i have ASUS H81M-A motherboard with integrated graphics. my tv was connected to hdmi and pc monitor to dvi. everything was great for over year and then hdmi stopped working. out of laziness i just plugged tv to vga port and didn't bother since warranty was over.
unfortunately today my dvi stopped working too.
at the moment the only port working is vga.

what's wrong and how to fix it?
