Hi and welcome to FpcH

Do you have another video card - an old one - that you can try ?
If so - swap them over.

Do you have on-board video that you can try ?

i have on board intel graphics, i plugged the hdmi cable into motherboard hdmi but still nothing came on screen. i took the graphics card out when doing this...i dont know what to do

It could be a fault with the HDMI cable.

Are you getting power to the motherboard?
Are fans turning?

If you have a volt-meter check the PSU output at the connection to the motherboard.

i tried new hdmi cables so it cant be that. i rebuilt the pc last night and now it wont even power anything! before the fans were running but now no fans turn on but the mouse lights still turn on. could it be my power supply?

could it be my power supply?

Looks like it could be.

Do you have an old PSU to try - it doesn't have to be the same wattage.
Try it using the on-board graphics - leave your Video Card out for the time being.
