BSOD while wasnt doing anything, now PC wont start

Hey,

I was playing Skyrim, closed it and steam and only had firefox running, left computer for ~5 min, when came back, I had BSOD. I shut computer and restarted it, now it wont start. I click power on to PC, looks/sounds as if its on, but nothing on screen, no win starting voice on speakers, no piips from box and does not respond to keyboard/mouse nor if I put Windows 7 CD in.

It has couple times before done this, but then it usually starts to work instantly after BSOD or after few hours offline and then reboot. Last time it did this (about couple weeks ago), I changed settings so it would make this log dump file, but now it wont start and cant get the file.

---PC specs:

Windows 7 professional 64-bit
Agility 3 Series SSD, 60 GB
Core i7 2600K LGA115, 3.4 GHz, 8MB
Corsair 600W CX V2 Builder Series, ATX, 80Plus
Coolink, processor cooler, Corator DC
Fractal Design Define R3 Black Pearl, ATX box
Samsung 1TB SpinPoint F3 3.5" SATAII, 32MB, 7200RPM
Kingston HyperX 2x4GB, DDR3 1600MHz, CL9
MSI GeForce GTX 570 Twin Frozr III Power Edition
MSI P67A-GD55 B3, LGA1155, Intel P67, DDR3, SLI/CrossF


Really appreciate all help i can get, as it is now, next step would be on me to take to repair cause dont know what else to do.

UPDATE:
Apparently my main screen not good untill get to windows, so digged up my old screen. On startup it gives this BSOD:

STOP: 0x0000007B (0xFFFFF880009A97E8, 0xFFFFFFFFC0000034, 0x0000000000000000, 0x0000000000000000)

And I can get to BIOS and to Repair Windows option. Win repair mode is of no help and so far BIOS access havent really helped eather.
