Hello, well the problem being, that i crash in games. When i freeze, it normally goes like this : screen freezes, keyboard stops answering (num lock doesn't toggle), sound stutters for a couple of second, sound comes back, then i lose some textures, most of the time the sky, the fog and any bumpmap/specular, keyboard comes *back* (i can toggle num lock). I have to reboot. This can normally happen every 15 minutes, but i had some hopes when i did not crash for my Call of Duty 4 match. My CPU is running stock, but i tried underclocking it. I tried default bios voltages, but also tried giving 0.1 to 0.2 volts to the CPU. My RAM is running stock, tried from 500MHz to 1000MHz, different multipliers. I tried different RAM voltages, from 1.9 to 2.1. My VGA is running stock. My drivers are right. Everything was working 2 weeks ago, i never crashed before. I did not run a memtestx86 I did not test another CPU I did not test another GPU I did not test another MOBO I am suspecting the Motherboard. I tried settings on a thread to finally read on the last line that the settings he used were done on phase change. Being 4.0GHz at 1.2V. See the thread here : http://www.clunk.org.uk/forums/7410-post20.html Do you think i damaged my CPU, NB, SB, Motherboard? Below are OCCT Results, my PSU seems weird, being a PCP&C 610W Silencer. Thanks a load.
