10 Reasons Why Your Computer Runs Slow There are motives for your reduced speed and any one of them could result in a crash and an up close and personal viewing of the BSOD, (Blue Screen of Death). A slowdown occurs over a period of time. Essentially, if you are on dial-up that is slow to begin with and if you have less than 512MB of RAM, that too can be a major cause. Here are 10 others:

1. Start up overload. As you add additional programs, they claim start-up status quickly and quietly. The more programs you have that are loading at start-up, the slower the start-up. Go to start, all programs, scroll to Startup and see how many programs are lurking there. The decision is yours. Remove the programs you do not want, or are not necessary, to be starting at boot-up.

2. Spyware: Malicious programs that stealthily embed themselves into your software. They are installed in your software, without your knowledge, in many ways. Through e-mail especially, the ones that are multi-forwarded. You know who sent it to you, but what about all of those other names? Who are they? Through free scans or free downloads. Through Web sites that you visit that specialize in this practice, and music downloads.

These must be removed from your computer before they cause damage to your operating system and applications and bring your system to a halt. Using your browser, go…. There you will find many anti-spyware programs. Ad-Aware SE, SpybotSearch and Destroy, and Spyware Terminator are three good ones. Run them frequently and keep them updated. 3. The Registry. If your registry is corrupted or bloated, there could be a BSOD in your future. The Windows registry is the master control center for your operating system and theapplications it runs. Corruption or overload can cause: performance problems, includingapplications at start-up, slow windows start-up, extremely slow shut-downs and a general disruption of system processing. Unless you are absolutely sure of what you are doing, DON'T manually attempt any changes to the registry. I go there frequently but not without first backing up and/or setting a restore point.

Once again,…. Noquotes can lead you to several good registry cleaners and optimizers. I have a couple of "freebies," but in this case, I recommend Registry Mechanic and use it after each session. One of the free ones is Ccleaner. It is safe since it has a back-up feature as does Eusing Registry Cleaner.

4. Badly Fragmented Hard Drive.Over time, your computer's files can be scattered over your hard drive; this is called fragmentation and a cause for file searches to be slower than usual. Use the built-in tool of Windows to solve this condition and be patient as it runs.

Single click "My Computer," right click "C" drive, click properties, click tools. Highlight your system drive,(usually C ) then click defragment. While you are there, on the General tab, you have the option to Clean the Hard Drive. Click disk cleanup select all the items in thewindow. Follow the instructions and OK your way out. This, along with the defrag, will put your hard drive back in proper working order. While you are there, uncheck the box for "indexing the files" this is another source of slow-up.

5. Poor Security Software. A large number of security programs, and suites, are bloated with software and demand a great deal of system resource and memory. The constantsurveillance of your system for malicious ITD's can cause your system to get sluggish. Yes, system security is essential, but some of the programs have gone overboard with coding and, some of the lesser known, can be a source of system infestation.

These programs we have previously recommended do not fit in this category. Sunbelt-Software's CounterSpy has been my favorite standby. It is not free, but it is user-favorable with an easily understood interface and more features than others I have tested.

6. Remnants of Uninstalled Programs.There is a program that I recommend, and use, for complete un-installation: Innovative Uninstaller Pro. The writer of this software is consumer-oriented and offers a free test period. In checking in the registry, I have found it does remove the coding and softwareof an uninstalled program you merely drop the icon of the one you want uninstalled on the uninstaller icon. Cool what? A good start on your way to a clean-up is through RegCure that cleans up previously left behind debris.

7. The Page File. The Windows Page File is a temporary source of memory used by the system in processing functions. It is actually a buffer that is used for "wiggling room." If your page file is too small, your operating system will not have enough room to move and the result will be poor performance and error messages.

If this is your experience, you can increase the size of the page file. Right click on MyComputer and go to "Properties," click "Advanced Tab," click "Settings" in the "Performance" section, click the "Advanced" button, click "Change" under "Virtual Memory" Microsoft recommends that the paging file be 1 ½ times greater than the amount of installed RAM. However, Windows can automatically adjust this for you. Select "System Managed Size" then click the Set button. OK your way out.

8. Too Many Windows and Temporary Files. Your hard drive could be crammed with many useless files left over from re-installs, and just general use. To clear these up, you can first refer back to item #4 and clean your hard drive or click on "Start" then "Run" then enter "cleanmgr.exe" without quotes. Select the "C" drive and click ok. The hard drive clean utility will pop-up and do its thing.

9. Viruses or any ITD. Is this the "tail-wagging-the-dog?" Could be! But by this time, you should be fully protected with a bi-directional Firewall, (theWindows Firewall is only One Way), a good reliable and up-to-date anti-virusprogram. Because no individual spyware program can get all of the ITD's, two is better, three recommended. AVG is a dependable anti-virus with a free capability, but then, go to… with no quotes, and do a little shopping.

10 Hardware Problems. There are assortments of things that can happen to your hardware: wear and tear, over heating and dust. If you do not know how to clean the inside of your machine, put "Dust Removal" in the subject line of your e-mail to me. If you do experience a failure, crash or a shut down it can be traced to a hardware problem. These are the 10 most prevalent reasons for your computer slowing down. They are not listed in any particular order or by their gravity;

It may be due to a virus or due to any problem involving the formatting of the computer.

Dear Ammas Member, There are several reasons for which a computer runs slow.The same are discussed below.Since you have not mentioned a particular OS, I am to mention it for Windows OS. Reason#1: If an effective and updated Antivirus is not installed in a system, there is possibility of virus effect.In this case virus consume substantial memory for pay load and captures EXPLORER process.In such cases computer is painfully slow.A good AV scan may solve the problem. Reason#2:Some memory hungry applications, if installed in a low-end PC makes the performance slow. So avoid installing big graphical applications like games,editors etc. or else install more memory modules (RAMs) Reason#3:If you are using multiple memory modules(RAMs) and one goes deffective, you may get slow performance.Some other hardware may also cause lowered speed. Reason#4: Due to passage of time your registry gets overloaded with unwanted software records/setting causing seek time to increase and thereby slows down the PC. A good registry cleaner can solve the problem. Reason#5: If your hard-disk has fragmented files due to improper shut-down of the PC for several times, it performs slow.Use of a good defragmatation tool may solve the issue. Some tweaks may speed up your system. Such as: setting location of pagefile, Disabling system restore etc. A good knowledge in system is needed for the same.

Reasons for slowdown of computers sometimes:

1. Numerous programmes running backend 2. too much of data on hard disk reducing the free space. The less the free space, the more are the chances of slowness. 3.installing and unistalling repeatedly number of programmes which might leave some of their residues on the system. 4. toomuch of data saved on the desktop. 5.if the Pc is full of viruses, adware, spyware or trojans

depending upon your work and your hardware ratio. It seems to be slow and fast in times. (example 1.when working with text editing program, the visual look like fantasy but hardware does not have any thing work. The speed depend upon your typing speed 2.when working with rendering program (acad , internet flv player , java virtual program other background database)here your interfece is less and you seems small window motion picture but hardware as to calculate your graphical output line by line)By this you seems to be slow and fast in times. Better way to maintain speed and make your work effiency remove all unwant visual effects fantasy program that occupies you system tray and other background function. Always stick with your work directly to your hardware

Computers can be slow sometimes for the following reasons :

1. Presence of Virus 2. Less RAM (which can be bought from the vendor and increased to solve the problem) 3. Hard disk too much filled and so computer is not able to function well. To prevent this, one should backup not so frequently used data in external harddisk and preferably delete it from the computer 4. If the computer is very old and software is a recent version, software is heavy for the machine and so it will slow the machine down.

Generally a slow computer is due to RAM issues. You can get the RAM upgraded and the problem will be solved very easily.

If you are browsing, the slow computer could be just slow internet connection. If this is the case, then you need to contact your internet service provider to solve the problem.
