WEll i'll start this off saying that this was a christmas gift from my father and i to my mother, that still has not been delivered, and it's my fault. I've wracked my brain as hard as i can, and gotten nowhere (even made some negative progress).

So to start off this story, i got myself a new motherboard, processor and video card (stuff in sig) and my mom's computer would get my Abit IC7-G, 2.4c, and 9800 pro, and then all new other crap. Basically, my new stuff came, and died promptly, so i put my mom's computer together and it worked, installed windows, drivers, everything fine, and i was using it as my main rig while i waited on the Egg to send me replacements for my DOA stuff.

mom's computer:

Abit IC7-G
p4 2.4c
512mb Rosewill pc3200
Radeon 9800 pro
80gb WD HD
dvd-rom drive
52x cdrw
sound blaster audigy
enermax 430watt

So my new parts come, and i get my computer working (fast as fuck btw, i LOVE it) and then i decide it's time to replace the noisy crystal orb that i'd had on mom's 9800 pro (the fan had started making noise) so i got the stock 9800 pro cooler and swapped them, I plugged the video card back in and shut the case. Hit the power button and power on, no post... hmm, strange. I found a working gf4 4600 agp to test with.... still no post, so i guess i didnt kill the vid card. NOthing i can do will make the computer post, i tried taking out the vid card, memory, processor and nothing made it come to POST, actually, it eventually turned into something worse, the computer not turning on at all.

So i tested the PSU with the pin 14 trick, and it fired up. I went to my local computer store and managed to find a motherboard that was socket478 intel chipset and DDR1, so i picked it up for $50 for testing purposes.

Anxiously, i got home to throw this new board in figuring the old one was dead and that was the whole problem. Put it in and i get power again, but still no post. At this point i realized that i've been doing this all without a PC Speaker (stupid me) so i went and got one. It does not beep at all.

So where we're at right now, i've tried 2 motherboards (and seemingluy killed one) 2 video cards, and i'm still not posting (no video response at all).

I'm pissed off cause i cant figure this out, and i really need to get this done because it's weighing on my consicence that my mom dosent have her computer yet.

any suggestions (i'm sure there's things i've tried that i forgot to mention, so just throw out suggestions and i'll let you know if i've tried that and what the results were. Thanks in advance.

here's the thing... i thought dead/no processor would still result in a beep-code from the motherboard... AND how the hell did i kill the proc when all i did was replace the HSF on the GPU?

dead proc is the worst case scenario, as i'll have to eat the cost of a new Proc.
 
The processor is absolutely necessary for a post. So if you have a dead processor or no processor it would demonstrate the problems you are describing.

Donno about why it would have died, knowing that 478 was a popular pin layout is there anyone that would let you borrow a P4 to test?
 
well i'm putting out feelers for a p4 in the FS/FT but no bites yet... any other suggestions?

i have a 2.0a sitting around i guess i'll have to try that.
 
well i threw in that 2.0a and no difference.... no beeps, fans/hd/optical drives working, HD and Power led's stay on.

WHAT THE FUCK!????!@?!
 
I had the same problem with my old Abit KA7 motherboard. Then I looked around on the motherboard and noticed some of the capacitators had blown. Check yours.

edit: Nevermind, I see you've tried another motherboard.
 
yeah, this is the 2nd mobo, the first one (abit ic7-g) exhibited the same problems as the current one (asus p4p8x) but the abit went from bad to worse to the point where power on was impossible, but the p4p8x will power on just fine.

so whatever happened seemed to kill whatever is making it not work now, as WELL as killing my ic7-g (which i now have to RMA).
 
come on guys, i know that a whole forum full of us can figure this out... but i know i'm sure as shit out if ideas... you stare at one thing long enough and sometimes you cant even see it.

i'll have to try a different psu just for the hell of it... ovbiously the 12v rails are good as the fans run, but what about the 5v and 3.3?
 
Try clearing the cmos on the mobo. Sorry if you've already tried that, It's the best I could think of.
 
been there done that... just tried another psu, brand new, and no difference...

:(
 
Did you use the fiber washers under the screwheads when you installed the motherboard?
 
Hmmm........did u install any more standoffs (little brass screws) when you installed the new mobo? Try this, try and run everything OUT of the case on a table, and see if you can get it to post, also are you positive you attached the molex connector on to the vid card? anyway, good luck, if this doesn't work PM me and i'll see if I can post any more suggestions.
 
no, i didnt use the fiber washers, but i never have (and every computer i've ever built has worked... i dont understand) , so i didnt think to try, i'm tired and drunk right now, so i'll try the out of the case thing tomorrow, i've tried it once, with the ic7-g, before it died...

i'm running out of options here guys, 2 motherboards, 2 video cards, 2 motherboards, 2 psu's, and 1 set of 512ddr, but even if i take it out, there's no difference....

i have no idea what might be left? :(

i installed one more standoff (the one near the power/led/rst/ connectors, i've never, ever installed that standoff in any other computer i've built (which is many)... so i'm skeptical that it is the problem, but at this point i'm open to anything, this has me to the point of tears in combination with the stress that i'm dealing with these days.... bills suck and living with the woman you love is way harder than you can possibly imagine.

edit: yes, the 9800 has had the molex connected, and the 4600ti has no molex to connect.
 
Yeah, I've actually had that happen to me. I got a new comp case and I put in too many standoff screws....one of them shorted the board out, so it wouldn't display video/post. It took me several days to figure it out. I took the board out of the case and reset the cmos and it worked. So, I hope that helps. Good luck. ;)
 
i SO hope you're right (/valley girl)... i'll try that a little later before the friday night festivities begin.

any more suggestions for when i tear into it again?
 
no change when removing mobo from case.... confused....
 
hmmm...weird. When I had the problem of my board shorting out, I pulled it out of the case then reset cmos. Resetting the cmos was necessary for the board to work, so I'm not sure if you did that when the board was out of the case or not. If so, then weird indeed.

You have tried 2 mobo's, 2 video cards, 2 cpu's, and tested the psu, so none of those are likely to be the problem. The only other essential component for getting a post would be the ram. Maybe you could borrow a dimm from a friend or something. If I lived closer I'd let you borrow one of mine. However, being corsair xms, I don't think you'd want to give it back :D .

I hope I was able to help you. I'll keep thinking about it though.

I did notice that the abit ic7-g mobo supports only 800/533 FSB cpu's, so the 2.0a with the 400mhz FSB would not work with that board.....not sure if that's significant or not, just been thinking.
 
oh man i hadnt thought of that, great idea. So if my 2.4c is dead and it wont work with the 2.0a... it would look like the same symptom.

hmm, i'll try resetting the cmos right now.

edit: thanks so much for taking the time to think about it, it really helps to have 2 heads on it cause i'm out of ideas after 2.5 weeks.
 
you try manually jumping the power leads with a screw driver or something instead of power button? ..or plug your reset to the pwr and hit reset button and see if it fires up

if that dont work ..it could still be the psu even tho you got it to come on by itself.

with bad ram it should still kick some fans on and beep at yuh

if vidcard isnt properly seated , again it should still come on (fans) , but just wont post.

even bad cpu , it would still fire up fans

when you fired up psu by itself ..was it plugged into same power socket?

I've had sockets go bad on power strips where one would work and the one next to it wouldnt if the whole thing didnt go belly up all together.
