I'm having the exact same issue as original poster. Cold boot and on desktop. Usually 5-10 min in I'll lockup and freeze. Requires restart. From then on I have no more issues the rest of the day or night, even when playing high demand games. If I shut down or sleep it's hit or miss if it will freeze again that day. But only seems to do it from a cold boot. No BSOD or any other issues with PC it runs liek a champ other than this freeze usually daily. Event manager shows just the critical powered off without shutting down. I can post pic of my warnings and errors to compare to original posters I can post setup but we have the same MOBO and CPU combo. I've also been dealing with this for 5-6months and it's just annoying and I'd like it fixed. I've tried: New PSU Updated Bios flashed from usb All drivers are updated. CPU and memory are compatible via msi website. Mem test ran all night 8+ passes with no issues Old and new VGA drivers Fresh install windows 10 Fresh install windows 7 Reseated Ram, CPU, cooler with new paste, and VGAs (sli) Power options set to max performance.
