Hm...Well in this case, (pun 1) I'm actually not opposed to this and in fact I'm a fan (pun 2) of this, to be honest. (pun 3) I'm so wired (pun 4) to get back on (pun 5) and play some fangames. I'm practically gonna have a cord (pun 6) shirt by the time I get the computer up. I bet the keys are bored (pun 7) of just sitting there waiting to be clicked. (pun 8) Better get my mouse out, I hope it's like not in the wall. (pun 9) I better put some sort of screen (pun 10) over my eyes after how long I'll be looking at the screen. I haven't played fangames for so long, you know how bored I am? Mother, am I bored. (pun 11)
The thing is acting a bit screwy (pun 12) though so I might need some help. It's really pushing my buttons, (pun 13) if ya know what I mean. It's such a disaster! Almost as much as a disaster as my screwdriver. It's driving me up the wall! (pun 14) maybe I should pick up some computer parts. Out, let (pun 15!) us be!
Well, I just picked up some parts. Man, it was a hard drive! (pun 16?...) it was getting dark and the mosquitos gave me a giga bite! (pun 17.) It was less of an experience than a cookie. (pun 18...) Well, better pull up my sleeves and zip (pun 19...Almost there.) up my jacket! (pun 20! One more?) I still had to ram (pun 21!) my computer for it to even work.
I think like 21 puns should be enough by now
Anyway, this is an interesting topic. I've never seen something like this and I hope it'll help some people.
I hope you're having the time of your life!

My PC wont start up. I can power it on , but all i get is empty black screen, not even the GIGABYTE splash screen appears. Once I turn it on, i can't turn it off with the power button, I have to use the switch on the rear panel. Also, LED on the CD drive keeps blinking rapidly. What could this be?

Yeah, I think your hard drive may be dying. While opening the computer mash F8 to open advanced options, then select startup repair. It sometimes works.
If it doesn't you can also try system restore or just reinstalling Windows.
