Hello everyone! Any help would be greatly appreciated. I spent quite few hours searching for issue but I am unable to find it. This is a long post please do take your time to read it and I thank you for reading it in advance. I did install latest Nvidia driver around 7-10 hrs before playing the game. I was playing The Division 2 today and all of a sudden the OS crashed with BSOD. So naturally I restarted it and again after I login, BSOD!! This kept on happening so windows troubleshoot popped up. I hit 1. Repair- no use 2. restart in Safe Mode to delete the driver - no use 3. system restore - it showed me a point before I updated Drivers so I clicked that and same while it was restoring it **bam**! *BSOD* Then I put ISO in Pen-drive/Thumb drive/Flash drive and launched Windows 10 setup. In the options I hit 1. repair - nope nothing BSOD at the end[as a cherry on top]. 2. setup windows - does install but at the end it asks for restart as soon as I do it well you guessed it - BSOD! So I did few things based on what others mentioned 1. Installed OS again after formatting the drive in which I had my OS as I mentioned above. 2. Replaced SSD with my friends brand new SSD nope same issue it installs the OS and then BSOD. BSOD Errors which I got in no particular order: 1. cache manager 2. irql_not_less_or_equal 3. DPC_WATCHDOG_VIOLATION 4. KERNEL_SECURITY_CHECK_FAILURE 5. System_Service_Exception My Config: Nvidia 2070 Super Intel I7 9700K Corsair Vengeance LPX 16GB (2 X 8GB) DDR4 3000 (PC4-24000) CORSAIR RMX Series, RM750x, 750 W 80+ Gold Gigabyte Z390 Gaming X Hyper 212 Black Edition Corsair Force GS 240 GB SSD[This has OS] 2TB Seagate Barracuda 7200RPM Also I bought my PC 6-7 months ago all of them from Amazon US. Before I had an issue where my PC used to froze when I restart my PC so changing my SSD did work. So I never again bothered with this issue but as a precaution I never used to shut down my PC instead I did Hibernate my PC. Thank you EDIT: Thank you all guys/gals. I think I found the issue. I tried 2 things: Removed CMOS battery and then placed it back. I also cleared CMOS[I think it was through CLR_CMOS]. I removed one RAM stick and checked same thing and did same with other stick but no change. So I borrowed 2 sticks from my friend and placed it in 1 & 3 slots same issue. But then I placed the RAM sticks in 2 & 4 slots and it worked. I am currently talking to Corsair for possible replacement. They suggested me to send them pics and all details related to purchase.
