Hi

Also i have noticed that my mouse and keyboard have power when the pc freeze but if i unplug them and plug them in no power ,are like dead.i tried all usb hubs after freeze and no powew is going to keyboard and mouse

My system is

i boot the system from ssd.
other hardware pluged in is an hp webcam 2300,a natec keyboard and logitech mx518 mouse and a tp link wifi reciever.

some extra information that may cause the freeze is that the second drive 465gb i took it from my laptop that is not working because of his gpu and installed it 3 weeks after i bought the system. In the begining i didnt have problems but also the freezes come randomly in 5 months my computer freeze 20 times max.
I had also put a second fun in the side of the box.
As you can see my temp are very low,
also i ckecked for malware with malware bytes and avg and for rookits in drivers and i get no bad results, also i checked my ram with memory diag and nothing found.
Today was the last freeze and happend while i was plugging and unplugging the mouse and keyboard because it was a mess with all that wires,. The other times the freeze happened randomly whlle i was listening to music or searcing the web.so i dont thing the plug unplug caused the freeze today
One time i noticed that after i restarted the system freezed again after a few minutes.
Please help me the system is 5 months old, thanks a lot and sorry for my bad english
