Hello everyone,

Since October I have been seeing a B2 error when booting my PC and I know it has something to do with the video card.

System details:
  • - Windows 8.1
    - Asus Z87-Pro(V Edition) - BIOS version 2005
    - Intel(R) Core(TM) i7-4770K
    - Patriot Viper 3 16GB (2x8) Memory
    - Sapphire Radeon HD 7970 Ghz Edition 3GB GDDR5 VAPOR-X
    - Intel SSD 530 boot drive (240GB)
    - Seagate Barracuda 3TB Hard Drive
    - Corsair AX760i Digital ATX Power Supply
    - Corsair Hydro Series H90 140mm High Performance Liquid CPU Cooler
Additional details:
The system was built in November 2013 and I had a similar issue in March of 2014. After several months of booting right up I started getting a B2 boot error. At that time I updated BIOS to the latest version and the problem seemed to go away. In October of 2014 it happened again (I wish I could remember what changed... possibly some windows update). I updated the drivers and updated to the latest BIOS and it seemed to work for a few weeks. It was touchy during December and now in January it happens every time I boot up. However, if I boot with the DirectKey (boots directly to BIOS), it will start in BIOS. Once I leave BIOS windows boots up. The video card seems to work fine once windows is up and running.

What I've Tried:
  • 1. I have updated BIOS (should be the latest version)
    2. I have updated all drivers (video card, processor, mobo, even the SSD drivers)
    3. I have disconnected power to the video cards and booted using the video output from the mobo (works every time)
    4. I have run a virus check and everything was clean

There are a couple of things I haven't tried. I haven't removed the video card since installing it. It's worked for over a year so I'm not sure what that could even accomplish. Since it boots every time without the video card, that must be the problem. Also, I haven't tweaked BIOS at all... I know in the Advanced Menu I can change the Primary Display to be PCIe (currently set to Auto), but I have not changed that (mostly because I don't know how that could help).

Thank you in advance for your help!

Okay, so I finally RMA'd the card, I saw a post on the sapphire forums where someone had similar issues. The good news is I ordered the card on Amazon back in November 2013 and they gave me a full refund no questions asked (took <10 minutes on the phone). Since I got a full refund I decided to get a GTX 970 instead and I'm happy with the results. Always starts on a cold boot now!

I tried this... same issue. I recently changed the PCIe Link Speed to Gen3 (previously Auto) for the video card slot. I'm not sure why that would matter, but it did start right up. The weird thing is every time I tweak something (like switching to the second PCIe slot) it works for a few days and then I get a B2 error.
