed. All the drivers can be found on the bundled CD's that came with the hardware. You should install the mainboard drivers first (sometimes the manufacturer creates a program that does all the driver installation for you), then everything else. Remember to reboot every time you are prompted.
Finally, it would be a good idea to test out the new system, to make sure that all devices are functioning properly. To do that, you can either simply use the computer for whatever purpose you created it, or run specialized programs which quickly determine whether your system is fully stable and is able to cope with heavy loads. The most popular ones are the 3DMark series by Futuremark for graphics stability and performance measurement, HDtach for hard drive performance measurements, memtest86 for memory, Prime95 for overall chipset/CPU stability and S&M for extreme load simulation. The exact way to use each one is included in the program's manual as well as is available on many forums/discussion groups.
There you have it, a pile of parts turned into a complete computer system. Unfortunately, the above guide represents the best-case scenario, and the reality is such that quite often a problem may occur at any one of the above steps, and resolving or even listing every potential one is well beyond the scope of this article. The best way to resolve one is either asking for manufacturer's help, browsing the forums or maybe even taking the system to the shop to have a certified technician take a look. Either way, there are no miracles and every problem has a fully logical explanation and a way to resolve it.
