And secondly i have to say that i had before Windows 8 Pro X64 and i got "freezes" almost in every windows startup then i had to restart it manually to get it working, also in the desktop, sometimes it crashed and sometimes it shuts down by itself in a few seconds after powering on etc..., so i thought it has to do something with the RAM Memory and i got it replaced with a new stick and i tested it with the Memtest86 with 3 pases and i didn't get any error, also checked the hard drives for bad sectors but they are healthy as well, so i told to a service man that i'm still getting freezes and crashes and he told me to install the Windows 7 because Win8 is still not completed and has some bad issues so i got installed Windows 7 with all needed drivers and windows updates, it was fine until tomorrow and then i went in the same situation and then i changed the kingston ram with corsair still the same things happen again, so the only thing that i think is causing these issues is motherboard but still not sure and i need some advices from you, Thanks!
