I upgraded my system for:

Gigabyte B75-D3V
Intel i5 3570

I have randomly system freeze. All USB device randomly switch off (no light)
There is no error message, It seems the computer go an, but I do not have any kind of USB devices. (mouse, keyboard etc.) I can just restart the system to bring it back.
I have several USB devices: mouse, keyboard, external sound card, webcam.
What I tried:
BIOS update, PSU replace, mouse replace, I have bought an USB hub with external power source, re install the system (clean and full), switch off power saving of USB devices. No use. I things come back randomly within 1 min to 2 days.

Please help to solve this problem

Thanks.

I hope I have found the solution. I disassemble the PC and rebuild again. I am not 100% sure but may be one of the SATA cable was not corecly connected to the HDD. It was loose. Since then, 2 weeks left without problem.
