new AMD system won't boot

hi, just got my new amd system last nite, installed a net card and burner, i made sure i was properly grounded on the case before doing anything like i always do, the people who built it forgot to plug the floppy drive in too :-)

when i tried starting it up, all the fans turned on as i expected, it ran for about 10 seconds then turned off, no POST signals, display or hard drive activity at all, i made sure all the connections were ok and i couldn't see anything that looked out of place at all, im going to return it and see what the prob is but im just interested if anyone here has had a similar problem?

here are the specs BTW:

AMD Palomino 2100+
GigaByte KT400 w/ AGP 8x
512 MB DDR 266Mhz ram
40 gig hard drive
Geforce 4 Ti4200 128MB DDR
Lan card
Burner
No O/S installed as yet as i didnt need one for it

I had had exactly the same problem with my AMD 600mhz. The problem was...the processor connection. It seemed to be well connected on the motherboard, but it didn't. Check this, I was afraid to break it, but I had to force. After that, all was perfect.

try swapping power sources and/or power cords. gotta check the simplest of things first :p

We had the same thing happen to one of our Athlon XP 1600 systems. It turned out that the person who built the computer did not put in the processor in correctly.

I agree with KissCool.

I would first take a look at the processor connections.

Question... Did it work properly before you added your net card and burner?

If yes... then check those connections again too.

All else fails... bring that **** back to whoever built it and have them fix it.

Why try to fix something that they should have been done right in the first place?

Also reseat video and memory -- no Bios beeps huh? floppy drive was unplugged? hmm.
IS THE SPEAKER PLUGGED IN RIGHT?! lol
Ill bet it isnt.
sounds like these guys need to slow down when building PCs, whoever they are.

Well if its on warranty just take it back and make it someone else’s problem.

some pretty good rules of thumb:

1. if nothing happens at all when you turn it on, it's not getting power.
2. if fans and lights start, but no post, it's memory.
3. if it posts but nothing aftwards, it's the bios. count the beeps in the post.
3. if it can't find an os, it's the hdd.

i hope that helps...good luck!

Jabberwocky, Ive had my sys power on, but not POST and it's always been the display.

EDIT: Jabberwocky, note that I used the past tense, what I meant was, it needn't always be the memory when your system powers on but doesn't POST. It could be the display card, which is what it's always been when I've had that problem.

if i'm understanding you right, you're getting power but no post? i guess the first thing i would check would be the memory, and then the cpu. make sure all the connections are tight...if you could swap some hardware out of another machine that you know works, you could probably narrow the problem down pretty quick.

Hi, I'm not expert on hadware, But I used to have problem like you (I've got Pentium 3 550 mhz 128 RAM) My comp won't boot and I tried to unplugged my RAM card and I switched around and I put it back..
After that I can boot my comp..

Hope this help for you..but if doesn't make sense for you...sorry.. just dummy suggestion from me

thanks for all the input here guys (and gals maybe?), mum took it back today and they checked everything and they concluded that it has to be the mobo that is a bit dodgy, but it seems like this is a common problem with the processor not being inserted properly by the sounds of it, cant really call an AMD a ZIF socket processor than can we?

obviously they didnt even test the thing before handing it over to us since the floppy being disconnected would have shown in the BIOS screen anyway, bit of a worry as the used system i bought from thenm is fine but the new one aint too good at all :-(

i'll post again when i get it back with what happened as a sorta extra input and knowledge thing
