It is probabally not necesssary, but it is a good idea to check the monitor on a second computer. If it works on the other computer, then it is very likely the video card.
My son knocked over the tower on my PC and the monitor turned off. Now I can't turn it back on. It keeps saying 'no signal detected'
I have unplugged everything - plugged it all back in - even got a new monitor (an old one from a broken computer we had) and hooked that up - no good.
I tried a different cord.
I opened up the whole thing and cleaned it out. (although I suppose if anything was unhooked inside there I wouldn't know...)
Any other ideas?
THANKS FOR ANY HELP!!!
