New Custom Build Computer Hard Freezes

Hey guys, I have a PC that was custom built with all new hardware, and it has hard freezes requiring a cold boot. It happens anywhere from once a month to a couple times a day
These freezes occur while doing anything from watching a movie, browsing the web, or when it's just sitting idly.

I replaced the PSU, flashed the Bios, reinstalled windows, changed the power settings, updated drivers, and re-sat the ram with no change!

Windows event viewer doesn't show anything that related to the crash except "previous system shutdown was unexpected".

After running stress, cpu, and memtest all came up fine.

Since all the hardware is all new not sure what to switch out next, if I should reinstall windows 7 again or change something in the bios.



I'm using a
Intel i7 3770k,
Intel graphics 4000,
Asus H61M-A Motherboard,
1 Crucial DDR3 Ram 8GB
Samsung Evo 840 SSD as primary drive,
Seagate 1TB HDD
Corsair 550 watt PSU

Any help is appreciated!
 
Nice little system... Make sure that the boot SSD drive is on a SATA3 port configured AHCI in the bios. If it is, you might want to set up the 1TB drive as the boot dive for testing purposes
