Good lord, what the ......

[KickFlip]

ok, i unplugged my comp, used the power cord to power a PSU

which i placed on top of my comp.

I used that PSU to run various DC fans at various voltages, to find out what was too loud for me.

Left it powering the fan for like 2 hours.

Turned off the PSU, unplugged it and plugged the power cord back into my comp.

Hit the power button, and something strange happened.

Nothing came on the monitor, no signal at all.

Lights flashed on the floppy, and CDROM, but no beep from the comp speaker.

The fans turned on as well, but I heard this weird sound, like some moving part was struggling to move and was encountering friction. It made that sound for about 5 seconds then went away.

I figured there are 4 things possibly broken:

AGP card
Mobo
CPU
PSU

If theres anything in this list I missed, please let me know.

So I test everything, and its the mobo thats fried for some reason.

It can't be fried from oc'in, in fact it was underclocked at the time to 933mhz cause I've been stuck with this crap 300W PSU that wouldn't even run my 1g athlon stable.

My only guess is that running that other PSU on top of my comp some how caused some mutual inductance to happen and built up some potential somewhere on the board and fried it when i turned it on.

I dunno, sorry bout the long read, anyone got any ideas,
explanaitions?

Ok well my first thought is that the vid card may not have been connected... If it was trying to read everything then Im not thinking that there is anything serious... possibly.. But check the connection of the monitor... check every possible peice on the inside... Ram - all cards - everything...

And another suggestion.. You might want to move this to the General Hardware section... Odds are the mods will move it if you dont...

Yeah, i pretty much double checked everything.

The monitor works; hooked up another comp to it.

The vid card works; the plugged it another comp.

The psu works; used it another comp.

The CPU works too; used it another comp.

The fact that the bios screen isn't even showing up, actually no video signal whatsoever has got me thinkin its the mobo fried.

Also, when ur comp starts it beeps once.

What does that mean, cause mine doesn't.

And bout movin this post, howda ya do that?

I think that you have to get a mod to do that.

As for the single beep when a mobo boots up, that means that everything's OK, which is obviously not the case for your poor mobo (RIP).

Say, arn't psu's suppost to ground to the chassie/ case?? was the psu you used grounded? you may well have messed up your mobo. Was the fans you were experimenting with in /on the case you were using? I'm no expert, but I'm wondering if some kind of static discharge or stray voltage did you pc in. Sorry I can't help more.......:( ....tr

yea same thing happened to me ( well kinda)

pluged in the computer and the fdd and cdrom would light up but no bios or anything

after like a week of strugling with it i took it back and it turns out

cpu=fried
mobo=fried
vidcard fried
ram was fine ( how i dont know but i still got new ram just incase it was time delay)

( god bless the man who invented warrenties)

I always thought that you puter wouldnot boot up if the mobo was bad because the psu would not get "jumped" and nothing would turn on.

[Tebore]

Possibly one of two things
1. Might be a fried PSU or at least some part or cable of the PSU.
2. Fried MOBO.

I had that same problem awhile back and turns out some part of the PSU was Fried.

[KickFlip]

After deducing it was the mobo, thank God i did more testing on it.

turns out my IDE 0 port is fried for some reason.

If I plug anything into it i get no signal(video)

If nothing is plugged into it everything seems to be working fine.

Whew, thought i was gonna have to save up for a new mobo.

But still, its a mystery why it fried.

?????????????:(

Cool so it woeks fine if you dont plug ne drives into IDE 0?
You can just get a IDE controller if you need it. Hey, its much cheaper than a mobo.
