Well it's good that you backed up, but just because it's above the average age doesn't mean it cant be fixed, my favourite LT lasted me over 5 years and in the end I only replaced it because it couldn't play some of the games that needed a faster processor. I'd run it down to a local repair shop and see if they can fix it, it may be something as simple as a loose connection or as complex as a motherboard but you won't know until you have someone look at it.
Either way a delay isn't the end of the word, it's just a delay.
Oh and you really do need to change the CSS on this page, your 'blog posts are grey text against a black background, they are almost impossible to read.
edit: thanks for the CSS update, much easier on the eye.
