random system freezes OS X 10.10.3

[HennoeR]

Hello,

for the last few months my system freezes sometimes and I have to hard restart it. Until today I thought the crashes were caused by me accessing any kinds of USB connections (turn on the printer, plug in a flash drive ...) (see my previous thread: here), but e few moments ago the same crash happened without any apparent reason.

If you have an idea or even a solution please let me know


Also I can post the console entries

Reloading my system using Clover fixed all my freeze issues. You might want to think about re-loading Yosemite with Clover

Yeah, I also thought about it. But I have absolutely no knowledge about Clover and I'm afraid to break something if I do it wrong. Also how do I upgrade to Clover if I'm already using Chimera?

So, I have the same freezes for a short time. The solution for me is change EFI bios (modify some "auto" do "enable") and is aways start a system with -v -f...
Just Try.

Good luck
