My Laptop Slow Start up, Crash after sleep, Audio Service not running!

Toshiba Satellite Window 7

Ok. so the past couple of weeks my laptop has been running incredibly bad.. First Problem arise when I put my laptop to sleep. It was working when it was brand new, no problems whatsoever. But lately every time i would put my laptop to sleep, it would crash after been woken up. By crash i mean, everything freezes, nothing moves, cursors frozen, nothing.... So i stopped putting it to sleep.

2nd problem was after the sleep problem, Whenever i enter a some sites, my laptop completely freezes. Eg. (i searched methane on Google the other day for homework and my laptop completely froze, had to forcefully shut it down. It wasn't just the internet browser, it was my laptop as well, nothing was functioning. Its not a one time thing because every time i search up methane it crashes .. ) Basically i would just stop searching up stuff...

3rd Problem Arrived today, Laptop would take extremely long to start up. Like 10-15mins to start up. This problem just showed up today, and i have no idea whats wrong!!

4th problem is minor, my audio service is not running. This problem came up at the same time as the long start up problem. The sound still works but i can't see the icon on the bottom right corner on my screen.

SOLUTIONS
- I've tried scanning computer with viruses, couldn't find any?
- I've tried clearing cookies and cache, doesn't work..
(Laptop freezes no matter what browser i'm using)

I'm not really good with computers to I don't know whats wrong at all! If someone could help, it would be kindly appreciated :) If you need anymore information just ask.
I'm not sure about type of laptop, graphics card and all the other useful stuff, so if anyone could tell me how to find these things out i will.

Any help would be appreciated !! Desperate need on help ~~
