Fried a rig.

Well it wasn't me, it was my girlfriend.

She was shipped a 100% working rig, since I knew better than to be lifetime technical support, heh.

She booted it up and was transferring files, all was well. It was a fairly rock solid stable rig.

So anyway she wants to put her old HD in the new computer. I advised against it since it had a warranty and its best to just not open the case, maybe once the warranty expires.

She does it anyway WITH THE POWER ON.

Thats not the worst part. The old drive was an IDE drive. The computer only has SATA connections on the PSU and MOBO.

So she tries to shove the SATA power cable into the IDE data connector while the power is on and she shorts it. It powers down, and smells like ozone.

It went viral later. Before it happened I refused to touch the new computer. I actually left the room as soon as she started ripping into her new PC saying "I'm out of here before you break something" because she took none of my advice. And 2 hours later I hear panic in the next room.

So her family comes over and tries the new PSU in her old computer, to see if the PSU fried, also frying her old computer. Hours of troubleshooting a PC that was shipped to her in working condition. God.

LOL that is all.

Any advice for troubleshooting a short?

Information about short:

- Polytech PSU 600w (not my choice but was pre-built), fans spin up and seems to work but fried another computer.
- AM3 gigabyte motherboard.
- AMD FX 8000 something (I'm not up on hardware specs anymore)
- G.Skill DDR3 memory had a burn mark on it
- Radeon HD 7850 fan spins at full speed, no error lights
- Error Speaker gives one long continuous beep, with award BIOS
- BIOS cmos was reset to factory defaults by me, before I said to hell with this computer, you fried it in 2 hours flat, and I'm not testing any components in any of my computers also frying them.
- I suspect the 12v was shorted to the 3.3v, feeding 12v to the 3.3v rail, when she tried to jam the SATA power cable into the IDE data pins, hence the burn mark on the memory

I've actually never seen a computer short THIS bad. Any experience here ATGH?

I've had computers ground out on the case and be fine. I've also accidentally shocked a computer with static, but the computer was grounded and so was I, and that computer was also fine. Never anything like this with dead components everywhere. Its like a massacre of RAM, CPUs, PSUs, and GPUs oh god why would you not turn off the power before adding an IDE drive, not that it would have fit anyway.

She dropped ~$1,000 on the build :colbert:

Can somewhere like microcenter test parts witout risking any of my rigs. Because oh man is this rig shorted the **** out. Un*******-believable that someone can short out a working build in such short a time frame as well as their working old computer.

Is the entire build bricked as I suspect?

Absolutely none of her computers will post, and reseating hardware does nothing.

*Looks at OP's user name.*

Hmmm, that story didn't go nearly the way I was expecting given the title!

Anyway, from reading the account, my opinion is that the PSU, mobo, RAM, and CPU on the old rig are most likely toast. I would not touch them with a ten-foot pole. The GPU might be OK, since it doesn't get 3.3V directly from the PSU. The drives (except the one involved in the short) are likely OK.

Ha. "FixBSOD" is replying to "overvolt" about a what to do with a fried computer. :p

This thread really delivers. :awe:

mfenn likely has it right.

That PSU isn't the best. I did a quick search and first review was from Hardware Secrets on a 660W unit, and they said "stay away from this power supply" as their last words. It may not have had the protections against shorting out.

A good reminder that seemingly "simple" tasks for one person might not be so in the hands of the less experienced and "intelligent" in troubleshooting.

I've never used a multimeter myself, but they might be useful here since you can test resistance with them. If the resistance is 0, then you have a short. Also, if this disaster can't be saved by warranty, you could crack open the PSU. BUT DON'T do it until you're sure that voiding the warranty is ok.

I would laugh, but I shorted a $5500 a/v receiver once, so all I can do is nod like a wise man and say "life is an experience."

How did she shove the sata power connector into the molex connector? Did you mean to say that she was using an ide-sata converter on the harddrive?

From what the OP said she put this:
SATA_power_cable.jpg


into the right section of this(not the molex section):
festplatte_ide_anschluss.jpg


with the power on.

Absolutely correct :awe:
She must have a lot of money or good looking for you to put up with it.

All that was needed was an adapter mentioned above and to plug it in when the power was off. Even if it doesn't work, nothing would be damaged.

Amazing, the SATA and IDE connectors are so different how in the world would someone think that was doing to work?. Might be able to salvage the optical drives and possibly the vid card..

/facepalm. Some people should just stick to Apple computers.

Even Apple computers have ports, which could likely prove to be beyond her capabilities at this time.

OverVolt, should this relationship progress, you really ought not be in any hurry to loan her your car anytime soon. . . .

Wow. I built a computer for a friend's daughter. Apparently, it had started blue-screening, so she took it apart and connected the "loose wires" back together. Anyways, she managed to plug a floppy power-connector into a spare USB header on the mobo. And she wondered why it wouldn't turn on anymore. The sad thing is that this girl is interested in computers, but didn't know enough not to plug dis-similar things together.

I replaced the mobo (not at my cost).
