A couple of years ago, I added more RAM and a bigger SSD to my laptop. After I did that, my computer started taking long time to boot. I don't know why.
Yesterday, the computer froze hard while playing a game and I had to do a hard reset. The computer didn't want to come back to life, but eventually it did and entered a BIOS diagnostic screen. I let it do the self diagnosis and when it finished, it said it found a memory issue and fixed it. Now it boots up in seconds like it did when it was new
