Hello, I've just changed motherboard card, memory and CPU to the new one: gigabyte p67a-d3-b3, intel core i3 2120, Patriot DDR3 2x4096MB 1600MHz CL8.0 Viper Xtreme Divison 2 LLK. I changed in BIOS memory to 1600MhZ 8-9-8-24 1.5 V (instead of 1.65V (i couldnt find option to get it to 1.65V in BIOS, when i changed to 1.6V system didnt run). After 1 day I got BSOD. But i changed back memory to the orginal state and after about 1 hour system just got shocked. BSOD didn't show up, but computer was frozen and non stop i could hear beeeeeeeeeeeeeeeep sound. I didn't uninstall drivers from old motherboard (don't know how). I installed new drivers for new motherboard / CPU. I didn't install again graphic card drivers (I was told i don't need to). I didn't make format either (I'd like to avoid that as much as I can). In attachment everything you want: minidump / Rammon / cpu-z / and seven forums tool logs. Please help me Best regards, Arkadiusz Wlodarczyk EDIT: I'd like to add that each time computer got frozen was while I was watching something on Youtube (I think not 100% sure).
