Minecraft frezees whole computer after some time

When i play Modded Minecraft (All the Mods 8) my whole computer freezes. I then have to power of the PC using the power button.

I use the PolyMC luancher. And my memory usage is usually at 40-50%

  1. Turn off all the mods
  2. Check how MC behaves (probably it will behave nice, if not, try other launcher)
  3. Turn one mod - check behavior
  4. Continue turning on other mods and checking, till you will find one, which creates a problem

Once you found mod which causes problem, report to mod createor

Well i started with the FTB launcher but switched to PolyMC to fix the freezing. And testing evry mod would take around 275 hours.
