Newly installed 780 causing my computer to boot to black screen w/ B2

I installed a new MSI Nvidia Geforce GTX 780 into my MSI Z68MA-G45 motherboard today. However, every time I boot my computer, my motherboard will do the regular "all clear" beep, but then display a black screen with a white text underscore at the top left corner and a "B2" at the bottom right corner. This screen will stay there for upward 2-5 minutes. During this time, every 20-30 seconds, my motherboard will produce a short beep. Finally, the windows splash logo comes up and it will boot into windows. In this process, however, it seems to be skipping the POST, because I cannot access my bios. If I attempt to access my BIOS by spamming delete until the black screen with B2 ends, my computer will just display a black screen and do nothing else.

I have scoured the internet trying to find help for this problem but nobody seems to have it resolved. Please help!

  3. Yeah, there is a reason that PSU is so damn cheap. Your PSU is the issue. And even if it is not, at least you get a reliable unit when you replace it and you won't run the risk of destroying your PC with that thing.

    Sorry, bad news I know. But NEVER cheap out on a PSU. NEVER...

    How much should I be paying for a PSU? And even if I did buy a new PSU, what if I still have this problem?

    Start at the most likely point, right now, its your PSU.

    Is there anything else I can do to make absolutely certain it's the power supply? I don't really have the money to just drop 90 bucks on a new one...
  7. Yes you're power supply is Tier 5 - worst of the worst,NOT RECOMMENDED. Replace ASAP if you have one. Source: http://www.eggxpert.com/forums/thread/323050.aspx

    Not without trying a known trusted unit.
    Consider that a new PSU is an investment to keep your system SAFE.
    But I am 90% sure it will solve your issue.

    Why do you want a new mobo? Yours is fine and so is that one you have chosen. There is not really a tiered system for mobos.

    My mobo is very small and quite out of expansion space. Plus I really want an optical out so I can use my Astros with surround sound

    Alright, thank you :) I also noticed this new line of motherboards with the Z87 chipset has come out alongside this "haswell" processor line. Should I go ahead and pay the extra money to make the jump, or will my 2nd gen i7 be good for a few more years to come?

    Uhm, if you had the K version I would definitely say DONT. But since you don't. Its an option. But not yet... Give it a while. Maybe Ivy Bridge-E has a nice offer.

    Would an Ivy Bridge-E have a possibility of fitting into LGA 1155?

    Nope, but neither can Haswell. :D Haswell is socket 1150.

    No there is not but that is a good motherboard you're looking at i did a few builds with it nobody has complain to me so far.
  18. Have you pulled the gpu and flashed the mb bios?? A lot of the x68 and x77 chipset needed bios updates to fix gpu post hangs or black screens.
  19. Thanks guys. I'll order a new power supply and motherboard and get back in a week or so with the results.

    P68 = no integrated GPU. So you can do this with your old card.

    LOL then you only have the PSU option.
  24. The PSU didn't help. I bought the exact one you listed, Novuake, and I still have the same problem. What do I do now?
  25. BorrOw and older gpu. Download from your mb vendor the newest bios file and put it on a USB stick. Inside the mb bios is a bios update screen. Run it and update your bios.

    Could I just take out my GPU? I can still see the display, even if I don't have a GPU in.
  27. You can Do that too. Thought you dd not have onboard gpu.

    I think my cpu defaults as the displayer when no GPU is in there. Idc if it's that or black magic, cause either way, it works :P

    The solution is not psu, or the hdd. You need to update your bios. I have encounterd this exact problem.

    I'm having the same problem as OP except with a 770. The same post-skip problem and i cannot access my BIOS to manually flash it. Thus far any attempts to update it with MSI LU5 have failed, any ideas as to how to resolve this?

    **Edit** I cleared my CMOS and still no luck, but when i mash DEL at startup now it says 'Entering Setup' at the bottom left of the boot screens (A2 + B2) and then proceeds to a black screen after the 2-3min B2 screen
  31. ughg I love that when people have a problem the consensus is always look for a component to criticize. Its nlikely that the problem is your psu or power related. apart from the fact that gpu's use next to nothing while posting of course, most are set to lower clocks than idle even for boot.

    To add insult to injury, I am having the same problem currently (black screen with blinking cursor during post) and im using 2x1500w supernova's so.....
  32. Did this ever get resolved?

    I am having the same problem... Gateway DX4380 with A10 5700 mobo and the card I installed is a GTX 750 TI SC.

    Wonder if the card is dead? I am going to try it in a different computer today.
  33. I really feel bad for not coming back and providing a solution, and I also feel really bad for necoposting, but I really want people to know what the solution was. The issue ended up being that I had to update my BIOS. IIRC, I also had issues where the computer would freeze randomly. This second issue was fixed by updating my NIC drivers. I hope this helps somebody, I know it gets frustrating finding troubleshooting threads on google with no final definitive answer, so hopefully this helps somebody, even if it may be 2 years too late :(
