Bizarre boot issue

Lusak · 07-02-2008, 10:39 PM

So I just threw together a new build as follows:

Biostar T45 HP
Conroe E6850
2x 1gb Patriot DDR2 1066
GeForce 8800 GT 512MB PCI-E 2.0 (BFG Tech)
Zalman ZM750-HP 750W power
etc...

Upon powering up the pc:
The display is blank, all fans running. Runs for about 10 seconds before powering off. Seconds later, the system powers back up, runs 10 seconds, powers down. Consistently on the 5th power up, the system runs fine, but gives the predictable: Overclocking has failed, F1 for bios, F2 for default. Selecting the default allows the PC to run flawlessly until it comes time to turn it on again. (No, I'm not overclocking it.)

Upon this occurring, I checked the bios settings and saw nothing out of the ordinary. All bios settings are at default. I am not seeing anything out of the ordinary.

As parts of troubleshooting this, I have:
Reset CMOS (Powered up properly right away following after stating the cmos was reset, but consecutive boots still suffered)

Removed memory, graphics card, hard drive, optical drives, and problem remains

Updated the bios

I was leaning towards a potential issue with the power supply until the cmos reset boots consistently succeeded. Is there anything else I could be missing here, or am I stuck in limbo awaiting word from Biostar?

Any help is appreciated!
