Fix BSOD error 0x7B without reinstallation
You are probably missing a device driver, I would guess the one for the motherboard.
Try to repair Windows as described in How to Run a Startup Repair in Windows 7. This mode of soft installation will scan your Windows 7 computer for a startup problem and try to fix it so your computer can start correctly, especially in your case fixing missing or damaged system and driver files.
If this doesn't work, get the driver from the ASUS website and add it in during the above installation process.
