Bran new gaming PC keeps getting blue screen.. Need assistance please!

[Aaoi]

So basically my story is, I built this PC with all new parts ordered online. for the most part everything ran great but one day I randomly got a blue screen and that worried the hell out of me because its a bran new PC I put a lot of money into, so after a restart It didn't happen again for a month or so,but after that it became a every other week thing. I've also notice if I slightly bump the case with my knee or anything it will cause the blue screen, so I thought maybe something wasn't seated right so I re-seated everything and things seems to work for abit but every now and then I'll still get a bluescreen and its really starting to worry me.

I have no idea where to start to see whats causing it so I could use some of your guys help please.

My PC specs are listed below,

-Intel i5 4670k - 3.4GHz
-MSI Z87-G45 Gaming Mobo
-EVGA GeForce GTX 780
-16GB Corsair Vengence DDR3
-2TB WD HDD
-120GB Kingston HyperX SSD
-Corsair 850W Professional Series PSU
-Frio Advandance CPU Cooler

Haven't done any huge scans but I did a couple basic scans and came up with nothing, I don't download or goto doggy things, I'm pretty sure its not a virus but I could be wrong.

Well I once had a virus infested laptop. My laptop used to run very slow. I didn't realize it was virus causing this problem until I got an BSOD. After a whole system scan i caught alot of viruses. But it was late already. They have already corrupted My OS. I couldn't play music,videos or anything. Even after windows reinstall not all the problem was fixed. My laptop automatically shut down after every 1 hr. Now it lies in some corner of my home collecting dust.
