I recently purchased a RoG Maximus IV GENE-Z, along with an intel Core i5-2500 (locked) cpu. It was to replace a core2duo e7400 2.8GHz on a evga board. My main reason for upgrade was to get a quad core and have the abillity to sli my gtx550ti, that is if I ever want to. Everything is installed properly to my knowledge.
1TB 7,200rpm Hitachi
2x 4GB Gskill sniper DDR3 memory
Nvidia evga GTX-550ti 1GB
Psu: unknown no labels at all but I believe it is somewhere around the 550-700 watt range
Some random LG bluray,dvd-r,cd-r drive.
asus Maximus IV GENE-Z mATX mother board
Upon pressing the power button all fans, caselights, HDDs, gfx cards, and everything that would indicate normal operation comes on. There are some leds that show what an error is if there is one the first two cycle through quickly. "cpu_led" then "dram_led". the next is "VGA_LED" it takes a bit longer maybe 30 seconds before the "boot_device_led" lights up. the Boot_device_led stays lit constantly after that. The computer does not boot, I see no visual changes on my display, and the single "beep" that is usually heard at boot beeps in about 45 second intervals.
There is also two digital numeric led displays for error codes, once the rig reaches the "boot_device_led" they become stuck on B2 which the manual says is "Legacy option rom initialization" it does not change.
My attempts to fix the issue:
remove bios battery
re-seat cpu and ram
no gpu just cpu and 1 dimm of ram in each slot
I desperately need help because I have some CAD files that I need to finish.
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 (standby power supply): 5 volts always on. The green wire should also have 5 volts on it. It should go to 0 volts when you press the case power button (this is also a good way to test the power switch and the associated wiring), then back to 5 volts when you release the case power switch. 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.
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.
Thanks for all the helpful info. I followed all the steps and now I'm sure that its something involving the board itself. I tested my gtx550ti in another build and it works. so the only thing that I can think is the issue would be the motherboard itself, which I purchased 5 days ago.
Yes the HDD is from my old pc build which was running windows vista, if I understand your response correctly does that mean it will not work because it has been used as a bootable windows disk? Do I have to wipe it?
are you using a new hard drive , or is that the one from the old computer with all your data and windows on it?
It wont boot if it is .
Sorry Im Kind of new the the whole pc building thing I have never replaced a motherboard. So Does this mean i must wipe my hdd to be able to boot, because Im not even seeing any video output? Would that be the cause of the issue?
