A computer with high RAM can run many programs at the same time with out any problem.
2. LOW PERFORMANCE OF PROCESSOR.
Processor is the brain of a computer, without processor nothing can run within a computer system.

3. COMPUTER VIRUS.
Virus are also the main reasons for a computer to run very slow, its proposed for the computer user to install very strong anti-virus and scan at least one day per week, also its proposed to update antivirus everyday. Anti-virus must be updates all time due to production of new and strong virus everyday.
4. DESTRUCTION OF HARD DISK.
Hard disk is used for storage of data in computer system. The kind of storage that hard disk perform is differ from RAM. RAM is used to store data temporary while hard disk is used to store data permanent. When computer shutdown no any data are lost in hard disk. A computer with bad RAM are usually run very slow.
5. MANY PROGRAM INSTALLATION.
