Intel DX79SI Post Code 00

[ayyEve]

Hey guys,

 

My story is a bit of a weird one. A few days ago i bought this intel board on ebay for $100, it was made clear that there was damage done to the board (scratches on the pcb) but they didn't look to bad to I figured what the heck. (see attached pics for scratches on mobo)

 

The board came in yesterday, and after plugging in just the psu, it would not turn on, which I found a bit odd, but then I plugged my ram and my cpu in and it turned on, so might be a feature of the board? Either way, after setting everything up, it worked flawlessly for the whole day. Today, I went to turn it on and nope... Post code 33. so I restarted it. Post code A9. No beeps for either of them. Now when I try it just doesn't even bother trying, and just sits on 00. I tried removing all but one sticks of ram, all the ram, unplugging some unneeded usb devices, and clearing the cmos, all with no luck.

 

Is there anything else I should try before trying to re-solder the connections on the back? Thanks in advance!

 

My Specs:

Spoiler

Mobo: Intel DX79SI

CPU: Intel i7-3930k

GPU: Nvidia GTX 950 (msi, no 6pin power)

Cooler: Corsair H115i (280 rad)

Ram: 12gb (2x 2gb Ripjaws, 2x 4gb Patriot)

PSU: Corsair CX600M

Drives: Samsung 850 500GB SSD, 3TB WD Drive

Case: NZXT S340 Elite

 

Let me know if theres any other info you need. I will be home later today to test what you guys come up with

Please note though, I do not have another cpu to test, this is my only one, but I have a new board coming in from china eventually (between now and like end of June)

 

Update 1: Removed the mobo from case, checked pins, all seemed good. I also cleaned out the scratches with a parts cleaner (Super Solv Multi-purpose solvent), and I've also tried a different psu and both sets of ram, no luck. at this point i have nothing but the cpu and psu plugged into the board and it just sits at 00, no beeps or anything, but i do find it weird that the (red) standby

LED comes on after a few seconds. I have no idea what to do at this point.

update: with no ram or gpu in it, and after leaving it for a few hours, i turned it on and it showed code A9, so i put the ram and gpu back in, and now its back to 00. im wondering if its my gpu

 

Edit: swapped out the gpu with a 280x, still 00
