Unpredictable crashes on desktop

This is my first post and so I hope it is in the right section and if not hopefully a moderator can move it. I have been having some issues with my desktop since I initially built it last july, while most have been insignificant I have had one glaring issue. At times when gaming the computer will crash to a randomly colored screen( not bsod). The computer will be fully unresponsive and requires a hard reset to turn it back on. This only occurs when playing games; however, this has a caveat. It crashes during league of legends primarily, occasionally during fifa 13, but never does during higher stress games like battlefield 3, running it on max settings. The crash would generally be accompanied by a whirring sound, not from the tower itself but through the audio, which I suspect was the last fragment of audio just on a very frequent short loop repeat since it was the lat sound input. The action center would show that there was a display error when reviewing the crash. Sometimes the crash would be after a few minutes of play, sometimes after hours. It could crash, I could power it off and let it sit for a short while, power back on, boot up league to play, and within a couple minutes it crash. So time does not seem to be a factor in when it crashes(though it did seem to happen more often early or that it would be a decent amount of time before it would happen. So either <5min or>1 hour)

Initially I was confounded and could not determine the problem, using programs to monitor the components my cpu temperature was never exceeding 42 degrees, ruling out over heating. The voltage stayed steady and seemed to not be experiencing any issues. I ran stress tests on the graphics card itself running it at 90% max capacity for two hours without even a hiccup. At this point the logical response would of course be some form of driver issue and it turned out it was. I had thought the drivers were up to date, using the disc that came with it but silly me, I of course needed to go to the site. Once I updated the drivers using the site,this problem completely disappeared. I continued to vigilantly check to make sure I had the newest drivers to avoid a repeat of this issue. A month of no crash no problem experience, but that did not last.

A month after I properly updated the drivers the problem has reappeared. My drivers for the video card are the most up to date available. The problem now solely appears when playing league of legends where before it would also sometimes occur when playing fifa 13. Other notable differences are that now windows does not report a display error, only reporting an unexpected shutdown, from the hard reset. Also where the crash would generally be accompanied by some form of noise with it(loud buzzing audio), the computer now solely crashes to a random color and is unresponsive. I have done clean installs of the latest drivers in case they did not install properly. I have done a clean install of league of legends to see if the issue was some weird client to gpu glitch. I then did a system restore to the day before the crashes began along with another clean install of League and gpu drivers. After the restore I managed to play 2 full games without a crash, after that it began crashing after a few minutes of play. I have probably played 15 hours of other games without crash in the last several days, but in league it is a guaranteed crash. Also have ran malware bytes to scan for anything malicious and used cc cleaner to clean up the computer some.

This leaves me pretty much out of ideas as to what to do or what could be the cause. And any help would be so very appreciated.

I highly recommend a memory test using HCI Memtest. Read the instructions but run one instance per core by setting the Affinity, and test a total of 90% of your RAM. For 8GB RAM and an octa-core, that would be 900mb per instance. Run it for at least 500% coverage, up to 1000%: http://hcidesign.com/memtest/
