So many problems with my laptop?

Since you can't type your pword the first thing I would do is go to user accounts and remove the pword of the admin account. It sounds like you have a mive spyware/virus infection. Do a system restore, just pick a date before you started having these problems. Then you need to go to www.downloads.com and download malwarebytes anti-malware it is number 6 on the most popular list. Update the program then run it. This should wipe out the spyware that is on your pc. Hope this helps. If nothing else disable that pword before you freeze up or something.
