If ur pc restart, its either ur proc temp high so auto restart, u OC not stable or my best guess is, ur psu not enough supply. Wat kind of psu u using?

edit: just saw u did put stf50W. Well better get a higher wattage psu on the safe side, as for temps, load at 86 is . . . high for me, use riva tuner, increase ur fan speed of gtx275 during gameplay.
