something def isn't working properly

[Danadcorps]

hey guys i got a big problem. I am in college right now so i live wiht 5 other guys. To make a long story short, 2 of them got drunk one night and one of them accidentally fell on my computer, tipping it over since then it hasn't been working

btw my bro and i have very similar systems (monitor, video card, network card, memory and processor are all the same)
only differences (hard drives, motherboard, speakers, and he has a sound card)

my old motherboard (albatron kx400-8x)

heres what i did:

brought my system home (w/out monitor, keyboard, mouse, or speakers....so just the case and everything inside of it)
bought a new motherboard (asus a7n8x)
installed new motherboard and put everything on it.......didn't work
took out my hd, put my brothers hd into my system........didn't work
put my hd into my brothers system *set my hd to master* went into bios and......didn't recognize my hd
put my bros hd back into his *set his to master* with mine in his comp *set mine to slave* went into bios and ......didn't recognize my hd
took out my hd, put it back into my system
took out my vid card, took out my bros vid card, and put my vid card into my bros system....everything worked fine in his comp
put the vid cards back into the appropriate places
took out my new motherboard and put my old motherboard in ...installed everything back in

here are my conclusions:
my video card is fine
my hard drive is fried
my processor is messed up

whenever i say "didn't work" this is what i mean: put the power on and the fans move (all of them). i can open and close my cd-rw and my dvd-rw as much as i want, but i don't feel my hard drive moving at all. monitor doens't display anythign (it just says that there is no signal)....can someone please help me and/or confirm my results

btw, i didn't want to take out my bros processor and put it into mine cause i don't want to take the chance of screwing his system up too.

thansk for you help! (for those of u who do help me)

Your memory could be the problem not the CPU so you will need to try swapping out each to see which is the culprit. Try the memory first as it is the easiest to swap out.

Usually nowadays lack of or bad memory will give you loud annoying beeps, where as a non-working processor gives you no sound at all. But you should still check it.

so just swap my memory wiht my brothers memory? what should happen when i swap the memory cards? (guessing it should work normally)

If memory is the problem it should work fine then. Be sure you are using the same memory as your brother's system!

You also could have a bad power supply. Just because it supplies power to the fans doesn not mean it's good. The PS converts power to different voltages depending on where it goin. The voltage to the fans, drives, etc.. are one type the voltage to the motherboard is another.

You just need to go through the process of elimination until you find the culprit! It's best to take everything out except the video card & MB/CPU/Mem and try to see if it works.

ok will do, but 2 more questions hehe

for the memory, you mean same as in same size and speed right? (ie DDR400 512mb)or something like that

and the last one: how would the system work with just the mobo, cpu, memory, and vid card? i thought it had to have power in order to work (or do u mean use my brothers power supply?) and if i was to just test them alone (no PS) then what should happen?

btw thank you sooo much!! (its actually kinda fun having stuff broken cause then u learn how to put it all back together!)

ok i was at school this week and i just got home so i had a chance to test stuff out.

I checked my memory in my brothers system...worked perfectly

i checked my power supply in my brothers system...also worked perfectly

i also checked my harddrive one last time (i really didn't want it to be fried! it's capacity was 120 gigs and it was almost full of stuff i liked!!! but it wasn't being recognized in my brothers system.

btw i wanted to try swapping the processors but my bro has a mammoth size heatsink on his processor and i don't know how to get it off!! (its freakin huge man)

to recap:
checked power supply
checked memory
checked videocard
and they all work perfectly

i checked my hard drive and it isn't working. so i'm gonna have the kid buy me a new 120 gig hd and an AMD Athlon XP 2700+ 333 FSB, 256K Cache Processor Retail (so it comes with heatsink and fan) for 120
