    Hello, Trondheim I'll try to help you as much as I can. A TDR error (Time Delay and Response) is an error that occurs in a lot of Laptops with switchable Graphics. Your Laptop uses the Intel graphics on less demanding work and switches to the AMD graphics card on more Demanding work. Almost all OEMs (HP, Dell Compaq) adapt their switchable graphics to work differently so they have to edit the drivers to make it happen the way they set the Laptop up to work. The problem comes in when the laptop switches from one to the other. It does not do it fast enough, so Windows assumes that there has been a graphics failure and that is when you get a BSOD. That is what a TDR error is. We have worked numerous cases of this here and have found no solution for it, other than to disable the Dedicated Graphics Card (AMD in your case). That is the only way we have found to solve the problem. I have a laptop with Optimus technology, which is Nvidia;s implementation of what you have. I had to do the same thing. I only offer this as an explanation so you will understand what is happening.

    If you will go into your BIOS and see if you can find a way to disable the switchable graphics, that is the best way to do it. Otherwise if you will go to device manager, find your AMD Card under display adapters, right click it and select disable. it should solve the problem. I realize this is not the best solution to solve this problem as far as you are concerned, but it is usually the only one that I have found that works. Please try that and get back with us to let us know whether it has worked for you.

    If you have any questions, please feel free to ask, I don't mind at all.

    Thank you for your help essenbe.

    Actually I have already tried to disable the AMD graphics. The thing is that (as I wrote before) it disables many features I use very often, standby to name one of them.
    However, are you saying I could disable the switchable graphics in the BIOS settings, and thanks to that being able to run with only one of the two cards?

    If such alternative is possible, I guess I could use AMD graphics only. I'm not quite a expert in this matter, maybe you can answer me.

    Thank you

    But I am still wondering... I restored the laptop this morning to Factory settings. Howcome I can't even start windows now? Every time I try to do so, a BSOD comes up before the logon screen. In my sense, that's weird. And it reveals the uselessness of this procedure in such case.

    Unfortunately, I am not an expert either. I don't know if your bios has that option and I am not sure that is an option with AMD. If it were my Laptop, I would try it, but I suspect it would not work. But, please understand this first. Unless I am wrong, AMD graphics are set up to where all graphics run through the CPU which is where the on board graphics are. So, therefore, by turning off the on board graphics, you may be turning off all graphics. That being the case, I would be sure I knew how to reset CMOS, just in case.

    Your drivers are crashing before Windows starts. When Windows starts is when the drivers begin to load.

    Sorry about that but what's CMOS?

    About what you said before, I noticed that when I disable the AMD graphics I disable all graphics because when I do, Intel graphics starts to malfunction.
    I will check later in the morning if I can change the settings in the BIOS.

    I did not know that the drivers were crashing before Windows starts. Thanks for that information. I will come back to you and give you the final feedback about this issue.

    Thank you for your help, it was very appreciated. :)

    Hello essenbe,

    I tried dealing with hp support, but there is no way for Pavilion g6 (and maybe g7) owners to change the switchable graphics settings from dynamic to fixed. Because that would be the solution : the system would run with the AMD device as default device. I checked the BIOS a few minutes ago, and there is no such option.

    I disabled the Intel graphics via device manager, and of course the AMD card was disabled in the same time. As a result, let's say I will not use my laptop for games or videos ever again.

    Thank you a lot and I hope no one will have to face this issue !

    This is a constant issue with a great number of Laptops with switchable graphics, both AMD and Nvidia. Fortunately, sometimes Nvidia are a little easier to deal with. But, your solution is the only solution I know of.

    The idea of switchable graphics is a good one. You do not have the drain on the battery when it is not needed, but when the dedicated card is needed you have it. The implementation is the problem. Almost all OEM Manufacturers do it differently, which means that the drivers have to be specially coded to work the way the OEMs implemented switchable graphics. I'm sorry I can't give you a better resolution for your problem, but rest assured it is a very common problem and this is the only resolution we have been able to find. It is not specifically an HP problem. All OEMs suffer the exact same problem you do.
