Unable to boot up pc after new amd athelon xp mother board install "help"

I just bought a new mother board and im having problems booting it up. i have stripped to just the harddrive, memory and thats it. when i boot it up when i first installed it i was able to get to bios screen. plugged a existing harddrive and got to choose start windows normally or last known good configuration. chose boot up normal and i heard a zap and i havent been able to boot up pc ever since. i boot up pc now and the keyboard flashed real quick and thats it. i dont get any display. tried another power supply and still no luck. tried another amd processer and still no picture. i then cleared cmos with jumper and that didnt help either. im thinking possibly the motherboard??? i have ran out of ideas please help.

You obviously configured the hard drive on another mainboard....sounds like you fried the new mainboard with the old mainboard info that remains on the hard drive...play dumb and send it back...

all you need is memory video and cpu, it sounds as if you burnt out your motherboard. any "zap" on a computer is bad and 99% of them are fatal to the component. I would say get a new board if you've already tried a new cpu . only other thing i can think of is to have the cpu in with no memory and see if u get beep codes.

You could have shorted out the mainboard by having a loose screw lying on the board. If this is the case, you need to >...play dumb and send it back...< !!

This is quite likely to be the motherboards capacitors that blew.
Check if you can see any bulging caps near the CPU, in that case you have the problem there.
Anyway, return it to your manufacturer and request a replacement, claim it was a hardware fault on the board.
Good luck,

can you start it without disk attached? just to get a screen?

Also, what motherboard is it? did you plug the 4-pin power connector in for the cpu power?
and, to be complete, check the cmos battery if it still reads 3V.
But i fear for you as you heard "zap"; but...who knows, you can be lucky

just so you know, tmj883 is wrong about a hard disk frying a motherboard.  Can't be done... well not unless you include fitting the wrong hot pluggable RAID disks into rack mounted servers, but that's not going on here.  

Most electrical components either fail in the first hour or run for years.  Just take care with the hardware install next time, and make sure the board is properly fitted, on standoffs (either small brass screws, or plastic studs), and that nothing extra is touching the main board.  Just run it with the chip, ram and vid card to start, and check it POSTS ok.

some build info here:

I have to disagree completely, last year a customer brought in a system with a dead disk. i put in another disk, and it burned immediately. It looked like the ide output fried the disk. However, the IDE 1 plug still worked.
And i know that this guy NEVER opens his computer box, AND it was fine for a year or so.
I even held the system for temporary tests and backups, and it continued working fine, except for the 1 IDE port

Did you get any post/bios codes?
What mainboard did you buy?? Did you check ram compatibility? Try using another ram stick.

Because you get a keyboard chip startup flash but it goes no further suggests that it could be a blown capacitor problem as BjornEricsson has previously stated

nobus - your comment is fair enough, and I accept that a mobo could kill a hd.  I've never seen it the other way round tho, that a hdd could kill a mb.  But hey, you're pretty Godlike with this stuff, so I stand to be corrected if that's the case.

Well, consider what he did : he connected a working(?) disk to the mobo, heard ZAP. Or the mobo fried the disk, or the other way round (short on the disk connector ?)
And what you mean : >>>   But hey, you're pretty Godlike with this stuff   <<<
i'm just a guy with now 45 years experience in computers...

I would try another video card 1st, I had that problem a week ago where the kb would light up and numlock would turn on/off if i pressed it, so I replaced the video card and it worked fine. (only if you can turn num lock on and off after you hit the power)

Tahnks for your answers. the mother board is fried. i took a closer look and found a burnt chip. look lik its time to play dum and send back to hopefully get it replaced with a new one.
reason: bad power supply, it fried the mother board
