Hi all, I am doing my first custom gaming build, and am having some boot problems. I would appreciate a little help diagnosing the issue if you'd be so kind.

First off, here are my parts from Newegg. All are new except for the power supply and hard drive, which was pulled from a working unRAID tower.

BIOSTAR TZ77XE4 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS
Item #: N82E16813138354

CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Low Profile Desktop Memory Model CML8GX3M2A1600C9
Item #: N82E16820233186

MSI N560GTX-Ti Twin Frozr II 2GD5/OC GeForce GTX 560 Ti (Fermi) 2GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support
Item #: N82E16814127608

Intel Core i5-2500K Sandy Bridge 3.3GHz (3.7GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 3000 ...
Item #: N82E16819115072

Power PC and Cooling 610 Silencer Power Supply

WD 1tb Caviar Black Sata Hard drive
----------
Basically once assembled and with the PSU turned on, the motherboard shows power, and when I hit the power button the motherboard turns on, CPU fan spins, and it looks like its booting, but no video shows up on the display. This board does not have onboard graphics, but the i5-2500K has graphics capability. (Not exactly sure how that works) I have also tried it with the MSI card installed, also no video. I have also tried another cheap PCI graphics card installed, also no video.

Also, there is no BIOS post code being displayed on the onboard motherboard display. And when a force shut down, the BIOS post display flickers once and disappears.

I have tried moving the RAM around, taking one stick out and testing each slot with only one stick per boot, and did this with both sticks, nothing. I have tried every dual channel configuration with both sticks. Nothing.

I have tried reseating the CPU. Nothing.

I have tried it without any graphics card installed, just using the mobo DVI. Nothing. (would the i5-2500 show some video here?)

I have tried posting the mobo both inside and outside of the case. Same result.

I have tried it with and without a hard drive in the data port. (would that make a difference? I mean wouldn't it post to BIOS without it?)


I am wondering, is the fact that I am not seeing any BIOS CODE, of some sort, on the onboard motherboard display mean that the motherboard is defective?

Your help is greatly appreciated!

Thanks Rolli, yes I checked the list and performed it well. Went and bought a Sabertooth Z77 which booted up first time. I had heard Biostar had upped it's game a bit reliability wise, but not the case here. Thanks again.
