Can bent CPU pins cause this?

Hi, i recently accidentaly bent 2 cpu socket pins on my asrock h97 board. I have bent them back and everything seems good, except that whenever i plug a monitor into my onboard VGA port, its starts to flicker and eventually Blue Screens. However teh HDMI and DVI work fine. I use a dedicated GPU so this isnt much of a problem but i would like to know if this is because of the bent pins. If not, then i can try get a refund. Anyway, help is appreciated. :)
