Dead motherboard or CPU?

[NecroFlex]

Ok so i just got an X58 mobo with an i7-920. Owner said it was broken (got it for 5€, for fun), so i try a few things, everything lights up, lights go away, few seconds later it shuts down and then restarts and continues that.

 

At this point you'd think it was the mobo being dead, but i put a speaker in it and decided to remove the ram and boot it up, it beeped. From what i know if the mobo was dead, it wouldn't beep that the memory was missing.

Thoughts?

 

P.S. i smelled something burning, like a wire, but it wasn't there when i removed the power button connector and the 1st speaker i put in (tried w/o the speaker first, then speaker, sudden bad smell, removed the speaker and the power button cable, then after a few more tries w/o a smell i put in a new speaker, was fine), but doesn't seem that there's anything wrong with the mobo in that regard. Speaker might have shorted

Have you tried removing the CMOS battery?

That burning smell was probably the final bang. The CPU might still be ok though. Try moving some ram around. Make sure that there is nothing on the board, like small metal deposits. Disconnect everything aside from the fans and display cable, and use a screwdriver to jump the power button pins, it may be a short from something out side of the board.

The board wasn't working in the 1st place so the burning smell wasn't the board.

 

Anyway, got a xeon to test it out, E5506, board powers on for a second and then powers off, keeps doing that, so the CPU probably isn't supported?

Asus say its supported. My money is on that there is something in the socket or on of the pins are bent.

MSI X58 Platinum

 

Only Xeon officially supported is the W3520

Look on the board for any traces that may have been broken with a scratch. I had a dead board, found out the PO has broken a couple traces when trying to remove the board so I whipped out the soldering iron, scratched away part of each trace to expose some copper, soldered a wire to reconnect it, tested that the connection worked with a voltohmmeter, then secured the wires in place with some epoxy. It's ugly as sin but now I have a working system built with an 8320, mobo, and 16GB RAM for $75.

Checked...there kinda was a  trace that...i kinda had to pull off, probably the one that made the smell, it's where the LAN/Sound traces are, from what i see it doesnt' connect to anything, 2 empty parts, probably made for higher end boards. Saw a few more scratches but they don't seem to be deep or anything.

 

The CPU socket tho, CPU is in well and all, the metal around moves even tho it's screwed down but the issue is i really need to push down to secure the retaining pin down, idk why, feels like it's too much force.

 

Still doesn't POST, constant loop  oh well

 

EDIT: the south bridge is insanely hot tho, could be the issue
