Pc hard crashing ever since the latest update introducing RedSec
Update:
I’ve finally fixed the issue — and it turned out to be a memory slot problem, not a RAM issue like I first thought.
On this motherboard, the primary memory slot is the second one (A2). For two RAM sticks, the recommended configuration is slots 2 and 4 (A2 and B2). However, during testing, I discovered that the fourth slot (B2) is faulty.
I stress-tested each RAM stick individually using OCCT (maxed-out stress test for 15 minutes). Both sticks passed when tested alone in the second slot, but when I installed them together in slots 2 and 4, the system failed the stress test and hard-crashed — confirming that the RAM itself wasn’t the problem.
To verify, I experimented by placing the second RAM stick in different slots. The system worked fine with it in slot 1 (A1) but not in slot 3 (B1). That confirmed it’s a motherboard slot/channel issue.
Now the system runs perfectly again with 64 GB of RAM. From the BIOS, I simply loaded optimized defaults, disabled XMP/EXPO, and everything has been stable since.
Hopefully, this helps anyone facing similar random crashes or black screens — sometimes it’s not your GPU or drivers, but a faulty memory slot causing instability.
