One moment you find the computer that you normally wear a sudden die-total, the computer can not boot and the screen does not display anything alias blank. So what should we do ..?
To diagnose the cause of computer malfunction or die total blank, we can do some checking as below:
1. Make sure first that the damage occurs because the computer can not boot or have a monitor that is dead.
For that let's see whether the monitor indicator light lights up, and try to unplug the VGA Monitor, if the display monitor to normal by displaying a picture or a message such as "No Signal Detected" then the damage was contained on a computer.
2. Make sure the Power Supply Works well.
Open the CPU casing and then restart the computer by pressing the power button and note whether the indicator light on the motherboard turns on and fan spin Processor? If it still lights up the possibility of power supply is functioning properly. However if the CPU does not show "signs of life", try to manually check the Power Supply.
3. Clean all components on the motherboard
If necessary, first remove all the components such as Processor, Memory Card-card and other extras. Clean dust and dirt with a brush and vacuum cleaner. If there is use of cleaning fluid is also "electrical contact cleaner" to further clean the dust that sticks to the pins on the IC or electronic component component - the component.
4. Raft back the CPU and try on again, but should not be installed to hard drive first.
Usually there are several things will happen:
* The computer is on a normal (you can enter the BIOS) but can not boot,
this is ga ga a problem because the hard drive is installed. Shut down and plug the hard drive and then on again, when successfully booting means that the problem is almost complete.
* Computer beep sounds,
means there are usually components of RAM and VGA card with problems, try to install again revoked or replaced with a still functioning well.
* Computer still can not boot and no beep sounds.
unplug the BIOS battery, and try to replace the first aja RAM or VGA card of his with a still functioning.
* RAM and VGA card has been replaced but the computer still remains blank,
This wah serious damage usually occurs on the motherboard or processor. In my experience most of the motherboard is damaged (my friend said most of the power transistor), this occurs for example due to power electricity grid is not stable. If no processor is "idle" borrow wrote to confirm the damage.
Thus diagnosis blank computer malfunction or total dead, sorry if the explanation is unsatisfactory, I wait for sharing about how to fix computers blank-die total of all my friends, thanks.
