1. Computer shutdown safely on previous days don't showing display now. Particularly during damp season it is a common problem. Switch off the power button. Open the side cover of your CPU. It is easy. Remove two screws on the back of the CPU on the left side. Then push the side cover gently and remove it. In side the CPU find the slots of RAM. Push the white clips on the two ends apart of each RAM gently. Remove the RAM from its slot and clean the metallic (brass ) border with a brash or piece of cloth. And also clean the slot by a dry bash several times.Then place the RAM gently on the slot. Restart the CPU. CPU should be opened at least once a month to clean the dust regularly with blower or a soft paint brash. 2. Old keyboard may create problem: During starting, computer sounds with a short beep. During starting if computer sounds with a long beep or two or more short beep that is other than a short beep should be considered as something abnormality in the hardware. And your computer will work properly in this situation. The most provable cause is the old ( even new sometimes) keyboard, due to many causes particularly logging small insects or food particles under the keys causing abnormal command. How will you confirm it? Power off the computer, remove the keyboard and restart the CPU. If it works correctly replace the keyboard or one can also clean the old keyboard cautiously and then reuse it (better don't use it). 3. In a used computer widows or other softwares not working properly: In a used computer (particularly older than one year) when newly installed windows or any other softwares do not works properly , it may be due old CD or DVD ROM drive which fails to read any application file(s) of the windows or the softwares installed recently. For the windows setup use new CD or DVD ROM drive and for other softwares one can alternatively ( escape buying a new CD drive) use the softwares by coping it first in a drive of the hard disk and reinstalled from the hard disk.
