I have recently attempted to create a custom built computer for the first time, i have followed guides and got the computer all made but when i power it up it makes a loud high pitched noise! how do i get it working properly, it turns on theres just a huge noise. I also have a second question, my new computer has a 320mb 8800GTS graphics card in it, and has 2 DVI slots on the back of it, my monitor has a DVi and a VGA, but i only have lead for VGA, but i have 2 apadtops which turn a VGA into a DVI. But the adaptor only works in the graphics card, if i put an adaptor on my monitor it doesnt fit, will the monitor still work?
