I just built a new computer and everything seems fine except when I have multiple things running or am playing a game or anything that uses a ton of memory my system crashes and turns off. No BSOD or anything it just crashes. I turn it back on and everything is good again. If I just leave the computer running without playing games it'll run for days at a time fine. I have 2 sticks of 1gb g.skill ddr2 800 ram @ 4-4-4-12 2T 2.0 volts. Ive tried differnt timings and voltages and everything but still the same results. Is this a memory problem or what do you think? Also, i tried memtest32 with both sticks and it got to about 10% and crashed. Tried the sticks invidualy and same results. What should I do now?
