"Added More RAM, Windows 10 Fails to Boot"

After purchasing the RAM modules from Best Buy, I encountered an issue where my computer would not boot up properly after installation. Despite the fan running, my monitor displayed nothing. My computer has four slots - two white and two black. The initial 8GB RAM module was in the first black slot. I attempted to install two new 8GB RAM modules into the two white slots, but my computer still failed to start. Subsequently, I tried installing just one of the new modules into the remaining black slot, but the issue persisted. Ultimately, I had to remove the new module, and my computer resumed normal operation with only the original module installed.
