Recently My old LCD monitor started to screw up, it would constantly lose signal. So i set up my old crappy CRT Monitor to use until i got a new connection cord. But i had to go use my LCD screen to change my monitor to the CRT one. But now my CRT completely died. I just bought a new cord for my computer but all i am just getting "no signal". SO i have no idea what is wrong or what i can do about it.
