I was all excited once I received my shiny new EVGA GTX 780 SC ACX. I installed it hastily, yet with tender, loving care. I go to turn on my system and I'm greeted with a successful POST, okay good! Then the bad news....my computer just hangs on a black screen with "B2" in the bottom right corner and a blinking cursor in the top left. I also installed a new SSD I received with my new card, however I tried booting off both that and the old hard drive. Same Issue....so at this point I'm blaming the 780. What can I do to fix this? Or should I fill out and RMA.

How about some more details on your system? Motherboard, power supply, processor, OS etc.. etc... The more, the better. What are you using to connect to the monitor? Does your system have integrated graphics? Did you have a previous GPU installed in the system? Is the power connected correctly to the GPU?

Okay, does the system boot normally if you put one of your 570's back in? (assuming you still have them). Also, I'd try booting the system with just your original OS drive connected if you still have the SSD installed.

Sadly I became frustrated and had to get ready for work so I didn't get a chance to try one of the 570's. I will this morning when I get home. I also have since decided to wait on the SSD until I can get the 780 working. I have been doing some research while at work and I've noticed lots of MSI users have had this issue and needed a BIOS update. I used the app from MSI to flash it, however I guess there is a newer BIOS version that Live Update 5 did not pick up. Thats next on my list. Thanks for the replies, I'll report back in the morning once I throw in a 570 and update the BIOS once again.

As you stated, pretty sure you just need a BIOs update and it should work. Let us know when you try that if it works.

If you update MSI motherboard BIOS and I mean on other motherboards too, better always update BIOS manual. I can't remember how many times people finished in service or RMA with completely functional MSI motherboards before their BIOS Live Update. Instead to download and flash manual they will remember that devil. I wish you luck with new 780.

I've tried flashing the BIOS today and I know I downloaded the right version...this is my board. MSI Z68A-GD65--G3 I download Bios 25.8 and I do the USB flash drive install of it, it completes successfully...and my motherboard is still at Bios version 23.7....what gives? (Yes I've cleared CMOS)

Devizion...you're not the only one with this issue. I also have an MSI Z68A-GD65-G3 with Sandybridge I7-2600K and was running two 570s in SLI. I just bought two 770s to replace them, and I can't get my rig to even display the BIOS. I get the single curser and B2 error. My system works just fine with the old cards, and I also tested it with a Radeon 5870 which work as well. It's something with this mainboard and those video cards. I REALLY don't want to flash the BIOS as the MSI BIOS were so bad when I got this board I had to downgrade them to maintain a stable overclock. Did flashing the BIOS work for you? A couple of other people have been able to get it to work by reinstalling a working card, switching video adapter mode to Legacy, and replacing the cards. However, this was with a Gigabyte board and not MSI. I'm going to try it though. EDIT: There is no Legacy mode in the MSI BIOS. Additionally,I found several other MSI board owners having the same issue. MSI has not provided a solution as of yet, and several users are reporting major problems with the new BIOS updates. I can tell you this: I will never again own a MSI brand product.

Welcome to forum. And your problem is...??? I see one post here... If you have problem with graphic card and you are not sure what cause that graphic or motherboard your next step is to call some PC service, some friend who have AMD motherboard, or EVGA, ASUS, GIGBYTE, ASRock and try your card there. Maybe is their service right, maybe wrong...

There are a number of posts regarding this issue on forums here, Intel, Nvidia, Asus, TomsHardware and elsewhere. The issue involves the GTX 780 and motherboards, presumably using the same chipset. The next step is to file a complaint with the Consumer Protection Agency and other consumer assistance sources. I have contacted, via forums, many other users with the same problem and no resolution. It's apparent from your responses that EVGA has no intention in taking any action to resolve this problem (contact "some friend" is your solution). EVGA has always made a good product, however when there is problem, their technical support is one of the worst in the industry.

Devizion, please try the BIOS update again by putting it on a flash drive and when running it right click on it and run it as administrator. Looking at the BIOS update on MSI's site it notes: *Please download and execute the file in USB pen drive only. System will restart several times to update ME firmware after updated system BIOS. Please DO NOT remove the USB pen drive until ME update sucessfully. It does say it enhancedes PCI-E display card performance and we have seen where some motherboards require a BIOS update to work with the newer 700 series cards, even if it is a new chipset. Please post back the results. On a side note, MSI miss-spelled "sucessfully". If you are in contact with them to you might want to mention it for them to fix.

Also make sure your video card has the latest bios on it. That seems to be the trick with this problem, not the MB bios. I am on an MSI P67A-GD65 MB with BIOS 1.19 on it and my GTX770 SC ACX works just fine with it. My GTX770 SC ACX came out of the box with the newest bios available on it. Make sure your video card has the latest bios available on it. If needed put the card in another computer that it works with and check the bios version of the card.

I disagree. In this case this particular motherboard has to have the latest BIOs on it to run with the GTX 780.

I would like to point out that your issue is that your motherboard BIOS is not successfully finishing the POST process. I don't know why you are claiming that it will POST fine when clearly it isn't.

I've used their software and my board will not flash up to the 25.8 version. I've tried about 10 different times. It goes through the entire process, says complete, then still displays the same version. So...no luck still.

That doesn't bode well for me then. I haven't been able to try to flash mine yet. Tomorrow night I'll give it a go. This mainboard has always been flaky with the BIOS. I really hope I don't have to replace it. I can't really justify going to Haswell when my Sandy clocks in at 4.7GHZ on air.

Well revenant...I bricked my Mobo a few hours ago. (At work now) I wish you the best of luck with the MSI board, I however am not going to bother with them any longer. I just purchased a ASRock Z77 Extreme4 LGA 1155 Intel Z77. Hopefully it'll work out. I figure if im investing 600+ dollars on a new GPU, I might as well flip a new motherboard as well. Good luck man!

Well good news for me I guess. I did the BIOS update to the newest MSI BIOS and my motherboard came back intact. I haven't tried overclocking yet so there's still that to deal with, but at least I have video again. Oh yeah...the video cards work now! So problem solved. ...of course the BIOS updated OBLITERATED my Windows install. I have NO IDEA WHY that would happen. I had to do a complete reinstall which is still going on. Thankfully, I have a Steambox PC where my old 570s now reside to type this on.

I know this does not apply to all but it does to the majority! Yes, I too fell victim to this dreaded problem. I tried everything I could think of. The motherboard was of a vintage that this card should not have had any issues. I updated the BIOS, video drivers of every version all to no avail. I reseated all internal components, updated the PSU none of which made the problem any better. I looked into TDR issues, driver conflicts etc. I combed over dump-logs finding references to drivers and services of which are discussed at length on the internet in countless forums. Nothing helped. I was about to request an RMA when . . . . . . I sat and pondered the problem. I pondered about in the old days, code was neat and clean. When software engineers were careful as to where they placed their code. Blue Screens were easier to diagnose for the reason that a Blue-Screen is a memory issue. It now, as it always has been. I am not speaking of memory either being good or bad but, of memory and how it gets allocated and scrutinized by the software that gets loaded into it. Sometimes, just the load order can make a difference between software that works and software that does not. When a piece of code was currently injected into a specific memory location, any subsequent write operation checks all current allocated cells. Should a cell be currently in use, another unoccupied cell was located and utilized? Code is no longer written as carefully as it was in the past. If a .dll is currently in memory, current code practices often stomp all over it. Gone are the days of pure Assembly. Assembly is a thousand times, smaller, a thousand times faster, and a thousand times cleaner. Every code writer must check and re-check the stack and make sure that everything is correct. In contrast these days, code is just not as clean and to add to the issue, most, but not all peripheral cards have been stripped of their on-board processors relying on the system’s CPU for instruction cycling. Of course our video cards have on-board however, and the point is all the hand-shaking that goes on in a modern day computer is overwhelming to the best of systems. Speed is not everything, efficiency and good code is the key. The one thing that is often overlooked is this, when software is developed regardless of what it does, the manufacture has a preliminary test-bed system which is void of most of the crap that makes its way onto the average user’s computer. They have to assure that their product/drivers are the only thing running or that little else is installed that might interfere. It then makes it way to systems that are perhaps loaded with crap but still not bogged down with all the garbage that is on the typical computer. They must do and assume this position to test their product. They cannot test on a system with 50-million possible combinations of others poorly written software. They must have a clean system to see just how their poorly written software performs. Often their code for what ever reason, actually works and they stand behind it. After looking into my situation, I realized that I am guilty of performance-tweaking as are many if not most users. Having every piece of software to available to check everything from Frame-Rate, Temperatures, Voltages and so on all for bragging rights I guess. I just as reluctantly as most of you cringed at the thought of blowing away the OS start from scratch. We’ve put so many countless hours into setting the system up and tweaking it until we were more-or-less satisfied that our system X-Mhz faster than Joe’s computer. I decide to take the plunge and rebuild the system. God I hated to do this . . . However, I did in fact recall all the software I had installed, over that past couple of years only to patch with countless updates and again to remove regretting what the registry must look like. Another complaint of mine with regards to poorly written code: If you placed in my registry then DAMIT, remove it. This is another area for which software developers fail . . . Cleaning the registry after removal. Of course some CLSIDs or other encrypted keys are created and the software/developer would have no idea as to just exactly what to remove. You’ll notice that a typical self-help driver fix tutorial will almost always have you empty the registry of specific software related keys but there are always residuals. Listen, it is a fact that, Hardware developers DO NOT sell you Beta-ware products as do Software developers . . . like the games we play. Their code may not be perfect but, you must give them a break and refrain from bashing their products. As for the Software engineers, well, they need to simply stop sucking their 64oz Big Gulp and write some serious code. In conclusion, after reinstalling the OS and eliminating all the crap and you know to whom and to what I refer, the GTX 780 works flawlessly. After applying all MS-Hotfixes (which scared me as well) the card is still functioning perfectly without Black Screens, Blue Screens and without Flicker or Stutter. The fluidity of the game screens attests to this fact and I don’t need FRAPS or ASUS AI or anything else to verify that my machine is still faster than Joe’s. Thank you EVGA for this great video card!
