yup maybe overheating try to clean using compressed air and paint brush to remove dust or dirt take special care when you brush your motherboard while using compressed air. try to reseat any cable, sata, power cable etc. connected in the motherboard, if your comp. has a sound card, video card try to reseat them and clean. it help also if you change the thermal paste of your processor. using other memory check it out first if they are compatible. it can cause prob. if the memory are not compatible. goodluck!
