BSOD playing Diablo 3 and Dota 2

[odditie]

OS is Windows 7 Ultimate x64.
This is the original OS on the system.
It is a full retail version.

The system is only 4 months old (built early this year).
The Windows 7 installation is also 4 months old.

The problem only seems to occur when playing games. Sometimes it happens soon after starting a game, while other times I can play for hours without getting a BSOD.

Lot of 0x101 crashes. These cannot be debugged without access to a kernel dump (that big ole MEMORY.DMP located in your Windows directory). These can commonly be caused by CPU issues, but software can also be attributed to it. I did see a couple of 0x124 bugchecks (WHEA errors), but there's no crashdump associated with em so I can't tell exactly what hardware error it's reporting about. I could check the MCi_Status info, but I'm not gonna even bother at the moment, given that it means whipping out the Intel CPU manual and comparing bit flags. Regardless, having the 0x124 crashes mingled in with the 0x101 has me believe we're dealing with hardware problems here.

Just to make absolutely sure, though, you should first update your BIOS, as well as all drivers related to your motherboard components. Do not install USB "drivers", and if you have already, uninstall. In addition, if you have any motherboard software like OCing tools and whatnot, uninstall all of them. They are extremely buggy, gimmicky, and I've seen them trigger hardware failure like the 0x124 bugchecks.

Next are a few hardware checks. These aren't 100% guaranteed to find a problem, but they're far better than nothing. Run them in order listed. Here they are:

RAM: Memtest86+ - 7+ passes
CPU: Prime95 - Torture Test; Large FFTs; overnight (9+ hours)
GPU: MemtestCL - Run twice (if any of the tests work on your GPU; ATI cards will need to install the ATI APP SDK as it requires OpenCL)
Drives: Seatools - All basic tests aside from the Fix all or the advanced ones.

All of these (excluding MemtestCL) are included in the UBCD if you prefer a Live CD environment (which is the best environment to test hardware on). Note that Prime95 currently does not work on the latest version of UBCD. Also, please provide us temps/voltages using HWInfo with Sensors only option checked. Log two 30-minute instances: one for idle, and one for high load. If you can get the system to crash during high load logging, that's even better.

I uninstalled the usb driver for my motherboard. I am in the process of updating the BIOS for it and grabbing some of the other motherboard updates listed on the manufacturer's website.

I will try to have a post in a few days that covers all of those tests that you gave me to run. I tried running memtest in the past and everything seemed to come out alright, but I will run it again. I also ran prime95 in the past and on the large FFTs setting it usually crashed within a few minutes (I will also try running this again). The other tests I have never run before, but I will try to get you results within the next few days.

With the HWInfo test, I know you said you wanted two readings (one while idle and one under a high load). Should the high load reading be done while I'm playing one of the games my computer BSODs on or during prime95 since that has caused it to crash before?

If Prime95 is crashing your system, you got hardware problems, which most likely is of the dreaded Trio of Trouble: CPU, Motherboard, or PSU, with CPU being most suspect. Given that you're having 0x101 bugchecks and the occasional 0x124, I wouldn't doubt your CPU is faulty.
