    Default GA-EP45-UD3P not recognizing video hardware

    Hi,
    I recently updated the BIOS on my GA-EP45-UD3P (v 1.6) from the FB to the FC version. It worked for the first bootup, but after a restart, no video would appear on my BFG GeForce GTX 275 OC2 Video Card. I reset the CMOS and got video back long enough to restore the FB version of the BIOS. It restarts, boots into Windows XP just fine, but after a restart I have the same issue. NO VIDEO. Not even long enough to see the BIOS menu. The computer is booting normally as I hear the logon noises.

    I've tried going back and forth between FB and FC BIOS versions, but the same issue persists. I only have this one video card so I can't swap it out with other cards, but it was working totally fine until the BIOS upgrade attempt so I know it's not a new problem with the video card. Help please :-)

    Try setting "Init First Display" to "PEG" if you have no video at POST.

    So after clearing CMOS it work for one boot and then doesn't?
    If you clear CMOS, go back to BIOS load Optimized defaults save and reboot, would you still have video? What I am trying to figure is does the problem accure only after saving DMI pool data.

    I set the video init to PEG. I've also been restarting a bunch to experiment and have found the following behavior:

    On first boot after CMOS clear, the video seems fine. After I shutdown and startup again, there is no video even at BIOS, but machine is still booting to Windows. After a hard restart from here, the POST lights on the mobo stay on (never turn off like during a normal boot), no video and doesn't boot into windows. Then, after another hard restart, video comes BACK on and the system boots normally. Totally defies logic to me.

    This cycle repeats everytime I shutdown. I have loaded optimized defaults. Also, after a successful bootup, I have to reset my dual monitors over again as if Windows has forgotten that the second monitor was ever there in the first place.

    It also seems as though video won't come on unless I have disconnected the secondary monitor. I can reconnect after I get windows boots up.

    Does this occur if you flash back to the older BIOS? If it does not, then it very well may be a BIOS issue and I would ask that you report it to Gigabyte support here if you don't mind >>

    Aha, I was unaware you were using multi monitors.

    Both NV and ATI/AMD have had a slew of problems with dual monitors including problems like yours. A mix of driver and card BIOS updates have helped but some still have problems. For example if I use HDMI fror my TV and my monitor at the same time, I get a intermittant crash, following the screens turning a funny shade of gray. According to AMD, this has been fixed.....

    If I revert to the FB version of the BIOS, I have the same exact problem. It wasn't happening before the first attempt at the BIOS upgrade however. I used @BIOS my first time and after the problems sprung up, I have been Q-Flashing from a USB drive. It seems strange that it would be a video card driver issue if the problems only began after the BIOS upgrade.

    Ahh... so it sounds like it's definitely seperate from a driver issue.

    Could you do me a favour? I know you've flashed the BIOS, but if you notice in the QFlash interface there is an option to Keep or Discard DMI data. Could you do a re-flash to th latest BIOS, or better still the latest beta (perfectly 100% safe to use, alpha's are dodgy, most betas are feature complete). This time pay particular attention to that DMI setting and make sure it discards the data. It could be that some find of glitch or corruption is messing with the stored DMI Pool data and causing the PCIE part of the board to crap out.

    The latest beta (stable) BIOS is here: http://america.giga-byte.com/FileLis...d3p_1.6_fc.exe
