I have been using my computer normally for several month, but out of nowhere, today it starts to randomly crash and BSOD.

Symptoms: A few minutes after boot, applications would randomly crash, then after a bunch crashes at once, windows would freeze up for a second or two then go into BSOD.

My minidumps suggest that it crashed in address ntoskrnl.exe+7cc40

What could be the cause?

Here are the dumps: Link Removed due to 404 Error

I tried to do a system restore to the last restore point I had but nothing changed. I did the window's memory diagnostic tool and it reported no problems.

Been running memtest86+ for the last couple hours and so far no issues either.

Experiencing random crashes and Blue Screen of Death (BSOD) issues can be concerning. The fact that you've already tried some troubleshooting steps like performing a system restore, running the Windows Memory Diagnostic tool, and using Memtest86+ is a good start. The address ntoskrnl.exe+7cc40 where the crashes occurred often indicates issues related to system kernel operations. Here are some common causes for such crashes:
  1. Hardware Issues:
    • Memory Problems: Even though the memory tests showed no issues, still, faulty RAM can sometimes cause intermittent problems that may not be immediately detected.
    • Overheating: Check if your system is running too hot. Overheating can cause instability and crashes.

    []Software Issues:
    • Driver Problems: Outdated, incompatible, or corrupt drivers can lead to system crashes.
    • Software Conflicts: Incompatible software or conflicting system settings can also cause crashes.
    [    ]Malware and Viruses:
    • Malicious software can sometimes cause system instability and crashes. Given that you've already checked the memory, it might be worth exploring other possibilities:
      • UPDATE DRIVERS: Ensure all your drivers, especially graphics and chipset drivers, are up-to-date.
      • CHECK TEMPERATURES: Monitor your system temperatures to rule out overheating issues.
      • CHECK EVENT VIEWER: Look at the Event Viewer for any specific error messages related to the crashes.
      • CHECK HARD DRIVE: Run a disk check to ensure there are no issues with the hard drive.
      • MALWARE SCAN: Perform a thorough scan for malware and viruses.
      If the issue persists, analyzing the minidump files could provide more insights into the specific cause of the crashes. If you can provide access to the dump files, I can help analyze them to pinpoint the root cause of the crashes.
