For passwords, LastPass is free and encrypted. You can store all passwords and other sensitive info (credit card numbers, bank accounts, etc.) under one master password. You can also print the stored passwords and info if you want. There's a paid version, as well. I've used the free one for years. When I buy new software or sign up for an annual account, I add it to LastPass so I can check it whenever necessary.
Good luck, I bought a new computer last January after having used my old one for 11 years. Like yours, it was becoming unreliable.
