My laptop shut down and lost everything?

So my laptop shut down and lost EVERYTHING. Like, I had to reset it as a new computer. It wouldn't restore to an older backup or anything, I had to re-register it! So mad.

Anywho, I had a ton of music (over a thousand songs) and they're all gone which is what I'm most upset about. I redownloaded iTunes and only the songs I purchased showed up, and I didn't get all my songs off iTunes…
I have an iPhone and all my music is on my phone, so I'm wondering if when I plug in my phone the songs on my phone will transfer back to my computer or will they disappear when I sync my phone? I really don't want to chance it and lose all of my music because I don't want to redownload all 1000 of them.

If someone has expierienced the same thing please let me know what you did to get your songs back!

I DROPPED MY IPHONE IN THE TOLIET

Okay so my iphone fell off the bathroom counter and fell in the toliet, it wasn't even in there long because i pulled it off right away. I pulled off the case, wiped it down with disinfecting wipes and then set it in a bag of rice. The only problem is, i can't shut the phone off because the first time i tried it turned right back on without me touching anything, and then the screen stopped working. The second thing is the flashlight is on. Before when my screen worked for the second it did, i clicked the button to turn ON the flashlight, and the light only got brighter. So when i turned it off the light got dimmed. I'm planning on leaving it in the rice overnight and check it when i wakeup in the morning. But what should i do about the light & will my phone still work?!

How to know if this iPhone cover will protect my phone?

My dad got me a $10 Accellorize cover, but I can't find anything online about its reputation. I've seen friends drop their iPhones in covers from face-level and it not break, and I want a cover with that level. How much would I have to expect to pay? Name as many brands that are known for that level of protection (not necessarily waterproof or anything). Or will these $10 covers work too?

Will the more-effective brands feel heavy in my pocket?

How to install drivers properly on my PC?

My new Windows PC was running quite well at first, I connected it to the internet and installed some of my games, but after I tried installing USB drivers it decided not to allow them to be installed. Every time I start up my computer it says, "Installing Windows Updates," then it fails, restarts, and lets me log in without having installed the driver updates.

When I plug in my USB Keyboard it seems to work but I can't charge my iphone or use a flash drive.

I tried updating the Apple Usb Driver spoftware but my computer said, "access denied," after it had found the appropriate driver software.

I can't install itunes either because it never installs correctly but everything else I download (i.e. Google chrome and several video games) seem to install just fine.

Any solutions?
(I have service pack 1 btw)

Iphone 5c only charges at certain angle?

I got my iphone 5c at Christmas and it suddenly wasn't charging and then when I moved it to a certain angle it would charge. I got caught in a heavy rain shower but it only got wet on the outside and was wondering would it have anything to do with it. I have also noticed that were the cable ends to put it into the phone looks bent. Is this just a case of get a new charger or will I have to send my phone to get fixed?
