Hi,
both dump files were of the same bugcheck although probable causes were different. This bugcheck can be caused by:
Cause There are generally three different causes for this bug check:
- A driver has inadvertently, or deliberately, modified critical kernel code or data. Microsoft Windows Server 2003 with Service Pack 1 (SP1) and later versions of Windows for x64-based computers do not allow the kernel to be patched except through authorized Microsoft-originated hot patches. For more information, see Patching Policy for x64-based Systems.
- A developer attempted to set a normal kernel breakpoint using a kernel debugger that was not attached when the system was started. Normal breakpoints (bp) can only be set if the debugger is attached at start time. Processor breakpoints (ba) can be set at any time.
- A hardware corruption occurred. For example, the kernel code or data could have been stored in memory that failed.
In your case you probably have a driver causing these issues or a possible hardware issue.
Checking through the driver stack your drivers look in pretty good shape apart from:
SaiK0CFA.sys Tue Jul 20 17:26:29 2010: Possibly a Saitek mouse or keyboard? 2010 is a little old for Windows 8.1 (windows 8.1 hates old drivers) and I would try and update whichever device it is. ( I now see it's a Cyborg RAT 9 latest driver is 2012 version, I think):
http://www.cyborggaming.com/download.htm lvuvc64.sys Tue Oct 23 03:12:08 2012: Logitech USB Video Class Driver (WebCam) check for update:
http://www.logitech.com/index.cfm/support_downloads/downloads/&cl=us,en Check you haven't got any corruption in Windows by the system file checker. Open an admin command prompt and type:
sfc /scannow
Press enter and await results.
Check your GPU memory is ok by running this test:
http://mikelab.kiev.ua/index_en.php?page=PROGRAMS/vmt_en If after making the above changes you still get the bsod then you need to test your RAM.
Windows does have it's own memory testing app but it can often miss errors and the best app for the job is Memtest86. The latest version of which can be found here:
http://www.memtest.org/ To run Memtest86 you need to either burn a copy of it to disk or use a USB stick. If you look down the page you'll eventually find the latest version and it's associated downloads. If your burning to disk choose the pre-compiled iso zip. If your using a USB method then the corresponding download is the auto installer for a USB stick.
Once you have Memtest86 on the media you selected you'll then need to enter your bios and change the boot order so that the machine will boot from either the disk or stick you have Memtest86 on.
Try and run the test overnight if possible unless it becomes clear that there is a issue. If there is a problem with the RAM you'll see the errors pop up in red so you can't miss them.
Can you post the make and model of your PSU please.
Post any new dump files.
