Fried Motherboard OSX's Fault?

[DesolationRow]

Ok. I just thought I'd put this out there, because I couldn't find anything comparable on the forums, but I thought that this might be something we should talk about.

 

I had the Hack up and running (10.5.6) nearly perfectly. Sleep wasn't working, but everything else was. So I decided to boot my old iMac up in target disk mode to transfer my stuffs to the new one. A minute or so into the copy, my hack just up and quits. Self-shutoff. I booted her back up, and almost immediately after booting OSX, it quit again. From thenceforth, it wouldn't turn on. Pushing the power button would cause the LEDs to flash and the fans to spin for a quarter second, but then it would die again. No beep codes, no BIOS. Nothing.

 

My first thought was that my PSU had gone, but it tested fine. Just to be sure, I installed a new one, but the same symptoms.

 

Was it the firewire that fried the board? I'd used the firewire to transfer a couple gigs of stuff off my external drive, but maybe target disk mode (using the iMac as an external drive) is too much? Or did I just get a lemon of a motherboard? Or is the motherboard possibly not the problem, and it's something I haven't even tried?

 

I RMAed the Mobo, but is there anything I need to worry about when it comes to installing the new one? I'd hate to have this be my fault and I'm just blowing through mobos like an Albuquerque hooker through cheap yeyo.

 

Any thoughts?

 

Build:

Intel Q6600@2.4 (stock)

GA-EP45-UD3R rev. 1.1

Radeon HD 3650 512MB

2x2GB OCZ Fatality

2x640GB WD Caviar Black

LG DVD-RAM

Vista Ultimate 64

OSX 10.5.6 (Vanilla Kernel, a couple of kexts for video card, etc.)

 

Thanks, fellas. Sorry for the long post. I bow to your expertise.

My first guess would be the iMac's FireWire fried your mobo - I remember a while back there were some FireWire hubs IIRC getting fried by Mac Pros and iMacs.

 

Maybe something unusual in the way PC mobos being used as a FireWire HDD that kill ones with certain FireWire chipsets.

 

I thankfully have no need of FireWire on my Hack.

Mmmm.. Bummer. I guess I'll have to do the longer process of transferring stuffs to the external drive, then back to the new mac. Hope nothing I have is >4GB.

 

Is this something people have heard of, before? I can't find any google references to Target Disk Mode being any different from any other external HDD.

And I just found this thread from more than a year ago:

This gent was using a similar mobo to mine, and had the exact same situation (connected to another mac via Target Disk Mode). Is this a possible recurring problem, or did he and I both get lemon mobos that couldn't handle firewire stuffs? (Although I had used firewire with mine and an external HD before the catastrophic incident).

 

Edit: And another case, also involving Target Disk Mode:

Congrats to me too lol

Just burned, actually my friend did, perfectly working Gigabyte GA-EP45-UD30 ver 1.6. The funny thing is I can't find one to replace not even on ebay.

It was unbelievable. This friend of mine stops over with his G5 and plugs the firewire from his G5 in my front firewire input and both computers shut down.

His still powered on but my hack is dead.

After reading this post and this one too, I suspect the board is damaged.

I get a QUICK flash of the 6 Phase LED indicators and that's about it.

I hope the CPU is still ok and i will be replacing with this mobo probably.

 

NEVER CONNECT DIRECT FIREWIRE FROM REAL MACS to your HACKINTOSH!
