Hope this helps you figure out what to do next. Thanks for using Fixya!

Put just the ram back into the motherboard, the pc will not boot without processor, ram and graphics pluged into the board, check this, if it will still not boot and you still get 3 beeps its a memory(ram) problem, and you will need to replace the memory stick.

Memory  6 x 1.5V DDR3 DIMM sockets supporting up to 24 GB of system memory (Note 1)
 Dual/3 channel memory architecture

Definitely not your monitor. It is either a CPU or a Memory problem, is this a new build or did an existing computer suddenly start doing this?

Is that your motherboard, the Gigabyte 7VM400M ?

Could have been dusty. Find a copy of Memtest and run it to check things out. Errors could mean a bad stick or bad slot.

Im gonna take it that "yup i'm hear the any beep" means you do hear a beep.

So first If it has an onboard vga card. remove the second vga and hook the monitor up to the onboard and try to boot.

Second try the Power Supply, make sure whatever power supply you use has enough to handle all the equipment in the unit.

If those two don't solve the problem, then you have a bad motherboard.

it would be supporting but it would generate more heat which has been disaster to ur processor simple way use less than 800ddr ram
