right.. the first time.. i remove everything that is in white.. i did not touch the red components. i installed it.. tried to install nividia graphic card and the via hyperionpro hardware. and both stated can't detect any hardware. i thought it might be the hardware components that caused it. the 2nd time.. i only remove all the driver. leaving other components untocuhed.
still can't detect.. 3rd i tried to remove only hardware.. Can't detect again......

why is that so?

Did you install drivers provided by your hardware maker after installing the "nilted os" or atleast integrate it in nilte? If you remove all drivers it should still work as long has, you have not removed the hardware support and install the correct drivers for your hardware.

The only other thing I can think of is you might have disabled the hardware plug and play service under services in nilte.
