    Someone went through this process within the last month or two. However, I can't remember which thread.

    You can't use SRS but once you've got the contents of the recovery partition then you can create something bootable. Sorry I can't be of more help.

    You should have two Samsung Recovery partitions (at the end of the drive) and one Windows RE Tools partition (at the beginning of the drive). See this post for details.

    The large Samsung Recovery partition (at the end) contains the factory image, while the small (just before) contains the software needed to F4 boot Recovery.

    If all partitions seem to be present (and non-empty) but neither F4 nor the Samsung Recovery Windows App work, then most likely the prior owner (or dealer) backed up and restored the disk using a 3rd party partition imaging tool - which destroys the F4 link that tells Recovery where to look for it's stuff. And unfortunately it is very hard to repair.

    The process requires tricking Recovery to boot, then use that to create a Bootable Factory Image USB backup (which it sounds like you were all ready to create), then use that USB to re-image the entire drive. This post contains suggestions to try, but not all succeed in booting Recovery once the F4 link is gone.

    As I wrote in my previous response, you could just clone the disk using Samsung Data Migration, then delete the Recovery partitions from the SSD (because they won't work anyway) and use the Windows installation.

    I would also contact Samsung and request a Recovery DVD. They may give you that or insist that you send it in for re-imaging.

    - pull the power cord and put it back again

    This helped me, BF4 running OK with this "hack". Every time map reload i need to do this. I hate AMD graphic cards for long time because of lot of bugs.

    Hi,

    I cannot recall how many times I wiped and reinstalled the drivers, following the instructions from leshcatlabs (UnifL Manual), using DriverFusion on both Intel and AMD drivers and cumulatively in Windows Standard and then in Safe Mode...but after all, nothing really changed for the better.

    As the problem did not occur in Windows 8, I suspect it's a software or BIOS problem. In the WoT hangar, for example, sometimes the performance suddenly drops when opening a dialog window that just displays some simple text info (the hangar itself is a 3D display). In this case, the click or the switching to the dialog seems to be the trigger. In battles, there are also boxes with team infos and the like, and sometimes, everything runs fine until invoking one of them. Checking with HWInfo64, the AMD GPU still seems runs at full speed with fans running, too. I very much suspect that the AMD Enduro mechanism gets confused somehow and stops delegating the rendering to the AMD GPU, but I can't tell for sure. Apart from HWInfo64, I didn't find a tool to check the AMD GPU at all, and all info I know of is provided by the ATI sensors there.

    In any case, I don't think it's a hardware problem, and I never ever overclocked the GPU, so that cannot be the cause :)

    HTH,
    -- Chris.

    Is this problem also in Windows 8? Because i saw this problem first time in Windows 8.1. Or maybe there is a problem with new BIOS because i made update in Win 8.1.

    I'm on Win 8 and I have this issue, so it's not Win 8.1 related. :(

    That makes sense. Thanks so much! I will try Samsung Data Migration.

    Is there a list of startup programs to disable for faster boot times?

    FYI - As is this laptop is a BEAST!!! No color issues...no speed issues...or the other things others have complained about. Upgraded to 8.1 without a hitch and this thing has just been a pleasure to work on...just want to tweak it a lil for optimum performance.

    Anyone else has any suggestions?

    I also changed my wireless card to a 7260 AC 2x2 two days ago. Its a little better than the 6235 but its still not as good as the 5100 I had in my last notebook. I still get drops in download speed every few minutes. But its totally usable for day to day surfing the web. From what I can tell, I get better results when I connect to 5GHz networks rather than to 2.4GHz.(I am connecting to an 802.11n network)

    I also noticed that my bluetooth mouse lost connection every few minutes. Luckiely I could fix that by telling my computer that its not allowed to turn bluetooth of to save power.

    Please tell my about your experience.
