Did you hear any beeps?

Apart from cable faulty there is a culprit for no signal in monitor that is with RAM.

Did you know how to remove and replace it again in the slot?
If dont know ask me i will explain.

Did you have internal speaker on your pc?

See basically we should hear beeps without the presence of RAM on the motherboard.
If you have faulty RAM slots you hear beeps but you didn't.
I think may be your power supply unit is faulty, you said that it keeps powering off and on by itself?

first i had it plugged in to the monitor, and then i tried unplugging, still no sound.

usually on my other pc it would make a sound if i didn't have any ram inside but now it just turns the pc on for 5 seconds and turns it automatically of and then again on and off like in a circle motion.

connect everything switch on the pc, press F8 immediately the startup of your pc, enter into safe mode.
If unable to do anything, tell me your graphic card model and power supply rating.

The card mentioned need atleast 400w power to run good!
Did you have atleast 500 watts power supply unit?
Try to remove the card (if you know then do it otherwise don't)
