LoLclient.exe crash

I posted this in "Help and Support" ( http://boards.na.leagueoflegends.com/en/c/help-support/s07oEExk-lolclient-crash-does-not-actually-affect-gameplay-though ) but have not gotten any feedback yet, so i'll ask here (as it happens every time i run the client).

From the time I log in to LoL i have approximately 20 minutes before the client crashes on me, whether i'm just leaving it idle in the background, or active in chat/market/masteries/etc. If i start a game, then within 5-10 minutes of playing i'll recieve the same notification, yet it does not affect the actual game itself. However after the game it won't load up the client window with the final game results, just goes straight to the desktop.

This crash is not giving me an error number to search for. One suggestion i received from a twitch user was to disable IPHelper. I've done so, and it had no effect on the crash itself. the only information I get is "LoLclient.exe has crashed" with the option of "close the program" and "close the program and search online for a solution" (which doesn't even run a search, it just closes the window and laughs at me)

there is an option for more info, and the following is what is displayed....

Problem signature: Problem Event Name: APPCRASH Application Name: LolClient.exe Application Version: 0.0.0.0 Application Timestamp: 515663e0 Fault Module Name: ole32.dll Fault Module Version: 6.1.7601.17514 Fault Module Timestamp: 4ce7b96f Exception Code: c0000005 Exception Offset: 0004860e OS Version: 6.1.7601.2.1.0.768.3 Locale ID: 1033 Additional Information 1: a7aa Additional Information 2: a7aa91f17ea749d42a4de3b390fa5b3d Additional Information 3: a7aa Additional Information 4: a7aa91f17ea749d42a4de3b390fa5b3d

is there anything I can do to prevent this so i can play more than one game without having to re-run the patcher? (and, ya know, carry on a conversation with friends)
