Stressful Week

I couldn't turn on my CPU/Motherboard last thursday. I just got it back today and my friend who checked the CPU told me that it was full of dust.So nothing serious happening inside the CPU. Thanks God,i thought something burning or like that. Because i couldn't online for almost a week,i have to catch up to a lot of things like blog,email,Idol news,etc. I always got depressed when something happens to my computer because i'm afraid the data will lost or i have to install all the programs or i cannot catch up of all the news,email,etc or missing out some important things.
