BSOD playing The Witcher 2

Hello, OhHaiKai and welcome to the forums. I will try to help you if I can. You had 3 dump files all 3 were different error codes and different causes. That is typical of a memory error. Here is what your dumps said.

[CODEBugCheck 50, {fffff8a0087d0000, 0, fffff8800457ed36, 0}
*** WARNING: Unable to verify timestamp for iusb3hub.sys
*** ERROR: Module load completed but symbols could not be loaded for iusb3hub.sys
Could not read faulting driver name
Probably caused by : iusb3hub.sys ( iusb3hub+bd36 )
Followup: MachineOwner][/CODE]

That is your Intel(R) USB 3.0 Hub Driver and can be updated from your Motherboards web site. Make sure this is your Motherboard and download from here. ASRock > Z97 Extreme4

Code:

VIDEO_TDR_FAILURE (116)
Attempt to reset the display driver and recover from timeout failed.
Arguments:
Arg1: fffffa800b80a010, Optional pointer to internal TDR recovery context (TDR_RECOVERY_CONTEXT).
Arg2: fffff88003ea7848, The pointer into responsible device driver module (e.g. owner tag).
Arg3: 0000000000000000, Optional error code (NTSTATUS) of the last failed operation.
Arg4: 0000000000000002, Optional internal context dependent data.

Code:

That is your video card driver and it means it crashed but did not recover. Please update your driver this way.

I am going to give you some links that will help you get a good clean install and not have any drivers you don't need that will conflict with other drivers. Download a WHQL driver from https://www.sevenforums.com/graphic-c...ndows-7-a.html . Once you have them downloaded, uninstall you current driver from control panel. next clean up any left over drivers from following this tutorial Drivers - Clean Left over Files after Uninstalling and select only ATI Display Drivers. After you have done that and rebooted, install the new driver, only select custom install and install only what you have to. Very few people need most of what they include. You do not need the audio/HDMI drivers as you already have that in your Motherboard drivers. Unless there is some reason you need them, the only thing you really need is the Display Driver.

Code:

MEMORY_MANAGEMENT (1a)
    # Any other values for parameter 1 must be individually examined.
Arguments:
Arg1: 0000000000005003, The subtype of the bugcheck.
Arg2: fffff70001080000
Arg3: 0000000000007b07
Arg4: 00012ee54000f60e
Debugging Details:

That is your memory which I would like you to test. It has to be run for 8 passes all at the same time to test all of the memory. That test should take 9.5-10 hours.

Please Run Memtest86+

   Information

Please download from this site only http://www.memtest.org/ in the middle of the page are the Download links, you can download the ISO.zip or the Auto USB Flash Drive installer.zip

Extract the Zip file. If you chose the ISO image, burn it to a CD using Windows Disk Image Burner or any Image burner you may have. If you downloaded the Auto USB installer, extract it, insert your USB 2.0 Flash Drive and take note of the drive letter. Run the installer, select the Flash Drive Letter, check the format box and press next. It will install memtest86+ to a flash drive. You can use either V4.20 or V5.01. Boot from your selected media. If you use V5.01 it will tell you to press certain buttons at the start, please press no buttons. The test will begin on it's own and continue to run until you stop it. It needs to run for 8 complete passes or until you receive an error. If you receive an error, stop the test. Even 1 error is a fail. Each pass tests a different part of the ram and each of the 10 tests in each pass tests something different. It takes a minimum of 8 passes to completely test the ram, more passes are better. It is quite a long test and will take several hours depending on how much ram you have. Due to the time length it is best to run overnight. If you have any questions, please do not hesitate to ask

Take 1 stick and run it in each Motherboard dim slot. If it passes, move it to the next slot and so on, then switch sticks and do the same. What we are looking for is whether the problem is bad ram or a bad dim slot on the board. So, you need to keep track of which stick and what it did in each slot. It is most likely the ram, but I have had boards before where the problem was the board and not the ram. You can RMA the ram to Corsair, they have a lifetime warranty, but you should send both sticks in and get a kit in return. Kits are tested to run well together. Individual sticks are not.

When you are testing the sticks, a bad ram module should fail in every slot. If both sticks were to pass in slot 1,2 and 4 but both failed in slot 3, it would be a bad motherboard dim slot. Do you understand? If you have any questions, please ask.

Sure, any time. If you have questions, don't hesitate to ask.
