Is your PC slowing down? Or maybe it crashing more and more, Well if that’s the case it just might because your PC is suffering old age! Yes that’s right just like people PCs suffer from the aging process too.

But there’s good news

But unlike people you can actually turn back the aging process and bring your beloved PC back to life. All it takes is a couple of easy to follow tips to ignite your PC’s performance to full speed again.

Just follow these easy to follow steps:

System configuration utility
Even when your computer’s sat there doing nothing it could be running at least 50 programs! These are programs that a munching away at your poor old CPU and not to mention having a right good go at your memory as well. The reason for this is because over time the more stuff you install the more crap that builds up and even if you don’t even use that program, there’s a damn good chance that it’s running in the background.

To see what I mean hit CTRL +ALT + DELETE then press the processes tab. It will show you how many processes that are running in the background.

1. To solve this little dilemma just go the Start or Run for XP owners, and type MSCONFIG.

2. The System configuration will appear and from in there go to the STARTUP tab.

3. Once you’ve selected the STARTUP tab you’ll be presented all the programs that are running in the background of your PC. What I would recommend is turning everything off apart from your anti virus.

If you do see anything what you do want on for example MSN massager by all means keep it on but the more you have running in the background the more it’ll sap your PC’s performance and will also affect you’re your Boot times as well.

System configuration utility part 2
Now still hanging around in the System Configuration Utility, go to the second tab called SERVICES and go to and untick the HIDE ALL MICROSOFT SERVICES. We’ve got to do this (unless you’re a bit more experienced) because if you go and turn one of Microsoft’s services you could just mess your entire PC up and we don’t want that do we.

Once you’ve unticked the box you should be just left with all the non Microsoft services.

once again I would recommend to turn them all off but the anti viruses services. Once you’ve decided what and what not gets the chop click apply and you’re done.

Performance Options
Depending on which OS (operating system) your using, this could make or brake it. If your using Windows Vista? I would recommend turning some the visual effects of especially on the lower end systems. However if your using XP, the performance will be less impressive but I believe every ounce of performance is crucial. Besides, you won’t even notice half of these switched of anyway.

Now as much as I would love to tell you how to get to these options, the ways to get there are very different when compared to Vista and XP. So a way around this (and probably a cop out as well) I’ll just tell the vista owners to type in PERFORMANCE into the search bar, select PERFORMANCE INFORMATION AND TOOLS and click ADJUST VISUAL EFFECTS and you’ll find your way there.

For XP owners read on:

1. Go to Start, Control Panel and select PERFORMANCE AND MAINTENANCE.

2. Then ADJUST VISUAL EFFECTS you should find yourself there.

Now I would recommend turning them all off barring the last one. The last one keeps the modern Windows feel which I personally like but hay, everyone’s different.

Uninstalling
A fast Hardrive is a empty hardrive. So if you’ve got an hardrive full to the brim, delete the programs and games you don’t need to speed up your Hardrive and watch those boot times fly!

Tip: If you’re a gamer (like me) What you can do is save the save game file and uninstall the full game. This way you can get the wanted gigs of space back but not lose your place on Crysis. Cool eh.

Defragging
Now there’s hundreds of other tips I wanted to share with you but I wanted to keep this article as short as possible to prevent you been bord to death. but the ver last thing I would do to my PC once I finish optimizing it is to defrag it.

Now your probably thinking that yes I already know that James. But what I would recommend doing is using a different defragger especially if your using the dreaded Vista defragged.

Now as you’ve probably gathered, I can’t stand Vista’s defragger, I think it’s actually a step backwards, not a step forward. But what really annoys me about it is that you have no idea how long it will takes and how defragmented your hardrive is.

But don’t worry, because I’m going to show you to download a much better one that Vista’s own shoddy attempt. Auslogics Disk defragger is its name and I think you’ll find it quick and easy to use and it seems to do quite a good job as well.

And another thing.. It’s completely free to download as well. Just Google “Auslogics Disk defragger” and you should find it in no time.

We all know the effects of data loss –but exactly what is it?

Data loss – A crash in computing is a condition where a program (either an application or part of the operating system) stops performing its expected function and also stops responding to other parts of the system. Often the offending program may simply appear to freeze. If this program is a critical part of the operating system kernel the entire computer may crash (a system crash).

Having noted the definitions for data loss I’ll note a few reasons why it occurs, and how to recover the data, as well as a few links to specialized sites.

1. User error – A simple mistake on behalf of an employee could lead to the loss of megabytes of critical company data. From the deletion of a critical file to the accidental deletion of database records, your customers could face large expenses and significant down time recovering the disaster created by a simple mistake.

2. Employee theft – Employees need access to sensitive data in order to perform their jobs. Your customers have to limit the information to which employees have access, ensure that terminated employees no longer have access to sensitive data, and be able to track who’s touching what, when and how.

3. Disaster – What natural disasters or unfortunate accidents might affect business? Magazines daily contain news of organizations that have faced unbelievable catastrophes. In the event that your or your customers’ organizations are hit with a fire, flood or other disaster, how will the data be protected?

One way is to have backups. Using an Iomega REV drive powered by Iomega Automatic Backup Pro software, configure a full backup to REV 35GB disks once a week. Once this backup is done, you can secure the full backup offsite. With your data now backed up in two locations, no single event will be able to damage both sets of data. This backup can be done through backing software, like Argentum™ Backup , which automatically detects and locates the proper paths, folders and files under any Microsoft Windows (95, 98, ME, NT, 2000, XP and 2003) platform. Argentum Backup does it for sure, without any mistake or occasion. Argentum Backup is designed to be suitable for both beginners and advanced users

But, the best and newest way are the online backup solutions, which help you protect your data on a regular basis (daily, weekly or monthly). One of this sites is Iomega iStorage, from one of the best backup companies. This site offers a feature-rich, highly secure online storage vault designed perfectly to meet the needs of small and medium-sized businesses. Includes administrative abilities that give you control of content shared and accessed. It creates multiple logins to the same account, giving members their own login and storage space and creates logins for guests to use with restricted access

Another site is www.backup.com, where you can find another on-line backup system, called @backup. It’s main features are:

·simple finding and selecting of files is made easy with our right mouse click options or with our explorer-like interface;

·You don’t have to remember to do a backup. @Backup remembers for you. You set your backup schedule and we do the rest;

·They encrypt your data with bank level security procedures before transferring over the Internet to our data centers. Your data is stored encrypted and only accessible with your password.

·You can restore files anytime. In the event of a crash, a virus infection, or a simple user error your backups are a click away. Additionally you have access to your files from any PC anywhere.

These are just two of the sites that offer you on-line backup system. The internet is packed with offers that vary from the size of the backup they provide to the monthly cost of the service. For your help, I’ve included a few links, to other sites, where you can find details and prices for on-line backups.

Don’t wait until it’s too late – make a back up plan now!

To pass the CCNA exam and earn this important certification, you’ve got to know switching inside and out. While you’re learning all the basic switching theory, make sure to spend some time with the one of three switching modes Cisco routers can use.

Store-and-Forward is exactly what it sounds like. The entire frame will be stored before it is forwarded. This mode allows for the greatest amount of error checking, since a CRC (Cyclical Redundancy Check) is run against the frame before it is forwarded. If the frame contains an error, it is discarded. If there’s no problem with the frame, the frame is then forwarded to its proper destination.

While store-and-forward does perform error checking, the delay in processing the frame while this error check is run results in higher latency than the other modes you’re about to read about. The latency time can also vary, since not all frames are the same size.

Cut-through switching copies only the destination MAC address into its memory before beginning to forward the frame. Since the frame is being forwarded as soon as the destination MAC is read, there is less latency than store-and-forward. The drawback is that there is no error checking.

There is a middle ground, fragment-free switching. Only part of the frame is copied to memory before it is forwarded, but it’s the first 64 bytes of the frame, not just the destination MAC. (Why? Because if there is a problem with the frame, it’s most likely in the first 64 bytes.) There is a little more error checking than cut-through, but not as much latency as with store-and-forward.

Note that the latency of both cut-through and fragment-free is fixed; these modes always look at the first six or 64 bytes, respectively. Store-and-forward’s latency depends on the size of the frame.
Learning the similarities and differences between these modes is an often-overlooked part of CCNA studies. Spend some time studying this important CCNA topic – you’ll be glad you did!
