Hi there. I have not had bsod in years but lately they happen every so many hours now. The only things that have changed is moving my os from c drive ssd 128gb to a 256gb ssd by the clone method. The only drivers i have changed recently would be the nvidia drivers, then the odd windows update updates that i get now and then. All other drivers are the same as when the system was running smoothly. I searched what 0x000000d1 could mean but all they said was maybe ocing issue which i doubt but on the off chance i have upped my volts from 1.200 to 1.210 just to see if it helps today. Im guessing it might be nvidia drivers issue i dunno tho 100%. Included is a minidump from todays bsod hopefully some kind soul can look at it and debug it as i have no clue how to do that im more of a build pcs and oc them etc, im not used to the debug files stuff. As of the guide thread how to report these i have included the w7f tool zip a cpuz of all tabs and a passmark ram html report. I hope this is all that is required. My system is i5 3570k oc :4.5ghz been rock stable 8gb corsair low volt memory, been rock solid again i must point out. gigabyte z77 d3h mb with a old but stable bios, was stable for years, so dont need latest bios. gtx 670 gfx card with latest drivers. Gona maybe roll them back to a driver i know that worked ok i guess using DDU. asus dg scard with unified drivers. win 7 64bit with all updates to date afaik, it said no updates when checked today so.. Latest dx is on etc. Anything else needed let me know cheers.
