    Default gdrv.sys = BSOD in windows 7

    not sure which gigabyte driver /program installs this but it crashes in windows 7 x64 at least twice a day.

    It was just rebooting the system , so I turned off blue screen auto-reboot
    and gdrv.sys was the offending file all 3 times.

    As if it's not hard enough keeping everything stable while trying to Overclock, Now you have to hunt down and disable (I just renamed it) gigabyte files .

    Just incase anyone else is having this problem the file is found in the windows folder, just rename it gdrv.sy_ and you should be fine

    gdrv.sys is a component of Dynamic Energy Saver Advanced. To be honest it's not really a good idea to be using it while trying to overclock. The last thing you want is DESA shutting down power phases on an overclocked CPU. The better course of action would be to restore the file to its original name and then uninstall DESA.

    All I installed off the gigabyte disk was easytune 6
    theirs no listing for Dynamic Energy Saver Advanced in add and remove programs

    Then it's possible that the file is included in ET6 too.

    The version of ET6 on the motherboard CD is actually pretty old. The latest version is on the gigabyte web site and may not exhibit this issue with gdrv.sys. As with all motherboard CD's, the utilities it contains are seldom updated after the first pressing unfortunately. For the UD3 series that's at least a year and a half. For the latest version of ET6 go here: GIGABYTE - Support&Download - Motherboard - Utility

    As the motherboard CD and the board itself were both released well before Windows 7 was, it's not really Gigabytes fault it has caused problems. Strange things can happen when software not intended for a certain OS is run. Usually it works OK with Windows 7, as long as it works with Vista. ET6 accesses some pretty low level settings and directly polls the BIOS, meaning you really need a version designed for the exact OS you're using at the time.

    ok thanks for your help :)

    Edit: downloaded the new version and installed it after uninstalling the old one and rebooting.
    Guess what, gdrv.sys has not changed ..the file that was installed has the same time stamp and digital sig (‎Thursday, ‎March ‎12, ‎2009 10:27:06 PM - Product version 5.2.3790.1830) as the one I renamed that has been crashing the system.

    So now what ..rename the new one also ? ..Or just wait for the next BSOD ?

    anyone else know why that file is installed by easytune6 and crashes when the pc goes into standby?

    Maybe your system is unstable, if it is not 100% stable then S3 sleep can cause many random issues.

    Are you SURE you do not have DES installed? I ask because I have only easytune installed and I do not have Gdrv.sys on my system at all

    Default Re: gdrv.sys = BSOD in windows 7

    I just this second installed |ET6 from my Mobo CD and can confirm that gdrv.sys is not present on my machine. I'm running Windows 7 too. Absolutly everything out there info wise states that DESA is the source of the file. Scanning the archive for the DESA program confirms that it's present. I haven't installed it, not a good idea on an OC'd system.

    No you don't wait for another BSOD.. uninstall what ever uses the file or get rid of it. Did you even check to see if ET6 functions without it? My system doesn't have the file and ET works fine.

    Here is a screen shot of a search for the .sys file (not found and a pic of ET6 working ok. I'm not saying you're a liar and the .sys wasn't installed for you. If you say it was then it was. Just wanted to confirm that it is not a needed file for ET6 to work. I've used E|T just now to change FSB, voltages etc and fan speeds. All the features and all monitoring tools work perfectly, CPU info matches CPU-Z etc. You can go ahead and delete this file if it's causing issues.



    Standby (S3) is broken for many people on the UD3 series of boards and it's possible this has nothing to do with that file.

    You haven't given us the BSOD stop error, or informed us if it gives a stop error (error codes not only tell us the source of the problem but sometimes why it happened). Have you also looked in the event log to see what happens at the time of the BSOD? Auto restart can be disabled in the advanced config menu. The same can be done with sleep. Note the approx time, pop the PC into sleep, if it fails to resume or crashes, restart and then look in the event log. You are most welcome to post the contents (only the relevant bits, logs can be long) for Lsd etc to see.

    Software compatibility issues are unfortunately part of owning a PC, they can be unexplained and happen for no apparent reason. It's a miracle to be honest that software works as well as it does woth such a mix of different components going into each PC and nothing to rely upon but semi-loose industry standards.

    Here's a shot of all the software I have installed. If I have DES installed i don't know what it looks like.

    here's the files that I renamed ..the second one was created on the second install of easytune6.

    I didn't write down the stop codes because the blue screen told what the offending file was ..pretty easy to figure out what to do after that
