Mac's Kernel panic at some apps

Since upgrading to Sierra, my mac has kernel panics at some apps like Microsoft Powerpoint, games or when playing a video. I downgraded back to snow leopard, but it still has the panics.

Here is content of one of my panic reports taking from Snow Leopard logs:

Is it a RAM related problem? I swapped the RAMs with a another pair of RAMs, but it did not help. I still have the crash. I have started the extended Apple Hardware Test, but so far it has not found any hardware issues. I'll report back if it comes across a hardware malfunctioning.

Any ideas will be greatly appreciated.

I had this exact same problem with my mid-2010 Macbook Pro, for me it was caused by a capacitor on the logic board that had broken and shorted. I replaced mine a couple of days ago and haven't had the problem again since. If you have also noticed that you have a lower than normal battery life then this is most likely the cause. I think it is supposed to be using in powering your GPU's RAM which would make sense why it says that ram is a problem. Until I fixed this problem I used a program called gfxCardStatus (https://gfx.io/) which allows you to force the use of intergrated graphics in a little drop down in the top right of your screen. It will mean that you can't really game with your laptop but it should stop kernel panics.

Thanks for replying. Did you replace the capacitor yourself? Could you let me know which capacitor?

Do you mean the one circled in the following picture:

Thanks.

So very sorry that I forgot to reply. I did replace the capacitor by myself and yes it is the one circled.

Does it need high-tech tools for doing so? It must be very tiny.

I managed to do this myself with a soldering iron that I already had and some fine soldering tips. If you are going to do this yourself; make sure that you put the capacitor on the correct way and watching this video should help with any other questions you may have:

If you need anything else please feel free to ask, also below is a link to buy the capacitor if you do decide to do it yourself.

Thank you so much for your help, but at the moment the software solution I mentioned in my comment above does the trick. Maybe I'll try the harder alternative if absolutely have to.

Kernel panicks could be many things.

Bad RAM or ICs are a last resort and very rarely the issue.

To start, I would try checking the hard drive.

Thanks for your answer. But I am sure the capacitor mentioned in the above post is the problem. Fortunately, there is a makeshift software solution for this problem:
