Strange probelm again

Ok, I'm helpless I don't even need to be building computers. Heres my problem

I'm building a P4 2.8 on as ASUS P4P800 mobo
PC 3200 ram
Nvidia MX 440 64mb card
dvd rom
cd-rw
40GB hd
XP home

I get everything put together turn on the computer start to install windows when i realize I put the floppy cable in backwards. So when the install process needs to reboot I turn off the computer switch the floppy cable around and turn it back on but do not recieve any video. I've reseated the video card, checked my video cable, turned my floppy cable back around but still get nothing. Right now I have the comptuer put away. I'm gonna let it sit for while with no power then try it again in the morning.

Anyone know what happened?

It could be something is wrong with your video card or monitor. I know it was just working but you could have accidentally done something when you switched the cable.
also
can you hear it go through the normal boot process or does it just sit.

I switched out with a different video card but it still doesn't work. I've also tried different monitors but it still doesn't work.

I'm kinda worried now, becuase I don't hear it go through the post anymore. So its just sitting.

Any more ideas?

Recheck your motherboard power cables.

Use the motherboard jumper to reset the BIOS

Oh, and make sure the CPU fan is plugged in cause lots of modern motherboards wont power up without the fan.

I double checked all of my power connectors, and IDE cables. I cleared the CMOS via the M/B jumpers, and battery. All of the fans are plugged in and turning but it just sits there.

However it still does not work. I'm about ready to shoot this computer.
I just can't get it to beep, post, anything.

check your RAM, make sure its in place, or try moving it to a different slot.

cheyenne1212 that's a troublesome one. To me it sounds like something went bad on the motherboard when you switched the cable. What you could do is try the video card in another pc and see if that works.

Am leaning on the side that it could be a bad connection to the board or something went wrong with the board.

I hope that helps.

Guidance...

Well it looks like my worse fears are confirmed.

I'm sending the M/B back. I'v tried everything I know. I've used the Video Card from a good computer, messed with the ram, hell I even tore the whole computer down the put it back together, but it just won't post. So back to the company it goes.

Thanks for your help guys.


btw: when did the hardware forum start appearing on the main page. Must of done this when I was in cali.

unplug your floppy, and then try again.

Already done that. I even plugged the floppy back in the wrong again just for kicks.

I just seem to be having this streak of bad computer parts. I have 3 bad m/b's. All of them are working fine now since I have the new ones, except for this one that I'm sending back.

Oh well, I guess thats life.

I had a similar problem the other day - have you tried using a different power supply? I had a PC the other day that would power on (well, the power lights would come on, but it wouldn't POST, it would just sit there as in your case). I hooked another power supply to it and all was well - you might want to give that a try before you send it back...

Here's my best guess :

-it's not your RAM because the mobo would give three beeps at start-up
-it's not video because it sounds to me like your HD isn't being read
- It most certainly could be that you have a bad floppy/connector/connection.
- All computer will not POST without a floppy connection present.

I would try every possible 'combo' with your floppy before sending it back. Iv'e seen this before.

it could be overheating, i had a similar problem with p4&asus, had to declock my processor untill i got a new fan

You may also want to try installing each piece, one at a time into another working machine. That way, if you find one component (RAM, HD, etc) that doesn't fly in another working machine, you may have a clue as to what the culprit of the problem is.

I'll give that a shot then before I send it back.

they will post.


I'll let you guys know if it worked or not later. Gotta do some other stuff first

Thanks for your help.

guess I'm too high...

geez I Hope not.. or 2 of my machines won't boot..

I take it that no POST to mean that there is no Video.. the Video Card is not Booting and therefor nill zilch other activity.

When ever a problem like this arises.. and it seem most of the steps have been advised or taken. These are the steps..

1/ Undo your last step..
2/ Check the MotherBoard mounting.. suprising the number of times a short has developed between the MoBo and Case. and just the act of moving a cable can trigger a problem..
3/ Remove all extra Hardware, leave the Vid card, and RAM CPU (oh and PSU) andattempt restart
3b/ this is where you start swapping RAM, Video CArd and suspecting CPU or MoBo..


Why did I suspect the CPU... the number of times a machine has come in with a cooked CPU because of a problem mounting the Heatsink,, wil suprise.. ... main probs I have had is with the AMD's but had enough Intels..
Also.. Some RAM Probs WILL prevent the MOBO from Booting to POST.


It looks like a Mobo.. but certainly check the MoBo mounting for problems (I knbow you have taken all apart and started again..but)

Hope you get things going..


Cheers..

BTW:- Hmm yes and it is interesting to see Hardware on the Home page..Good

Undid my last step

Checked my motherboard mounting even took it out and check underneath.

I remove all uneccessary stuff.

And have swapped parts.

When I say no post I mean nothing, no beeps, no video just nothing.

So I guess I send it back.

I found a different company I think I will use. For an extra $15 they will put the whole thing together for you, and all you have to do is put the OS on. I like it this way because it something is bad then they will replace it before they ship it. All of these bad parts I've been getting is keeping me from getting these computers built for these people.

Thanks for your help again.

NOT AN ACCUSATION!!!

Lots of people don't realize just how dangerous static discharge can be. I have seen plenty of examples of ruined MBs because someone didn't ground themselves before handling electronic components. To be honest, this sounds like a case of unwanted static discharge to me. If you do not have a wrist strap, ALWAYS touch the power supply enclosure before you touch anything else in the case. If I don't have a wrist strap available (it happens sometimes) I always make a concious effort to position my arm in a manner that keeps it in constant contact with the PS enclosure or case frame when I'm working inside of a case. Better safe than sorry!!!

I havent heard anything about switching the power supply or if you have used the same PS in all 3 dead mobos. I have experience with faulty power supplies and it only takes one to ruin a couple good mobos. If it was faulty its possible it could have o/led your mobo frying it. I would be careful with that one and check your equipment with a new one.

what i was trying to say was "unplug your floppy, and don't plug it in backwards, and see if it works"

nowhere did cheyenne say that 'it had been sent off already" - it said "i'm sending it off" (the3ntropy)

yes, it did say that cheyenne had unplugged it and replugged it. not unplugged it and left it unplugged. (MemorY) <after I mentioned it, cheyenne did say he already did that, but not before i posted.>

and nuetron, i'm convinced that you negged me just because i had already gained some negative ap's.


and to all who said "read the thread before you post"...

READ THE THREAD BEFORE YOU NEG, IDIOTS!

(sorry to whine about AP's, but i got mega negged on that one, and I didn't feel I deserved it)

yeah ...i just looked it over and i was wrong i read your post then switched to page 2 and read that cheyyene has already done that ...i though i was still on page one and that you posted after him sorry ...i will give you some positive AntiPoints when i spread my Ap's around ....

i made a mistake ..sorry..im human too....

:( sorry i called you an idiot.

cheyenne1212.......I have had a similar problem. (probably everyone has)

It was the AGP video card..not seated properly; even after 5 attempts and changeouts.
It had a 'hook' on the backend that wouldn't fit properly.

Good luck !!

So far ive got to agree with the MoBo idea's. Of course this is simply an opinion based on reading not having the pc in question on my workbench in front of me. Fl34bit3 did bring up a good point about the psu. I would definately check into that. Most of all even if you get frustrated with it dont let it stop you from trying. Just buy cheaper parts ;)

Sometimes if u reverse plug in something the power cable can blow something...i would normally doubt u did that but thats what it sounds like. I know when u reverse some of the p1 or p2 even p7 or p8 connecters u can blow something on the mobo...so i'm assuming u might be able to do it on a IDE cable. Thats what i'd assume...dont think they'res a way to check if u've done it but thats all i can think of.

You could have easily damaged the motherboard when you plugged it in backwards. I guess that is what you get for using an old fashion floppy.

Next time just ditch the floppy completely ;).

Its not an old fashioned floppy, It is brand new.

yes I have already left the floppy unplugged and tried it.

I know its not the Video Card because I've tried two different ones, and I've checked to make sure that they were seated properly.

Good point fl34bit3, I'll check the PS with my meter.

I've never heard of a IDE cable ruining a M/B because its plugged in backwards. But I guess that doens'nt mean its never happened. Sometimes those floppys get me confused on which way to plug the IDE cable into because unlike the HD's, and CD's where the red stripe on the IDE cable faces the Red wire on the Power cable, the power slot on the floppy is on top of the IDE cable, and I forget which way the cable goes.

I know I am grounding my self properly, as I always touch the PS before actually touching a piece of equipment, I also am always touching the it so any static electricity will go throught the PS and not the M/B.

I'm sending the M/B back though, but I will ditch the floppy next time, and check the PS withe my meter before I plug it in again.

Thanks for you help guys. I'll post again and let you know if it works or not. :)

You wont have a mobo to get your psu to turn on and you wont want to risk another mobo to test it. So to test it you will need to short 2 pins on your powersupply that connect directly to your board. I have a diagram. I just got to find it then i will post it.

Edit: k i found the pic i was looking for. Just put a peice of insulated wire between the two pins indicated and your PSU should power up. Im assuming you've got an ATX
power supply though if you have a different one im dont know what pins to short

Well, I was thinking that I would just get my meter and check each wire to make sure its not carrying to much voltage, but I'll try what you've suggested.

btw: it is ATX.

Well you Yeah but you are going to need power to go through it to check them. lol

some old pentium (mostly p2 and AMD k6-2) mobo's use the atx form factor, so if you don't want to use fleabit's short circuit testing technique, you may be able to find an old junker for a few bucks to test the ps on. many a pawn shop or thrift store will have something just like this laying around.

Oh yeah, I wasn't thinking.

was up late last night.

Thanks for waking me up.

Have you sent the Mobo back yet? If not, have you tried what I suggested earlier in the thread about the power supply? Just switch the power supply you have been using with another (if you have one of course) and test on the same mobo. Like I said, I had this happen just the other day, and the power supply was the culprit.

Yeah sorry about that.

I tried a different powersupply that I have been using, and stillhad the same problem.
