Hi, this is my very first post, and i need help! 2 hours ago i unplugged my computer and replaced some old ram with new ram and when i connected everything up again, i turned on my computer and my moniter said "HDMI NO SIGNAL." for a couple of hours i reinstalled all of my computer cables and see if that fixed it, NOPE. i checked the input setting on my moniter and it was set as HDMI. i unplugged and replugged for a long time, tried dvi, hdmi and changed the input to dvi, didn't work. Checked the forums numerous times, didnt help. please i need help!
