Hi

Just build a new PC with Z97 Gaming 7, but when powering up it lighten up and the debug  led is runing through a lot of numbers and then it powers down. It takes only a few seconds.

I have measured the voltage on pin JPWR1 an JPWR2 and all the levels are correct.
I have cunsulted the manual for levels on the V-Check connector but I can't find any.
I have measured the voltage on that connector and they are as follows:
Pin1 - VCCIN =1.765V
Pin2 - DDR =1.5V
Pin3 - Core = 0.75V
Pin4 - GFX = 0V
Pin5 - Ring = 0.76V
Pin6 - C_SA =0.9V

I have tried to unplug all the connectors (SSD, HDD, DVD, Fan's etc.) one at a time with no result.
I have tried to set RAM in different positions (got two blocks of 8Gb).
1. Dimm1 and Dimm2
2. Dimm1 and Dimm3
3. Dimm2 and Dimm4
4. Dimm1 (only one block and tried both seperate)

Same result

I took the graphic card out and the WiFi PCIe card - same result.

I took the JPWR2 power plug out and then it didn't power down but of course the CPU is not running then.

Hope someone can help me, please :)

Hi

Are you able to test different power supply? Preferably from Corsair, Seasonic or other trusted brand.

For motherboard powering ports, all has to be connected (8 pin and 24 pin).

Check CPU socket with magnifying glass and bright light, looking for bent pins. Also make sure cooler is correctly attached.

Try on non conductive surface like wooden table or motherboard box.

Thanks

What about the V-check connector. What shall the levels be?
Pin4 - GFX is 0V, that is stange to me :think:

Hi

Sorry. For voltage levels I am not advanced user this far (yet) so I cannot tell..

What CPU do you have? The one you listed isn't valid.

GFX voltage could be the on-chip graphics voltage for the Intel CPU. But if the CPU doesn't have an integrated graphics chip, then it might not have any voltage there. Just a thought.

The GFX voltage will show 0v when you have the graphic card installed. If the debug code LED runs, it should also mean the voltage on the board should be normal. Try switch to the second BIOS. Or try without RAM and see with what debug code causes the power off.

double check all power cables, ensure that everything is plugged correctly

if problem persist:

RAM: Corsair Dominator Platinum 2 x 8 GB
leave 1 memory stick only

SSD: Samsung 850 EVO MZ-75E250 250 GB
remove, disconnect this one


HDD: WD Blue WD10EZEX 1 TB
remove, disconnect this one

DVD-drive: LiteOn IHAS124
remove, disconnect this one

WIFI PCIe card: ASUS PCIe Wireless N
remove, disconnect this one

then retest

if no change:

take out mainboard out of PC case and place it over non conductive surface
then retest again

CPU Cooler: Scythe Shuriken Rev.B SCSK-1100
if still no change:
reseat the CPU and check board for bent pins
also for a test try stock standard cooler CPU instead this one
