heres my story.
last Christmas i built my first computer, for my little brother. up till this point i never build a full computer, but i have swapped everything else in the computer except the cpu.
so here i am putting the cpu in, not wanting to break it, because my little brother wouldn't have a computer, and id me out 600$ but ii wasn't even thinking the money at that point. so i learned a new thing that day, the athlon II x4 620 heatsync takes a hell of allot more force than you think it would to put it on.
it took me almost an hour to figure that out, thankfully i did.
now his motherboard, i cant think of it off the top of my head, has a different problem.
so everything it all hooked up, teh cpu ram psu motherboard and everything else it hooked up right. so i turn it on, F@%^in red lights. i quickly turn it off thinking "OH S!@#, WHATS WRONG did ANYTHING break" so im reading the manual in a panic, thinking i just broke his computer, more sad that he wont get it than im out 600$ at this point, i think "f@#$, if i fried something theres nothing i can do about it now, lets turn it on and figure out what the lights on for"
i turn it on again, and it boots into knopix, and i cant find a single thing wrong with it... it took me half an hour to figure out that the motherboard has red leds, red didn't mean anything was broken. it scared the s@#$ out of me for no reason at all, and all that was running in the back of my mind was "F@#% YOU (cant remember brand, i think it was biostar or gigabyte)"
