Ngenet was fun, eh even hangs my computer, I restarted, just want to go to bios .. already hangs again ... wah would be very upset ... when before is okay .. but after I check my computer a few things could be a flame and does not hang anymore .. From this I can conclude why the computer could hang

1. As a result of software (software)

* Computer may hang because CPU too hard to work because the software is run too much for the ability of this computer. How to view CPU usage simultaneously press the Ctrl + alt + del to open task managar, click the Performance options. The most severe load applications according to you, see the CPU graph, if too high now be careful, the CPU may overheat and damage
* Due to viruses, trojans etc.

2. Due Hardware (hardware)

* Ram problem: try to wind direction from the CPU is not directed to RAM, so that the hot wind that arises from the CPU does not make the ram go hot
* Look at what the external BIOS memory is activated (enabled)
* Processor is damaged: nah this one ever made me confused beginning, the computer hardware so far that I know most often broken is the processor (CPU) provided the perfect coolant. that time I test computer always hangs, I try to test the vga, memory, mainboard all okay. apparently causes the processor is too hot until it reaches 80 'C.. wow, headsinknya fan does not fit its position on the processor (CPU) so that heat is not absorbed by the CPU FAN
* Damage to the power supply: nah this one is also made initially confused, because all components are already tested and all devices do not have any problems, fitting to open a new power supply found out, plug the power supply on the mainboard there is a broken cable so that the incoming electrical current to the mainboard is not perfect and hangs komputerpun

In fact there are many causes of a computer could hang, but not all cause the same, therefore we need to detect one by one to the software and hardware to work perfectly
