why the computer performance is very slow

Problems on the computer often makes the computer users feel worried and anxious when they use computers have problems, so the computer can not support the performance of any work performed. if you are not a computer technician, please look at the following tips: 
First:the software (in terms of program), a slow computer is often caused by:

1. virus infections are a growing number of the files in the computer, including operating system files.
2. conditions of the operating system (Main Program computer system) is not as new when installed, there may be a corrupted file, a crash program for the installation of an application is less than perfect which ultimately led to timubulnya Badsector (some damage to hard drive capacity

suggestions for slow computers caused some of the above:

1. clean the virus with anti virus updates, then do repair the operating system, but in this case if the eradication of the virus is deficient or there is still left, the computer will return again slow due to the remnants of the virus will develop
2. for second point ,Do format the partition where the operating system and applications in pairs, in other words do the reinstallation, Bad sector aim to reduce the effects of the existing hard drive.

second:in Hardware:

1. RAM capacity is less wide, these conditions will be felt when we run many programs simultaneously, so that temporary storage media can not accommodate the entire program
2. Old age is hard drives (over a period of usage), or the amount of the damaged hard drive sectors. This causes the computer was slow when we run a program even started when the computer is turned
3. CDRoom unfavorable conditions, most problems come from the head CD-Room, the computer will seem slow even to not react when we insert a CD into the CD-Room

suggestions for computer slow because of the Hardware:

1. Add RAM to RAM used to be bigger, or do the settings on the virtual memory to take some hard drive capacity and function as a RAM (if Disk Capacity on Drive C: is still a lot)
2. store all data on other media, format it again on all the partitions so that when installing the operating system, the operating system can sort out / ignore bad sectors as a storage (hard drive is damaged sector will not be automatically used by the operating system)
3. avoid the use of  Damaged CD, because it can force the Head-Room CD to work very hard, it often blows head on the CD-Room

Finish tip, this Note is dedicated to those who really need, apologize to all of you who feel a Masters in Computer World.
