Hi all,

I just finished putting together my new build, but I'm not able to boot. Dr. Debug shows error code 0x15, which is supposed to correspond to "Pre-memory Northbridge initilization is started." The computer sits at "15" for a few mintues and then just shuts off. I'm not sure what info to include, but here are some specs:

ASRock Z68 Extreme4 Gen3
i5 2500k
8gb Kingston HyperX 1600MHz RAM
MSI 560 Ti Hawk

Thanks so much!

sure, the power supply is an OCZ ZX 850W. the computer turns on, all the fans are on, but the dr. debug display remains on "15." and no, the display never turns on. thanks!

hmm process of elimination is what you need to do first thing is remove your ram and boot up on 1 stick try each stick see if you got defective RAM stick next try your video card if got 2nd one laying around and then see
