PC Blank Screen Problems

Hey guys, I've built a pc a few months ago and I've been having some issues with it, the screen turns blank randomly, not off, but blank. I can tell the screen is on because my monitor (see specs) has a light that is blue when it is receiving a signal.

I suspect this is because of workmanship or something, I've been very careful in handling my components. I suspect it is either the motherboard or the PSU because when it did this before and now using a can of compressed air on the psu generally fixes the problem. At first I suspected my video card but then I moved the hdmi cable that I had plugged in to the onboard intel graphics, and that worked just fine... till it got the blank screen too... that's what leads me to believe it was the motherboard.

Not sure why I'm having these issues I take care of my pc and it gets very good cooling (air flow is near perfection!) I'd appreciate any help the wise tom's hardware forumgoers can offer
