I had overclocked my e8400 to 3.825. I set my fsb to 1700, dram to 850 cpu v to0.2, dramv to 2.1 nbv to 1.350 and sbv too 1.550. It ran stable for a while I ran prime95 for 10 hours no problems. My temps were a little high for my liking so I bought a zerotherm nirvana and an asus dx and about a couple of weeks later I decided to run at stock to check temps and the what not and when windows booted up I got the bsod and it will happen anytime I boot into windows at stock speeds not with the voltages I used to oc. When I went into hardware moniter in bios I saw that my effciency was ranging between 19 and 25%. I swaped out my psu and same thing could it be my mobo? Please help someone I dont know what to do.
