GA-P67A-UD3P-B3 cyclic rebooting

[unkota]

PC:

GA-P67A-UD3P-B3 / Chieftec APS850W / i5 2500K / Palit GTX 580 / 1 TB WD Caviar Blue / Windows 7 64-bit.
Memory: Corsair TW3X4G1333C9A.

None of these components are not OC

I have latest bios F4

The motherboard was bought two month ago with two 2Gb Hynix memory modules and PC started cyclic rebooting right away. I found out the problem was with one of the memory modules. Warranty service checking showed no issues, but I replaced it anyway and PC started working with some random occasional freezes and shutdowns. Linx, Prime95 (12 hour test) and memtest didn’t show any problems. Replacing the PSU didn’t solve the problem, so I replaced both memory modules with Corsair TW3X4G1333C9A 4GB kit
After this everything have been working just fine for two month except the time when I was reinstalling Windows. I found some weird "bug" with motherboard. When I press the reset button on Windows loading screen or POST sreen, PC start cyclic rebooting after POST screen. The only way to stop it was to disable power for the PSU.
Today while playing TF2 I launched AIDa 64 to check graphic card’s temperature. But loading was taking too much time, so I quitted the game and launched Easy Tune 6 and got massive slow down. Then suddenly PC startet stuttering. I could not even move my USB mouse. I thought that the problem with Windows and decided to restart the PC. I rebooted it and went into cyclic rebooting. There was no sound of the speaker. Just a black screen and after 10-15 seconds auto reboot.

It looked as if it's a memory module has broken.
But this is the second memory module is broken on my PC for 2 monts. The first is broken and also worked in same (first) memory slot.. I dont know what was going on, but I think that the problem on the motherboard or CPU.

Hi and welcome to the Gigabyte Forum.

The first thing is I think you have made a mistake on your memory module part number. I think it should be TW3X4G1333C9A. Can you confirm this please as it is very important.

Can you also explain the reasoning behind pressing the reset button when the computer is booting as that can cause a lot of problems. It isn't for playing with.

Sorry for my mistake. Yes it is TW3X4G1333C9A. Thanks you!

I was going to reinstall Windows from DVD and forgot after reboot to enable in the BIOS cdrom as first boot device. So I pressed the reset button to enter the BIOS and got cicrling rebooting.

For your information in future it is easier to just press F12 to choose which boot option you want.

I expect what has happened in this case is that you have corrupted the CMOS by pressing the reset button and so the best thing is to follow these instructions exactly.

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.

I bought the above all at the same time and from that day I have had cycles rebooting issues for 9 months now.

3 months ago I upgraded from XP to Windows 7 & bought a new HD, issues still happens.

Today I bought a new PSU (XFX PRO650W) issue still happens!

So I took out one RAM unit, and it booted into windows but after 3 mins rebooted, then just cycles.

HOW I FIXED IT: its been an 3 hours and its fixed.... ill update post if problem happens again.

I unplugged the >> POWER CORD from the PSU then, >> removed the RAM and CMOS battery, >>plugged power back to PSU >> turned on computer (loud no RAM noise) turned off >> UNPLUGED POWER reistalled RAM >> Got some weired black and yellow screen about BIO not in memory >>  Turn OFF UNPLUGG >> reinstall CMOS battery >> PLUG POWER, start, SET BIOS UP>> WORKS FINE NOW!

If I had only known this 9 months ago...!!! I still think GIGABYTE Motherboards are the BEST and never buy anything else.
