I just completed my first build and everything posted / worked just fine. I got Windows installed fine and all components were recognized. But every time I turn it off for awhile and come back to turn it on, the system will not boot until I physically remove the graphics card and put it right back in. Then it will boot, but the problem rinses and repeats. When I say will not boot, I mean the system turns on, fans go, everything has power (including GPU) but no signal will reach my monitor. The MoBo I'm using displays the Dr. Debug code "b2" which apparently corresponds to "Legacy Option Rom Initialization", which I have no idea what that means. Anyway I just shut it down, pull out then put back in the G card and it boots for one time only. I have tried the card in another slot and the same thing happens. System boots fine when graphics card is out of system but that doesn't rule out the MoBo by any means I know. Heeeeeeellllllppppp please.

Clear the cmos, if it doesn't solve it, update the bios to the latest version.
Check with just one/two sticks of ram.
If it still doesn't fix it, the motherboard could be defective.

I hadn't, so I just did. It booted for the first time just like when I remove / put back in the card. But it failed with the same debug code / symptoms after a reboot.

Ok so this is new. Removed all 4 sticks of ram. Put 2 back in, posted once just like when I removed the GPU, but then on the reboot it failed with the same code / symptoms. Put all 4 back in, same story.

checking latest bios, pretty sure i already have it.

Was not in most recent bios, however, after I downloaded the most recent (did not install yet) The computer has boot up 5 times in a row no problem. I HATE INTERMITTENT PROBLEMS.

Will have to wait half a day, let it sit, see if it comes back, then I'll try new bios.

It came back. Same issue. Updated BIOS to most recent, no fix.

Bad MoBo?

I've read online in some places this b2 debug code is pretty universal, like getting it replaced might not fix it..

yeah its your motherboard im 99% sure it is, either that or it is your PSU but normally if you psu is failing it will just randomly start(if its not completely dead) but yeah after you reinstalled that stuff it booted narrows it down to the motherboard and CPU

Unfortunately I screwed up the tests last night. I left the card in the whole time i did the ram tests and bios upgrade, So its either the graphics card or the mobo. I ran the ram tests again today with the graphic card out and it booted perfect every time. the graphic card works in neither pcie slot. Newegg RMA time for GPU?
