Dell Inspiron 15z Ultrabook 3 beeps black screen all of a sudden!?!

Hello,

I purchased a brand new 15z ultrabook dell inspiron laptop 2-3years ago and only used the laptop for college and have taken really good care of it.

Yesterday, my computer wouldn't go past the dell logo screen because it was fixing the caches.

Today, i turn my laptop on and its fullu black screen with 3 beeps. I have tried resetting the laptop already.

Just very frustrated i pay 1 thousand bucks for a laptop and it dies so easily. Never will buy another Dell.

Can anyone help me resolve this problem?

Thanks!
