The Inform system hardware error. 
If, after the POST progress, the system informs the error in the hardware, then the problem is the CPU fan cable attached to the wrong place. Although showing signs CPU fan spinning, some motherboards require the CPU fan's cable is attached to the right place. On the motherboard there are several places to provide electrical power to the CPU fan is the same shape. But if we look more closely at the board, indicating there was writing, that the plugs are labeled CPU fan or power fan. CPU fan cable must be connected to the CPU fan plug, not the fan power.
The solution if the problem happens is a manual check and see the writing on the motherboard. Make sure that the cable is properly tercolok the CPU fan and not on the fan power.




Keyboard and Mouse Not Detected.
If, after the POST run, keyboard or mouse is not detected and stopped the system proceeds, the possibility of the problem is on the keyboard or mouse is not installed properly. When the keyboard is improperly installed or damaged keyboard after the POST progress. Usually the screen will display the warning "No Keyboard Present" and a system to hang or stop. When the mouse is not detected, the system will go into windows, but will appear before a warning dialog box that there is no mouse on your system.
So the solution is to check the keyboard cable is stuck on the I / O on the back of the casing. Check that the legs of the cable is intact or broken. If possible, check the other PC keyboard using the function normally. Perform the same procedure to check the mouse. When the mouse or keyboard is not damaged, the other possibility is one or two controllers on the keyboard and mouse damage. When this damage happens, you inevitably outsmart emotion, for example by using the keyboard or USB mouse type.

PC system slowly when executing the data.
If the PC system was slow in executing the data problem is probably one of the differences between the new motherboard with the old motherboard is the wire that served as the data traffic. In the old motherboard, an IDE cable to hard drive and 1 IDE cable 2 to the CD-ROM form and the same type, so interchangeable. Some PCs even use one cable for these two types of peripherals. In a new motherboard, hard drive cable that is included is the ability to follow the latest hard disk that supports Ultra ATA-66 or ATA-100, so the hard drive cable is only intended to connect the disk to the motherboard, not to connect the D-ROM to the motherboard. If this cable combined, then the data transfer capabilities will follow the lowest speed read.
So the solution is to check the path kaber IDE 1 and IDE 2 in accordance with the manuals and make sure that pengkabelannya systems have been installed correctly.

The lamp-light on the front panel of the chassis is not lit properly. 
If the lights on the front panel of the chassis is not lit properly then the problem is located at position errors cables chassis front panel is connected to the motherboard.
And the solution is to check the cables that were installed in accordance with the manuals included on the motherboard. When the IDE LED lights lit, the possibility of installation kebelnya tebalik. Similarly, the indicator lights of the other. One of the easiest ways to install this cable is using wire colors are on the front panel of the chassis. Normally, colored wires (green, red, orange, blue, and so on, depending on the brand chassis) is a cable that is connected with positive electricity, while the cable is black or white color is connected to ground or to a negative position.
