I5 + Asus P8P67 does not boot...

[marksl]

Hello everybody, im so freakin desperate right now, as ive been trying the whole day to fix this issue but it just doesnt work..When is push the start button, the system loads up for like 3 seconds (all fans are moving) and then just dies and starts again after few seconds.. and dies again.. and this goes on and on..
here is a short clip i made to show whats its like

you can hear this beep tone in the beginning and the dram led flashing..

well ive tried switching the ram in all possible variations and it didnt help.. removing the battery and clearing the cmos didnt help either..

i dont know, maybe im just that stupid and configured something wrong.. i used the 20+4pin for the motherboard, 2x4pin for the cpu and 8 (using an adapter making 6=8pins) + 6 for the graphic card..

Ive read various topics about people having problems with this mainboard.. either they manage to fix it or have to send it back. Well i hope someone can help me a little bit, im just out of options..

Thanks in advance and sorry for my english!

That adapter for the video card is useless. It probably will not hurt, but it won't do anything for you either.

Work systematically through our standard checklist and troubleshooting thread:
http://www.tomshardware.com/forum/261145-31-read-posting-boot-problems
I mean work through, not just read over it. We spent a lot of time on this. It should find most of the problems.

If not, continue.
The following is an expansion of my troubleshooting tips in the breadboarding link in the "Cannot boot" thread.

I have tested the following beep patterns on Gigabyte, eVGA, and ECS motherboards. Other BIOS' may be different, but they all use a single short beep for a successful POST.

Breadboard - that will help isolate any kind of case problem you might have.
http://www.tomshardware.com/forum/262730-31-breadboarding

Breadboard with just motherboard, CPU & HSF, case speaker, and PSU.

Make sure you plug the CPU power cable in. The system will not boot without it.

I always breadboard a new build. It takes only a few minutes, and you know you are putting good parts in the case once you are finished.

You can turn on the PC by momentarily shorting the two pins that the case power switch goes to. You should hear a series of long, single beeps indicating memory problems. Silence indicates a problem with (in most likely order) the PSU, motherboard, or CPU. Remember, at this time, you do not have a graphics card installed so the load on your PSU will be reduced.

If no beeps:
Running fans and drives and motherboard LED's do not necessarily indicate a good PSU. In the absence of a single short beep, they also do not indicate that the system is booting.

At this point, you can sort of check the PSU. Try to borrow a known good PSU of around 550 - 600 watts. That will power just about any system with a single GPU. If you cannot do that, use a DMM to measure the voltages. Measure between the colored wires and either chassis ground or the black wires. Yellow wires should be 12 volts. Red wires: +5 volts, orange wires: +3.3 volts, blue wire : -12 volts, violet wire: 5 volts always on. Tolerances are +/- 5% except for the -12 volts which is +/- 10%.

The gray wire is really important. It should go from 0 to +5 volts when you turn the PSU on with the case switch. CPU needs this signal to boot.

You can turn on the PSU by completely disconnecting the PSU and using a paperclip or jumper wire to short the green wire to one of the neighboring black wires.

A way that might be easier is to use the main power plug. Working from the back of the plug where the wires come out, use a bare paperclip to short between the green wire and one of the neighboring black wires. That will do the same thing with an installed PSU. It is also an easy way to bypass a questionable case power switch.

This checks the PSU under no load conditions, so it is not completely reliable. But if it can not pass this, it is dead. Then repeat the checks with the PSU plugged into the computer to put a load on the PSU.

If the system beeps:
If it looks like the PSU is good, install a memory stick. Boot. Beep pattern should change to one long and several short beeps indicating a missing graphics card.

Silence, long single beeps, or series of short beeps indicate a problem with the memory. If you get short beeps verify that the memory is in the appropriate motherboard slots.

Insert the video card and connect any necessary PCIe power connectors. Boot. At this point, the system should POST successfully (a single short beep). Notice that you do not need keyboard, mouse, monitor, or drives to successfully POST.
At this point, if the system doesn't work, it's either the video card or an inadequate PSU. Or rarely - the motherboard's PCIe interface.

Now start connecting the rest of the devices starting with the monitor, then keyboard and mouse, then the rest of the devices, testing after each step. It's possible that you can pass the POST with a defective video card. The POST routines can only check the video interface. It cannot check the internal parts of the video card.

like the guy above me posted.

Make sure you plug the CPU power cable in. The system will not boot without it.


(make sure you plug in the main cpu cooler into the White Coated 3 pin connector above the CPU) If you don't the board will shut down and think your CPU is overheating. I know this because i hit delete, for bios and temps kept rising over 80 degrees. Once i swapped the fan connectors to the white coated 3 pin above the CPU cooler it stayed stable.

Hello, thank you very much for this very informative Post. I tried everything out and well it didnt help, so i went to a local pc store today and they checked all the parts.. result: broken mainboard..

Ive got a new one and installed almost everything by now. Though i have one last question, how do i install my graphic card? it has a 8 pin and 6 pin slot. My psu has one 6 pin (named: PCIe) and one 6 + 2 pin (SLI ready)..
Should i connect 6+2 into the first slot and the PCIe one in the second?
