So, I've had this specific hardware setup for about four months now and haven't had any problems with any game or program, up until the beginning of this week, where I was playing Minecraft, and I suddenly got blue screened. I don't remember the error, because it didn't stay on the screen for long enough. I figured maybe it was a one time fluke, because I had done very rigorous testing with much more intensive programs, such as HyperPi, Sony Vegas rendering 1080p, OCCT, FurMark, ect... to get a feel for my MAX temps and such, and they're all completely fine. Sony Vegas I actually use quite a bit for video rendering, and it pegs all 8 of the CPU cores at 95% or so, giving it a max temp of 71 Celsius.

Keep in mind that I run all games capped at 60 FPS, so my hardware doesn't run at max at any time, like it was when it got tested with the aforementioned programs. Well, a couple days later, I get blue screened again while playing Guild Wars 2. GW2 and Minecraft don't even use more than, like, two cores on the CPU, and Minecraft uses almost none of the GPU, while GW2 was using admittedly most of it on the ultra settings.

However, the third time I got blue screened was today, and while I was running GW2 at the lowest possible settings, because I was getting prepared for a huge boss fight with tons of players which crashes the game at ultra settings. The CPU and GPU were getting no where close to strenuous usage, so I can't help but wonder what would suddenly cause these almost random blue screens, when much more vigorous testing programs and games will run completely fine on it and have been doing so for several months of almost 24/7 use.

I have a Windows minidump file, but I don't know how to determine what's causing the blue screen in my games from reading it. Could anyone help with deciphering what this file means and get me started on a path to figure out where in Windows the ISSUE is coming from?

Minidump File: https://www.dropbox.com/s/hogj3d18sy59gfi/020615-4836-01.dmp?dl=1Do you overclocked the CPU processor during this time? It seems its the report found on the dump file while running GW. Quote from: jason2074 on February 06, 2015, 10:20:04 PM

Do you overclocked the CPU processor during this time? It seems its the report found on the dump file while running GW.

The processor has been set at the same speed and voltage listed at the top of the post since four months ago. I haven't changed it at all from that stable overclock. The processor would be 4.0 Ghz default base and uncore - 4.4 Ghz default core turbo, though.The first thing you need to do is download and install both a GOOD anti virus app and MalwareBytes. Then run full scans with both. Let's see what happens after that. Quote from: Allan on February 07, 2015, 06:37:52 AM

I only downloaded MalwareBytes, because I'd rather have a recommendation of an anti-virus than just search for some random one you guys might not agree with.
Here's the threat scan log: https://www.dropbox.com/s/lgbvhuis5myabov/MalwareBytesScanLog.txt?dl=1I would suggest MicroSoft Security Essentials or Comodo.

Remember to only install one antivirus!
 
1) Avast! Home Edition
2) AVG Free Edition
3) Avira AntiVir Personal
4) MicroSoft Security Essentials   All versions and all languages.
5) Comodo Antivirus (Uncheck during installation "Install Comodo SafeSurf..", Make Comodo my default search provider" and "Make Comodo Search my homepage" if you choose this one)

It is strongly recommended that you run only one antivirus program at a time. Having more than one antivirus program active in memory uses additional resources and can result in program conflicts and false virus alerts. If you choose to install more than one antivirus program on your computer, then only one of them should be active in memory at a time.All of the above are excellent free choices. If you want to pay for a product, I'm a BIG fan of KasperskyAlright. So Microsoft Security Essentials isn't reporting anything to me as far as malicious activity, so where do I go from here to figure out the source causing these blue screens? Does the minidump file in my first post point out anything to you guys as far as a Windows service or specific hardware fault that made it blue screen during my game?The dump file is gibberish when I try to read it. You can post the contents if you like. More important, please do the following

Go to System Properties - Advanced - Startup & Recovery Options and UNcheck "automatically restart". Now reboot. Next time the system gets a bsod it will remain on the screen. Please copy and post the entire contents of that screen in this thread. Quote from: Allan on February 07, 2015, 03:13:41 PM

Done and will do. Though, with its unpredictability, it may be a few days or more before I can get a capture of it.Any Yellow !!'s in Device Manager ? ? Quote from: patio on February 07, 2015, 06:38:42 PM

Nah. Everything is all good in the device manager. I've just disabled a sound driver from NVIDIA, because I only usually use the sound from my motherboard ports. Quote

Go back to default or stable clock and voltage output then check the difference. Quote from: jason2074 on February 07, 2015, 08:33:33 PM

I was hoping it'd be possible to tell from the dump, or when the blue screen comes up again and I get a capture of it, if it's any specific hardware OC, because the CPU core isn't the only thing overclocked. There's the uncore also at 4.5 Ghz, the 1866 Mhz memory is running over Intel's supported range for the CPU, which is listed at 1600 Mhz, and the command rate timing has been lowered by 1 from original spec. It could also just be a borked service running from Windows, so the unpredictable NATURE of the blue screen means I may not get conclusive evidence just from setting some things or one thing to default, because it may not happen by coincidence, or may be only a specific combination of any of these settings in BIOS together, instead of alone.

I'll wait for the next blue screen so I can get a capture of it, then if it can't be determined from that, I'll start setting defaults. The only question would be what to start with, or if it should be some sort of combination, and how long I need to wait for no blue screen to occur before deciding that isn't the problem.The minidumpfile log
