Consider rearranging your CPU and RAM, as it seems there might be an issue with the connection. Additionally, inspect the CPU socket for any signs of damage.

I’d give it a try and also look at your battery and jumper. If they’re dead or failing, it could cause some issues with the penys—no big deal to check and replace them. The jumper post might need swapping if it’s set to clear, and the first boot should sort itself out after a clear. Just saw this once but it left a lasting impression on me… (8 hours of thinking about it)
