I'm in need some advice and help here. I've very recently purchased my mobo, CPU, PSU, RAM and SSD. After upgrading the PC, I've updated the drivers from my pre-existing Windows 7 Pro such that they stay recent to the new hardware. Problem right now is that at random intervals I hear the "USB unplugged music" being played followed by a 3-4 second freeze on both my keyboard and mouse. It feels like the computer had a momentary lock up or something like that but recovered from it. Aprox. once a day however the computer would completely freeze up with out BSOD. The freeze up is so bad that I cannot even force the desktop to shut down by holding on to the power button. I had to turn the master power switch of in the back of the case to turn the PC down. Things I have tried so far: - switching USB sockets: front and back - updating BIOS - re-installing drivers - checking temperature (CPU max 55C, GPU max 70) You can see my complete rig in my profile specs.
