My five-year-old PC recently began crashing with frequent blue screens. The first incident happened while I was browsing, followed by several more crashes and eventually a black screen with the CPU debug light illuminated while the fans continued running. I reseated the RAM, checked the cables, updated and reset the BIOS, and even reseated the CPU. Reseating the CPU seemed to help temporarily, but I later discovered that temperatures were unusually high, so I installed a better CPU cooler. The system then worked normally for about three weeks.
Today the crashes returned. I have seen errors including DRIVER_OVERRAN_STACK_BUFFER, PAGE_FAULT_IN_NONPAGED_AREA, and KERNEL_AUTO_BOOST_LOCK_ACQUISITION_WITH_RAISED_IRQL. Sometimes the system restarts several times, fails to get past the Windows loading screen, and then shows a black screen with the CPU debug light on. The fans keep spinning, but the computer becomes unusable.
The system has a Ryzen 5 3600, RTX 3060 12GB, 16GB of DDR4 RAM in two sticks, a 500GB SSD, and a 1TB hard drive connected to two monitors. It runs Windows 10. I installed a Windows update yesterday and updated the NVIDIA driver about a week ago, although the PC continued working normally afterward for gaming and video editing. I need to identify whether the problem is caused by failing RAM, the SSD, overheating, the motherboard, or another component. I also need to protect my files and get the computer working again because I rely on it for video-editing income.

The different BSOD codes point to a problem that needs proper crash-log analysis rather than one specific error. If you can reach Windows or Safe Mode, check C:WindowsMinidump and copy any recent dump files somewhere safe. Those files can often show whether a driver or hardware component is triggering the crashes. If no dumps are being created, configure Windows to create small memory dumps and check again after the next crash.
Back up your important video projects and personal files as soon as possible. A failing SSD, RAM, power supply, or motherboard can cause several unrelated-looking BSOD messages. Since swapping the RAM did not immediately solve it, test each stick separately, run a memory test, and check the SSD's health and the Windows drive for errors. Avoid repeatedly forcing restarts until the data is backed up.
I already tried swapping the RAM sticks without success, but I still need to test them individually and check the SSD. I don't currently have another SSD available for comparison.
