hey all

i recently purchased a new system with these components. it seems to be freezing a lot, causing me to have to reboot often. when it freezes, all the parts seem to be working as far as i can see in the case.


Mobo: ASrock z77 extreme-4
CPU: i5 2500K
GPU: Gigabyte 7850 2GB overclocked to 975mHz
RAM:G.Skill Sniper 8G Kit (4Gx2) DDR3 1600
HDD: Seagate Barracuda 500GB 7200RPM
Optical Drive: Samsung SATA 22x Black DVD RW
Case: Coolermaster HAF 912 A
PSU: ASUS U-75HA 80+ 750Watt

please let me know what your suggestions are. this was my first build, so the problem maybe could have been in the way i put it together, but i doubt it.
