Got a used board that was suppose to be all good last week. dropped in a 3770k that had been working when my old board died due to a leaking CMOS battery, as well as 4 x 4gb sticks of Corsair Vengance DDR3. got nothing when pressing the power button. tried jumping the power supply on, still nothing. power supply is/was a 6 year old AX750 Corsair unit that had been working flawlessly. wait a week, aquire a new Corsair 650 unit. try again, still nothing. strip it down to it simplest form: 3770k with OEM cooler, single stick of DDR3 and still nothing. try with just the 24pin ATX power connector, and it will spin up the CPU for about 30secs at a time, however i get no video output, so no idea if its booting, but i suspect not. the moment i plug in the 8pin connector it will shut off and not turn back on.

Anyone have any ideas? could a bad CPU cause it to not power up at all if the EATX power is supplied? i would think those circuits would be isolated via the VRMs and power phasing. Don't really want to push the seller on a return if there is any chance i am doing something wrong here. unfortunately, i really don't have any way of testing this CPU.
 
Hmm, you make sure the clear cmos jumper is set correctly? I had a board that showed the same symptoms. Found out the Cmos jumper was still set to clear Cmos/Bios. Once I set the jumper to the correct setting, board booted right up.
 
Going to ask some local friends if anyone has a board or chip I can test with, then probably have to go that route.
 
Sounds like a dead board to me. A shame too because that's a pretty good mATX Z77 option.
 
Did you double check how the board is mounted to the case, and all the spacers are properly on the case?

I've seen "shorts" due to board installation, even happened to me on my 2nd rig build a long time ago!
 
Clear on the tray, but have also been tested on cardboard covering a wood workbench, for just that reason.

I'm leaning towards a dead chip instead of the board. Seller confirmed the board was fully operational when he sold it to you, so that rules out the board. And I'm sure with your experience with pc hardware you didn't kill it/damage it.

I'm in NY so I'm sure I'm too far away from you test the parts with my 2500K setup.

If the Celeron boots then that would point to the problem being your 3770K, unfortunately, you don't really know the Celeron you are waiting on is fully functional either. If it doesn't boot you still can't rule out the board at being the culprit...unless you have some way of confirming the Celeron is working.

You might find yourself still needing a second board to confirm whether or not the CPUs work. If that turns out to be the case perhaps a PC repair shop in your area might be able to test them for a reasonable fee.
 
Been trying to find someone/someplace local with a known good chip and board to test against, and not having a lot of luck. Still working on it. I really hope the Celeron boots though, I really don't want to have to deal with a dead board and a seller that swore it worked when it shipped. It's fucked situation for everyone. I'd honestly rather find out my 3770k is fucked than the board at this point.
 
Hopefully you'll be able to get it sorted out when the Celeron arrives. Without a doubt it is tough to trouble shoot when you don't have available parts to swap in and out.

That said, reading thru your OP once again, it seems unlikely to me that a leaking CMOS battery in the original M/B would have damaged your CPU (3770K) so I have my doubts about the replacement motherboard. It is entirely possible that it worked when the guy shipped it, but somehow got damaged in transit.

I am interested in knowing what you end up determining to be the problem so please do share your findings.
 
Wanted to chime in here. As the seller of the P8Z77-M PRO motherboard I wanted to put aside any doubt that the board was, is and has always been in perfect working order. I take exceptional care of my gear, kept in spotless condition. I had it up and running in an i5-3570K system for several weeks up until the day I shipped it to Nimisys.

Thanks for your input, mothman, and please do note that when I questioned the functionality of the motherboard I stated the board could very well have been working when shipped, but somehow got damaged in transit, so in no way was I trying to imply that the Seller (now self-identified to be you) intentionally sold a non-functioning motherboard as fully-functioning.

I have personally sold and shipped a fully-tested, functioning motherboard that when it was received the audio no longer worked. I have no explanation for how it happened, but it could have only occurred during the transit, or it was damaged by the Buyer. Given that it was an experienced buyer that I completely trusted, the latter was unlikely, although granted, not impossible. There is, of course, a third possibility, and that is that I unknowingly damaged it when doing the final disassembly after testing it. As careful as I try to be, it can not be denied that the probability, however low, does exist.

Troubleshooting electronic components can be frustrating & perplexing at times, so I am very curious in seeing how this all turns out.
 
So the $4 Celeron showed up, tossed it in and no change. Fuck. now i got to try to find another damn board to prove out both chips, the ram sticks and power supplies.
 
Well, that's not what we were hoping to hear.

Just curious...and admittedly, grasping at straws here (and in no particular order).

(a) When trying a single DDR3 module, did you happen to check the manual to be sure that you were using the correct slot on that particular motherboard for a single module? And if so, did you rotate thru the four modules to test them all, or just use one and call it a day?

(b) You indicated that you tried jumping the original PSU...did you try jumping the replacement? You said it spins the CPU for about 30 seconds...does it go into a loop of shutting off and turning on, or just shut off after those 30 seconds? If you haven't tried jumping it, maybe attach a fan to a connector and see what it does. Won't guarantee the PSU is good, but at least you'll know it will power on and run a fan.

(c) Have you inspected the mobo socket for any bent, or missing pins?

(d) Completely clear CMOS on the replacement motherboard (unplugging PSU and following the steps in the manual)?

As the original owner and seller of the board I can confirm that the motherboard had no "Bent or missing pins", or any other issues at the time it shipped to Nimisys. It was very well packed and no evidence of shipping damage was reported to me. At this point having no idea what the board has been through in the hands of the Op I recuse myself of any responsibility for it's ultimate disposition. End of story.

Tried populating all 4 slots, then A1+ B1 and A2 + B2 with the a couple of stick combinations (d1+d2, d3+d4, d1+d4, d2+d3) then finally rotated all 4 sticks through A2, per the manual as the preferred slot for single DIMM operation.

Jumped the second PSU as well because it won't power on if the EATX connector is attached to the Mobo. it will run a D5 pump as well as a fan controller with 4 fans attached just fine if jumped on and not connected to the motherboard. I am not 100% convinced the first PSU is dead, but due to age and the symptoms I am content with the purchase of the replacement. when the 24 pin ATX connector plugged in and the 8 pin EATX connector not, the Celeron it doesn't loop, it will power on for about a second and then stops, with the 3770k it power for 30 seconds then cuts off and loops. with both power connector seated into the motherboard it won't power. period. not via the PS switch header or manually triggering the PSU.

looked over the board, no obvious signs of damage. didn't pull chipset or VRM heatsinks because if i have to force a return via PayPal, i'd rather not have to prove i didn't damage anything by doing so.

cleared cmos, very first thing i did was actually put in a new CMOS battery, just because i had no idea how old the one that came in it was, and i didn't want a repeat of a failed battery.

though thinking about it, i need to retest with the Celeron one more time with a discrete video card. didn't think about it yesterday as the 3770k has an iGPU and that isn't needed, but i didn't check whether or not the celeron has one. according to Intel Ark it has one: https://ark.intel.com/products/53414/Intel-Celeron-Processor-G530-2M-Cache-2_40-GHz but i rather check just to be sure.
 
Well it certainly sounds like you had already addressed the items I mentioned.

While it wouldn't hurt to test with a discreet card, shouldn't the system boot regardless of whether or not you could see anything on a monitor?
 
honestly it has been soo long since i had a cpu without an iGPU, i don't remember 100% if they boot without a discrete card and no iGPU. shouldn't matter in this case, but because i don't have a second board to test both the Celeron and 3770K on, i don't know 100% that the iGPU in the Celeron, or even it, works.

If they don't work, you should be able to reset the bios and the iGPU will work then.
 
Still no go with the Celeron and a video card. I was able however to find a working Q77 board at the local JC. Popped in my memory, both the 3770k and Celeron... All powered and booted to windows... Not looking forward to finding another Z77 board and what comes next

I can't see anything wrong physically with the board Nimisys. Extremely odd. From what I gather, maybe the board fell victim to shipping damage or the Gremlins did something to it :unsure:

I'm very sure the seller took great care in packaging the board for it's journey to you, but you know how shipping staff is.

Maybe RMA?
 
i know it's odd, and the seller did send it enclosed in an anti-static bag, no physical damage to the shipping box either. no reason to think it would not work.

It's like trying to solve the rubiks cube puzzle. One of life's many mysteries.
 
Quick update:

i shipped the board back to the seller, and thanks to some gentle prodding from a friendly local admin, i finally heard back from him today.

From the PM
"Here's pics of me opening the board and examining it for damage. I discovered the likely problem, a cluster of scraped traces very near one of the mounting holes, leading me to believe carelessness is the reason the board didn't function in his possession. Those scraped traces 'WERE NOT THERE' when I tested and shipped the board"

the image supplied: https://i.imgur.com/0a4I3Vg.jpg

My tray uses a plastic christmas tree like support for that position, but looking real close at the picture i took before shipping it back i can see the same marks. i did not look that closely prior to first installing the board, so i really can't speak with authority whether or not they were there or not when i got the board.

i will say this, given that area is under the audio jacks, had i seen it, i would have still tried the board. possibly a bad audio port, but not something i would think would stop a board from booting.

perhaps i am wrong?
