Computer Tips

Computer errors are very common and every computer user may face different kinds of issues so they should learn about the solutions of the common computer related problems. The common factors that cause problems in computer are viruses, spyware, Trojan horses, adware, corrupted registry, faulty hardware, low memory, low capacity hard disk, low CPU speed and stuffing computers with large number of software applications. In this article, I have compiled a list of the most common computer problems and their solutions.

Computer is very slow

This is very common issue and it arises due to the several factors such as too many programs running at the startup, low RAM, low processor speed, spyware running as a background application, errors in the Windows registry and the buildup of the garbage files on the hard disk. Scanning your computer with an up-to-dated anti virus and anti spyware program, cleaning and repairing Windows registry, increasing memory, deleting temporary files, deselecting the programs at startup and uninstalling unwanted software applications can solve this problem to a very large extent.

Network Server is not accessible

In a networked environment every computer depends on the server for logon authentication, files access, internet and printing access and sharing server resources. The downtime and the communication failure with the server are very problematic and frustrating for the users. Check both end of the network cable and make sure that the attached RJ-45 connectors are properly plugged into the LAN card and hub/switch. Ping the server’s IP and make sure you get the reply from server. Ensure that your server is on and working fine. A large number of the running applications on the server and simultaneous access to the server from a number of users can slow down the performance and speed of the server. Scan your PC with an up-to-dated antivirus program because certain viruses and spyware are responsible for the communication failure. Replace your LAN card with new one and assign different IP address and try to connect with the server.

Computer locks up or freezes

Missing .dll files, viruses, faulty registry, defective RAM and spyware slows down the performance of the server and it locks up frequently. Scanning PC with the anti virus and anti spyware program, cleaning and repairing registry and increasing RAM can solve this issue.

Computer won’t boot

Faulty power cable, power extension and power supply all contributes to this problem. Checking one by one each of the above components can pinpoint the problematic part. Simply replace that part with new one and your compute is okay.

Computer reboots itself

Defective cooling fan, power supply, RAM, viruses and spyware can cause this to happen.

Memory usage is maximum in computer

Either the memory is less than the recommend memory to run certain applications, swap memory chips with each other, scan your computer for viruses and spyware, increasing the page file and physical memory can overcome this problem.

Browser’s home page has changed itself

This is most likely a spyware problem and scanning computer with an up-to-dated anti spyware program can fix this issue.

Computer’s clock losing time

If you see that your computer’s clock is losing time frequently replace your CMOS battery.

My computer can’t get connected to internet

Check IP address, gateway address, scan your PC for viruses and spyware, check network cables and make sure that server’s or gateway’s firewall application is not blocking http requests from your PC.

Computer making noises

Faulty RAM, VGA, hard disk, Sound card, Processor and other components produce noises. Make sure that each hardware device is properly connected inside the PC and if the problem is still not resolved then replace the faulty hardware component with new one.

It’s Now All About Computing Business Profitability

Everyone would like to work from home. But traditionally it’s a lot of inventory shipped to your home, most of which you don’t need, and then they put you on “auto-reorder” every month so that you keep “qualified”. And then it’s hound your friends, who will soon no longer be your friends, and bring them to the “hotel meetings”. This is where up to 500 people congregate to “learn all about it”. Then it’s the speeches and testimonials and the products and finally the “tipping point” that make the products so “valid” in today’s world. Sound familiar? Well I hated it. I wanted the independence of a home based business, but as I soon discovered it was anything but “home based”, as I found myself delivering products to peoples homes, not to mention the living room gatherings…ugh.

So, what’s the alternative? In today’s world, especially in the last few years it’s all about web site management and marketing. That’s right, now with the internet you never have to hound your friends again. You get a domain site, and learn how to “drive traffic” to the site. Get involved with a company that does all of the selling and telling for you. That’s right today it’s all on videos and audio downloads that are all at your fingertips, not at the hotel.

Is there a learning curve? Sure, especially for the not so computer literate, like me. But if I can do it so can you. It’s all about computing business profitability. Getting the public to view your domain, which then gets them to view your business opportunity. Once there the seminars that you used to take people to the hotel for are all online and they are now called “webinars”. You can view them live online and get some serious gifts just for viewing. Or you can watch a pre-recorded one which also answers most of your questions and answers. With the live one of course you can ask your own questions directly to the president of the company.

What You Need To Know About Computer

It is crucial that you clean all parts, corners and surfaces of your house. There’s no such thing as over cleaning. Never underestimate the power of a clean house. It can influence the health of the family. When we clean, we always take care of the things that are visible and functional. For example, floors, counter-tops, toilets, carpets, etc. Sometimes, we ignore other things because we think they are harmless for example, mattresses, windows, PC’s, etc. We think that they are not too dusty because they are less exposed but that is where we are wrong. Every computer accumulates dust, grime and germs that we need to tackle.

When you think about computer cleaning, you have two options here – do it personally or hire somebody else to do it for you.

Aside from keyboards, you have to wipe the monitor or screen and more importantly, you have to secure the CPU. Each computer has a fan that regulates the temperature. If there is any build-up of dust and dirt in one of the fans it can reduce the performance and to some point, it can destroy the system. It is best to consider professional help because you are dealing with specific technology.

Computer Tips If Your System is Running Low

In today’s modern technology, computer software requires enormous amounts of system resources and RAM. Microsoft Windows does its best to utilize what memory you already have installed, however, in many instances that is just not enough to properly operate many programs. Windows will use something which is called Virtual Memory, which basically is just some allotted space that the computer will use when you do not have enough memory (RAM). If you are multi-tasking you might actually end up encountering an error that will say “Your system is low on virtual memory”. This article will explain a bit about that, and give you some related computer tips on how to fix this error.

If you happen to noticed that your computer is running sluggish, it could be that your system is low on virtual memory, and you may have to increase it. To do this, you first need to know some information about your computer and operating system. Windows typically allocates a certain amount of this memory by calculating how much actual RAM you have. It will then create the page file to use with this calculation, it must also take into account how much memory the operating system will need, different versions of Windows use different amounts.

Another simple solution is to clean your hard drive up a bit as Windows will automatically try to use bits of it to create virtual RAM. Windows software can not actually differentiate between what is the actual RAM based memory and what is the Windows created “virtual memory”. If you have enough space on your main drive, then this could easily resolve the error. Before you change the settings via your control panel, you should run disk defragmentation. In the event that the virtual memory will be placed on your hard-drive, it will work more efficiently if the bits are contiguous and not fragmented all over.

Steps on how to change your virtual memory settings are as follows:

1. On your desktop right mouse click on “My Computer” the go to “properties”.

2. Click the “advanced” tab, and click the “settings” button in the performance section.

3. At “Performance Options” click “advanced” tab

4. Click the “change” button in the virtual memory section.

5. Select the option “system managed size”

6. Click on Apply or OK till back to desktop.

If these simple solutions do not work, another option which is quite effective and will get rid of the error message “your system is low on virtual memory” is to add more RAM to your computer system. These days RAM is quite inexpensive. Unfortunately, this is not always applicable because at times you already might be using the maximum amount of ram allowed on your motherboard.
