Hi. I have some problem with my computer: GA-H55M-USB3 rev. 1.0 Core i3 530 MSI R5770 Hawk 1GB Kingston 2x2GB 1333Mhz DDR3 Seagate ST3250410AS 250GB BeQuiet 530W I tested bios from F2 to F10. In F2 and F6 it's stable but from time to time, one on week my computer turn off and turn on again. Diffrent bios for example F10 - Windows started, working about 5 minutes and turn off... Bios settings default. Temperature OK. What's that guys?
