Mac restarts while playing a game

Question

Hello everyone,I have had my iMac for a little over a year now. I used to have no problems at all. Then, I believe since Mavericks, my system started to crash every now and then, mostly while playing the videogame League of Legends. One day when this happened again, a hardware issue appeared and my Logic board/motherboard was replaced. Now, I was playing League of Legends again and my Mac crashed and rebooted. I know there are many problems with the Mac client for this game, but I&#x27;m still concerned. The staff at the service point reassured me I could not have caused the hardware issue myself, but I have to ask... Can I break my hardware by playing a videogame?

The graphics processor is faulty and will have to be replaced.Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.Print the first page of the panic report and bring it with you.Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn&#x27;t fully functional — ask if you need guidance.  If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.Keeping your confidential data secure during hardware repairApple also recommends that you deauthorize a device in the iTunes Store before having it serviced.*An SSD doesn&#x27;t need to be zeroed.

It would appear that the game is compatible with Mavericks:http://roaringapps.com/app/league-of-legendsMake sure you are using the same version stated to be compatible.The hardware may already be marginal.   RAM if not installed by Apple has to be known to be compatible with Late 2012 iMac, and not just say a timing spec or pin number, not be ValueRAM, and have a lifetime warranty.  http://www.crucial.com/ and http://www.macsales.com/ can ensure you get the right RAM.

If you have more than one user account, you must be logged in as an administrator to carry out these instructions.   Launch the Console application in any of the following ways:☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.☞ Open LaunchPad. Click Utilities, then Console in the icon grid.    Select the most recent panic report (with a name that begins with "Kernel" and ends in ".panic") under the heading System Diagnostic Reports on the left. If you don&#x27;t see that heading, select   View ▹ Show Log Listfrom the menu bar. Post the entire contents of the report — the text, please, not a screenshot. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don&#x27;t post any other kind of diagnostic report, such as a hang report.

Make sure the power plug is correctly in the machine:http://support.apple.com/kb/TA27217If it is, then you likely have a power supply issue with the machine.

Seorin · Answer

I always keep my system and my game client up-to-date.My RAM is the original RAM.I&#x27;m not sure what you mean by marginal.

a brody · Answer

Original RAM can go bad, and is sometimes detectable by the built-in hardware test.Boot with the &#x27;D&#x27; key and run it to see if it is detectable.

Seorin · Answer

The test came back clear.

Seorin · Answer

Are you absolutely sure about this? I just had my motherboard replaced. How come they did not identify this problem and replaced that too?

Linc Davis · Answer

The GPU is separate from the logic board. I can&#x27;t tell you why somebody else did or did not do something.

Seorin · Answer

Thank you.
