busted!

my pc's busted. don't know why. when i got home on sunday, my cousin told me there was something wrong with the monitor. i checked it, the screen was blank. green light's blinking, but nothing else was coming up. i unhooked it from the back of the tower, turned it on, and saw the rgb box going around the screen. wasn't able to read what's written because it was in korean. thought it had something to do with the video card. so, i called peepee up and told him what's wrong. he also said the video card's busted. easy to replace, right?! no. my sister bought the pc as a bundle (when i told her not to buy bundled pc's), so everything's onboard.
i told momma what's wrong and i told her that the video card was onboard so the entire mobo has to go. she asked how much it would cost to replace it. i told her i'm not yet sure. i plan on rebuilding the pc. i wanted to replace the motherboard and replace everything in it. i wanted to change the ODD to a dvd/cd combo drive. i also wanted to change the processor to a core 2 duo and add more HDD to it. i also plan on removing the floppy because it's so retro. i want to keep the casing, if i could, as well as my monitor.
so right now, we pay the monthly dsl dues but we cannot use the computer. it sucks! can't even check my blog at home!
