The first thing you can do is clean out your hard drive. Go through and organize your files, music, media, movies, etc… Just like you clean your office and clutter can make you less efficient. Organize your files and deleting the ones you no longer need can free up dome extra space. For the big files mostly media, store them on a separate CD which can save you lots of space. Then after you organize your files you need to defrag your hard drive. This can be done through the Start Menu >> Accessories >> System tools. Then from there pick disk Defragmenter. Defragging your hard drive will organize your files that are written and group them together to make it easy for your PC to find and use it. Second you should run weekly spyware and virus scans. Spyware can wreak havoc on your internet speed and viruses can literally disable your computer. Spyware is mostly put on your computer without you even knowing it. When you visit certain websites they will put what is called a ‘cookie’ on your computer to track what kind of sites you visit and to gather statistics. Every time you close out internet explorer you can delete the cookies and temporary files. This will definitely give you more speed when surfing the internet. There are a handful of free programs to sort out spyware as well as anti-virus programs to guard your PC from any attacks. Last, but not least you should periodically clean your registry. Your windows registry is the command center of your computer and everything that runs, first passes through here. A corrupt and bloated registry will make a fast computer a slow one. It can also accumulate corrupt entries and invalid ones. This is often caused by installing programs and uninstalling them. Every time you do this is marks an entry on the registry and then deletes it. Manually trying to clean your registry can be slightly tricky and it is recommended you invest in a good registry cleaner.

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.
