I have been running into WHEA_UNCORRECTABLE_ERROR bluescreens where windows crashes so hard it won't even dump its memory while playing destiy 2 - windows gets stuck at 0% dump no matter which hard drive is used to write it to. Other games don't crash it, and it only happens in kelcrash and expedition. I didn't run into it in crucible, or other. I highly suspect this is battleeye. It's happened 5 times each time in kelkrash or expedition. I've been through windows sfcscan which found 0 corruption, I've found no error with my hard drives, my system is at normal temperature with no overclocking. I haven't seen this happen with other games, but I don't tend to play games that have anticheat software (warframe, doom2, doom64, ziggurat 2). I can give my specs if that would help, the only thing I haven't done is run a memory test but given this only happens in destiny 2, with that one specific activity, and only this past week, I have heavy, heavy doubts that this is actually more than a shader or something. It does not happen systematically either. as for specs, I have: Operating System Windows 10 Pro 64-bit CPU AMD Ryzen 7 3700X Matisse 7nm Technology RAM 32.0GB Dual-Channel DDR4 @ 1599MHz (16-18-18-36) Motherboard Micro-Star International Co.
