I just installed this motherboard in a new system this week. I'm using a i5-2500k processor, 8 GB Gskill 1600 ram, and an EVGA 460 GTX 1G Superclocked. Also using an OCZ 500w PS. I installed everything all it all worked fine but Windows 7 was stalling while extracting files. I tried a whole host of things as per the Windows 7 support forums. None of their options worked and the last thing I tried, as per their suggestions, was disabling Legacy USB support. I did that and from that point on the motherboard wouldn't post. It would turn on, display the logo screen, and then reboot.
I have tried swapping out different memory configurations, removed all drives, even tried a 700w PS thinking I might be too low. Nothing worked. This morning I read about booting up the dual bios and it booted right up. What are my options from here. I can get into the bios when using the dual bios but as soon as I reboot im back to square one. So what can I do from here?
Thanks,
Mike

Also forgot to mention that I tried all the suggestions from this thread: http://forum.giga-byte.co.uk/index.php?topic=6264.0
I did an extended CMOS clear yesterday for approximately 7 hours. No change.

Hi
Well I would check to see what BIOS version it is that boots alright and then synchronise both BIOSes to that version. That way at least if the BIOS reverts to the other one it will be the same.
Are you running the laterst BIOS version available ?
-
The one that boots alright is only F3. I can update them to the newest. How do I synchronize them?
-
Hi there,
To synchronise the two BIOS chips so that they contain the same version you need to press the "Alt & F12" keys simultaneously in the same manner that you would press the "Del" key to get into BIOS.
It can take a couple of attempts at starting the PC and pressing the two keys before it registers and when it does, you will get a message about flashing the Main BIOS to the Back-up chip. Do not press any buttons or power down the PC until after the flash has completed.
You can check which BIOS versions are being held in both chips by pressing the "F9" key on the BIOS homescreen.
-
THanks, im going to try that right now. I can't normally get into my bios with a normal boot. The only time I can get into the bios is when I boot straight into the secondary. If this doesn't work from a normal boot what will happen if I do Alt & F12 when booting as I would for the dual bios?
-
Hi again,
not sure to be honest but as I said you might have to try several times before the keys are recognised and the back-up BIOS flash will occur.
-
If you manage to synchronise the two BIOSes with the correct version then hopefully you shouldn't have any more trouble with booting any more as they will both be the same as your Backup BIOS.
-
Well unfortunately I have a new problem this morning. Now the power just keeps cycling. It turns on for about 2 seconds, then off for about 5, then on again for 2, etc. No post, no beeps, no nothing. I'm about to take everything out of the case to test to make sure something isn't shorting.
-
The other thing to check if there is no short is that the cooler is making a good connection to the CPU. Because what you are describing is the same as you will get from an overheating CPU. If you are using the stock cooler it is quite common for it to come loose on one of the stanchions.
-
Hi again,
There is of course the possibility of a short in the system, either from an extra motherboard standoff under the board and also from where the motherboard sits against the backplate.
Any chance of a full list of your components as this could help with further troubleshooting for you?

The Hard Drive is a 1TB Seagate from another system and the DVD Drive also came from that system.
-
If you remove the PC from the case and find you still have the same issue, have you got a different Graphics card that you could try?
I encountered a problem (on a different system) with similar symptoms and found that the higher spec'd GPU was the cause.
-
Another thing that is easy to try is remove one stick of memory and try booting. If it fails try the other stick in the first slot preferably.
-
I removed it from the case to eliminate the issue of a short. I reseated the CPU cooler and made sure it had plenty of thermal paste which it did. I tried different ram configurations, different power supply, and put in a Nvidia 6800 GTS card. None of that had any change. CPU cycles on for 2 seconds, off for about 5, then repeats.
-
In that case I think the next thing to try is to clear the CMOS.
Remove the power cable from the mains supply and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors.
Once done remove the motherboard battery for at least one hour before replacing it.
Next plug back into the mains supply and boot.
You will now need to enter the BIOS by pressing DEL and load Optimised BIOS Defaults.
Make any other changes to the BIOS settings to suit your self like disabling the floppy drive, disabling the full screen logo and making the HDD the primary boot device and then press F10 to save and exit.
-
Well I tried clearing the Cmos. I left the battery out for approximately 4 hours. Its still doing the same thing. Powers on for about 2 seconds and then cycles. Never makes it to post, no way to get into bios.
-
It would be worth checking for bent pins on the CPU socket also.
Take all the usual anti-static precautions.
Very carefully remove the heatsink and fan. Probably a slight twisting motion is best to release the two as the thermal paste can act like a glue.
Once off remove the CPU taking extreme care both physically and electrically(static) and place somewhere safe.
Make sure that the lighting is very good and even.
Now scrutinise the socket for any pins that are out of alignment, even slightly.
If in any doubt whatsoever take a couple of macro (close up) photos of the socket and post them on here for us to check.
Also look at the bottom of the CPU at the lands (little copper circles) and make sure that there is a mark in each somewhere near the centre.
If there are any missing marks or any of the pins are obviously bent then that is your problem.
Before refitting the CPU clean off all residue of the old thermal paste and the same on the heatsink and then apply a small amount (about the size of a grain of rice) to the centre of the CPU once it is inserted in the socket.
-
I checked the CPU. No bent pins. I didn't really expect there to be since it was once posting and beginning to install Win 7. The CPU had never been removed. I did clean both the cpu and heat sink and then reapply thermal paste. No luck there either. I have my RMA # from newegg and I think at this point i'm just going to ship it monday unless you have any other ideas.
-
No I think tha\t is quite a good idea at this juncture. At least when you get the new board you can be fairly certain it will be working alright and if there is still a problem at least we have a start point. Please just let us know when you get it back and how it all goes.
-
I will do, thanks for all the help.
-
The new motherboard arrived today and everything works fine.
-
Oh! Great! At least we did make the right choice then and good news that it is all working now. ;)
-
Yep, everything is installed now and working great. Thanks again for the help.
