Problems with sound and system loading. What to do?

Question

mint

Good day! A week ago I installed Linux Mint 17, the time was later and therefore turning off the computer. rescheduled for the morning.
Turning on the computer the next day, I found that the sound is not normal, that is, it comes in jerks and not through 3 speakers
(I have a SVEN subwoofer and 2 speakers. Creative LS audio card), but only the left channel and subwoofer. For a long time I tried
to fix something on my own, but nothing happened, or rather it turned out to delete a part of something ... At
the moment, the system is not loaded. Constantly asks for a password for a second, it looks like it's loading ... and again asks
for a password. To be honest, in Linux I am zero or maybe even minus zero. If anyone decides to help, I will be glad to accept
help. Thank you in advance.

Install Windows. Linux is not a home OS.
