Check if the blinking pattern is a known issue and see if others have documented it.
You're dealing with a system that's showing signs of RAM issues. The erratic flashing of the power LED during boot loops and its rapid blinking on startup are consistent with problems in the memory module. The fact that it stabilizes after a short period suggests a temporary glitch rather than a permanent failure. Since you've already replaced the RAM and tested it under stress, it's likely the faulty RAM cells are causing the instability. Checking for error logs or using a memory diagnostic tool could provide more clarity.
