If we use Desktop Computer then most us surely have faced this problem few times or at least once in the life span. Occasionally it happens that Desktop Computers doesn’t take startup. As nowadays computer has become a pretty much important part of live as it makes our life much easier and also it plays a very important role in our professional life. There are various startup problems for computer I listed few of them with their symptoms along with their solutions.
After Switching on No Display on screen and Beep….Beep Sound from Cabinet:
This seems to be a problem of Hardware related to RAM. To solve the Problem follow the steps stated below :
- Switch off all switches of computer and disconnect it from electric supply.
- Open the Cabinet from one side with the help of a Screw Driver.
- Now bring out the RAM Chip from the Motherboard.
- With a help of soft painting brush clean the RAM Slot on Motherboard gently.
- Hold the RAM chip on a flat clean surface and with the help of a eraser rub on the golden area of the RAM chip which are situated at the bottom edge of the RAM. Clean the both side of the chip with eraser.
- Now with a clean paper clean the rubbed area of RAM chip.
- Now put the RAM Chip back into the slot on motherboard and fixed it properly and fixed the slot clip on both side of the slot.
- Close the Cabinet.
- Connect the Power Cable and Power On the System again and try to Start the computer.
**** If the computer still doesn’t starts and the Beep……Beep…….sounds comes out then that means you need to change your RAM and it has malfunctioned or damaged or your Motherboard’s RAM Slot is damaged and you have to change the RAM or Motherboard. I suggest you should also try the whole procedure but putting back the RAM on the other RAM Slots of the Motherboard.
After Switching On the Computer No Display On Screen and also No Beep………Beep…….. Sounds from Cabinet but the CPU Fan is Running:
This seems to be a Hardware related problem, most probably caused by RAM and/or Add-on Cards. To be able to start the Computer again just follow the steps given :
- Turn all switches related to Computer Off and disconnect the computer from electric supply.
- Open the one side of cabinet with help of a proper screw driver to have access to the Motherboard.
- Bring out RAM and all Add-On Cards from the slots of the Motherboard carefully.
- Now clean the RAM and all other Add-On Cards with the method mentioned earlier in this article.
- Clean all the Slots of the Motherboard with a soft painting brush carefully.
- Now connect the computer to power source and start it and see what happens.
a) If No Beep Sounds Comes Out :
It means either the Motherboard is damaged or there is a short circuit within the Cabinet and the Motherboard.
Now disconnect all connections to power supply and Now unscrew the Motherboard from the Cabinet and disconnect all the connection except the CPU portion and the Cabinet speaker and put it over e foam of mattress and then reconnect only the power cables of the SMPS with it.
Now power on the computer motherboard by connecting the SMPS with power source and turning the electric supply, then short the connector pins of the Power Switch of Cabinet on the motherboard with the help of the metallic part of the screw driver. Now if Beep…….Beep………Sounds comes out then it means that the Motherboard is working properly and either the Cabinet or the Processor is faulty and Creating all the problems. But it’s rare that the Processors become faulty so I recommend the Cabinet should be changed as it’s causing some short circuit the Motherboard. If after changing the Cabinet it doesn’t work out then you should give a try with another Processor. If there are no sounds coming out it means that the Motherboard is not working properly and it needs to be changed.
b) If Beep……Beep…… Sounds Comes Out :
It means The Motherboard is working well and till the connections so far there is no short circuits between the Cabinet and the Motherboard.
Now disconnect all the connections to electric supply and put the RAM on the proper RAM Slot and fix it properly and then start the computer again, if Beep….Beep….. sounds comes out then reset the RAM on the other available slot and then turn on the system again. if there is still sounds of Beeps coming out then it means the RAM is faulty and it needs to be changed. If there is no sounds coming out then look if system starts properly.
Now if the System works now fully correct then just turn it off and disconnect from power source and now put only one of the Add-On Card on the Motherboard but except the Graphics Card if there is any.
Now turn On the System again and see if it’s staring again properly. If the System stops starting again then it means that lastly added Add-On Card has the problem and you may replace it or not use it.
If the System Start again properly then again follow the above procedure and add another Add-On Card on the Motherboard and start the system. Add all of the Add-On Cards one by one until the system stops Starting again and that means if the system stops starting again the last added Add-On Card is creating the fault.The Graphics Card should be added at the last, after putting all other Add-On Cards On the Motherboard.
After Switching On the Computer No Display On Screen and also CPU Fan is Not Running and No Power LED Light is Turned On of the Cabinet :
This Problem Occurs mainly due to the either or any combinations of the following – Faulty Power Source, Faulty UPS, Faulty SMPS, Faulty Cabinet Switch.
To solve this problem follow the steps given :
- Check the main power source to which UPS is connected.
- If the Power Source is good then check the UPS by connecting a good working Bulb (say 100watt) to the Output Power Source of the UPS and then turning on the UPS. If the Bulb turns On Brightly then the UPS is working properly. If not then the UPS is faulty.
- When the UPS is connected to the SMPS then Turn on main power and the UPS and then try to start the computer by short circuiting the power switch pins on the motherboard. If the computer doesn’t start then the SMPS might be faulty to be confirmed You should test the SMPS Multimeter for Rated output of the SMPS.
If the Computer starts by above procedure then after disconnecting the computer from all power sources then at first connect the Cabinet Power Switch Connector to the proper Pins on the Motherboard, and connect all the Power Sources properly and the Start the Computer and then if it not Starts then it means the Power Switch of the Cabinet is damaged and needs to be changed.
