Monitor gets no signal

[Oppobrium]

So today I got home from school and turned on my computer, after a while I noticed that the monitor is not getting anything so first things first, I turned off the PC and unplugged everything for about a minute. After a minute, i only plug in the monitor, everything runs fine but still no signal on the monitor. I decide to test if my Video card is dead so I take my GPU out and put it into my bro's computer and it turns on fine. The weird part is when I plug my computer with all original parts inside into my brothers monitor it turns on. This time i decide to plug my monitor into my brothers computer and i see that it works as well. So i switch out the DVI cords and try to plug it into my computer with my monitor and it still doesn't show up anything.

Sorry for the long post but does anyone know what I can do? Thanks.

So cliffs notes is that:

Your computer + your monitor = No go
Your computer + bro's monitor = Yes
Your bro's computer + your monitor = Yes
???

So you've just proven that you have known good parts all around, now as to why the two won't work together...

If your video card has d-sub instead of dvi, have you tried that?

nope it doesnt, i think now its showing signs that my gfx card is dead, i just replugged it into my brother's monitor and its showing nothing anymore, i'll get a spare card and see if anything changes.
