ok so my friends computer is acting up. When we turn on the power all the fans and drives seems to be spinning but nothing is on the screen. You don't hear that stactic sound when the monitor is activated.
I did a whole bunch of test. I disconnected all the unnecessary stuff and left one cd drive and the main hard drive. there still is nothing showing up as like there is no power to the video card, but I put a working video card into it and nothing is showing up.
Except I power off, unplug power cord connecting to the mother board, re plug it back on. Then I turn the comp on and the screen turns on! what? but it usually gets frozen when u see the win logo with the animating bars.
I even tried using a working machine power source and pluged it in. Same problem. I came to a conclusion that its the mother board at fault and is dying.
Everything turns on except no video display, video card works fine. I even put the hard drive into a working machine and its starts up fine. So right now nothing is showing up, only fans and other devices running but no video display.
