Random freezing

[JeanPrado]

I have a HD 3000 graphics card with i5-2500K and a GA-B75M-D3H motherboard, with successfully installed and almost 100& working 10.11 El Capitan installation with Clover bootloader.

However, 3 or 4 times a day my system freezes and I have to restart it manually. The funny thing is, even the seconds counter stops but the music keeps playing. What could possibly be causing this?

My IOReg is attached, but I don't think it'll be enough. Is there any other file that I have to attach?

No one? It's still happening and I can't figure out why. It's very random.

Six months later and this is still happening. Can anyone help me?

Do you have any add-in cards, like Firewire?

Are you using approved memory for your motherboard? If you're not then its could be the source of the problem. I had random reboots due to unapproved memory modules until I had the memory replaced recently.
