I am attching only the 24-pin and the vga. I am not seeing any thing display on the monitor. When I have every other cables plugin, I see nothing either, that's why I only have 24 and vga plugged in.
Probably not, you also need to plug in the seperate power connector for the CPU - this is either 4 or 8 pins, and is right next to your socket.
Look for something like this
In order to get to or past POST you need the following items.
Without those 4, or 5 things, you will get just a black screen, you can ignore 4 if you wish, but it will over heat quickly and get you back to not being able to POST till it cools down.
