hi
i am one of the stupidest people ever! i brought a new 56x cdrom. i pluged it in, WHEN the computer was on. i tryed to push the power connecter in, but i think i tryed to push it in the wrong way. i heard a loud bang, and windows crashed. i turned it off, and on again, but it wont boot. it starts up, all fans go, but it dont go into the bios, or go past it. have i completly screwed up my computer?
thanks
(dont go on about who stupid i am, doing it wen the computer was on please! I NO!!)

How can you plug a molex power connector backwards? It is keyed. Is it an external CD ROM? As you know that you should never do what you did,it does not sound good at all. I would recommend taking it to someone and having them check it out. With any luck, it may be only the power supply. There are way to many factors that it could be at this point due to what you did.

I would say yes. But it is hard to tell. I dont know exactly what happened, but, chances are... yes. I think you might have screwed your boot section. Which is the thing that allows your comp to turn on.
If I were you, I would have a technician look at it, and get his advice. But installing a CD-RW when its on? heheh :)

One of two things happened. If you got lucky you only corrupted the BIOS and this can be repaired. If not so lucky, you blew the motherboard too... and quite possibly the explosion took out the hard drive too.

i think the pins just touched wen i tryed to put it on backwards. what are the odds it would be the power supply? the only thing what makes me think that isnt, is that all the fns, that use molex connecters, are working.

Very slim, but possible.
Again I would recommend taking it somewhere. They would have the tools to really check it out.When all else fails beat the $%!* out of it!!!

It is not the power supply. As you say the fans wouldn't run if it was... and be glad of that. I've seen a power supply go. Not a pretty sight and makes a mess of the board and drives too.

There still could be a problem with it though when it takes a hit like that

i have just found out my computer is under worrenty still!!! if i take it to the shop, should they replace what is broken?

They will know right away what happened probably. Obviously, do not tell them you did that if you plan on trying it. FYI if they find out, your warrnty is null and void for anything.

thanks everyone for all your help (angrymen2001). the thing what is wierd, the fans spin, but i cant eject the 2 cdrom drives. is it because fans dont use hardly any power, but cdroms do??

You are probably not getting power to them. You can manually open them if need be. In the front you will see a little pin hole somewhere. Straighten a paper clip out and gently prod around. By pushing in a little button in there it will open the CD Rom enough to manually pull it out the remainder to get at CD.

thanks angrymen2001. i think i am going to borrow a psu off me friend. i will keep you posted wen i find out. thanks again!

"what are the odds it would be the power supply?"
99%. The question is whether the mobo is also kaput. The fans run and the cd-eject doesn't because the psu is just limping along, or because one wire set is intact and the other isn't. Switch the molex that goes to the fans with the ones that go to the cd.
"if i take it to the shop, should they replace what is broken?"
they will not be able to tell what you did. "Should they replace" is up to you. "Will they replace" is not in doubt.
Since this post disagrees with some of the posts above, you may be inclined to believe the earlier posts. So pretend this post was first and then re-read the thread. Gives you some extra objectivity.

right. a bit more info. the power light is not stayin on, but the loading light is. anything there wot is a help?

the power light doesn't stay on but the loading light does, this is not normal for my computer

(Switch the molex that goes to the fans with the ones that go to the cd.)
I done that with no luck.
i hopefully am going to borrow my mates psu and try that. keep my fingers crossed! is there any other way to see if my psu is blown???
also, i tryed clearing my bios. no luck. how do i repair a currupted bios?? i cant flash it, because i cant get past the bios to do it!

there is no evidence here of a corrupted bios
Trying another psu is the best next step. Do not plug that psu into the hard drive, cd drive, floppy, dvd, etc. Only plug it into the mobo and fans. See if you can post and get into bios. If so, plug in everything and it should boot to windows.
If it does not go into bios, and you are sure the mobo, memory, vid card and keyboard are plugged in correctly, you should assume that you have blown your mobo. It is even possible that your original psu is okay and its only the mobo that is blown, but that's pretty unlikely. But neverthess here is a power supply tester

I'm imagining that this thread was created by two roommates each with the name barb.

Before you swap out (powersupply) PSU's try this:
0. Push the power button and hold it in for about 90 seconds to discharge the capacitors on the motheroard.
1. Remove the CMOS battery, disconnect all cables on the board, especially the main power connector to the board and all other molex connectors too.
2. If you look @ the back of the powersupply you will notice a (red) voltage selector set on 115v, disconnect the AC cord, flip it back and forth a few times (say 5-6) and set it back on 115v; plug in the power cord back and all motherboard cables and CMOS battery then turn the PC on and see what happens.
Let me know how that goes.

thanks johnoh! i will keep you posted tomorrow, thats wen i am getting my mates psu. thanks again

@ this point looks like you are going to need a new PSU unless someone else has something that has not been covered yet.

The greatest risk is not taking one

I think the mobo is blown, a friend of mine attempted to take out, and reinstall his sound card while the PC was still on!, according to him, the computer was still working after he re-inserted the card, however after a restart, it would only boot to post saying that "The CMOS has been cleared, please restart your computer" and the hit F1 for setup was there, however, he couldn't get into the BIOS, according to him, his fans were spinning, as well, (But he didn't blow the PSU, all the drives were still getting power, from what he says)... I think its time for you to buy a new PC.

If you plugged that power in reverse it would short out a cap, or a diode in the power supply, OR the cdrom itself. The fans will still run because the power supply is designed that way, they have several rails in them. To give you an example if you ever have a comport (like comm 1 ) that does not work it can be the power supply that is the cause,I Have seen it for MANY years. That is where you herd that snap or bang sound. Take the power supply out and take the cover off and start looking in it you will see either paper all over (from a cap) or you will see black chucks in it. So I would start with a P/S and go from there, But WITHOUT hooking up that cdrom drive first. Because if that is shorted it will take out that new P/S. You could also check the power rails from your P/S if you have a (VOM) volt ohm meter. Check for amp draw and volts at the source and then you would know. Red wire 5 volt, Yellow 12 Volt, Black Ground. But the question is how many components have you got running in you computer and the amp draw.? Harddrives 1 or 2 or 3 or 4.? What is the rating on your P/S. If and when you do buy a new P/S make sure you look at the AMPs because you can buy a 400 watts P/S with LOW amps, So make sure you get a higher amp P/S when you do buy one. There IS a difference in the price and the amps. Take care, and as always if unsure seek someone who knows, "NOT" someone who thinks they know. Because friends will always try to help even if they don't know, Not that its a bad thing but sometimes not a good thing.

Have you removed the hard drive to see if it will at least say, “Hard drive not found”?
I hooked a power connector backwards to a hard drive once while it was running, yes it can be done, you can't insert it fully but it will go in just enough to make contact.
You should have seen the chip fly of the bottom of that drive! Thankfully it was an old 1GB that I didn’t care about.And I didn’t learn my lesson ether! I later hooked a CD-RW drive backwards, the motherboard started smoking from the bottom (near the BIOS chip), and sparks were coming from the back of the drive!
Few! That shook me up quite a bit! The weird thing is the computer was fine! It wouldn’t boot at first but I waited a few minutes and then it did for some reason.And since I almost fried my BIOS, I’m thinking maybe you DID fry yours.

Dont worry you are not the only fool in the world. I too did this to my computer but was good enough to get it back into working condition though i screwed up my CD drive.Try this may be it will help.
Remove the power supply of you PC and then remove the BIOS battery. This should reset the bios if there is something of it left. Then try to boot you PC. Though take my word your CD drive wont work.

You are a fool, but I like fools, -I'm one of them! Just look at my homepage to see that i'm pretty insane to have rebuilt my brand-new Dell in that case! I'll be paying for it for two years!!! The Mobo fried because it didn't fit in the case right, so I slapped an ASRock in there and an Aero 4 lite with Arctic Silver 5, now its not a Dell at all and talking to Indians and Chinese (Dells punishing Tech support) is worthless ( Like it wasn't already) Good thing is, the mobo is pretty and much more OC-worthy AMI BIOS, it is very pretty. http://www.freewebs.com/kkupdate3/
If you want to do the right thing, RMA and get your money back, act like the avarage stupid customer so they aren't suspicious. Why buy piece-after-piece through trial & error when they can backup your HDD in a new exchange system all for free.
