Asus P5B-E odd startup

[Uscooper]

Hey guys i have the asus p5b-e mobo with a core 2 duo e6300. It is at 3.01ghz on air fsb 430, stock voltage, ram is mushkin 6400 at 860mhz2.1v. Everything runs stable and great in the OS but when i turn it on it does that thing where it powers up and then down right away, waits 4 seconds, and boots up fine. Temps at 42idle and about 56 after a long time at full load (but that doesnt seem to have anything to do with this). When i restart the computer it does the same thing, powering down, waiting, turning back on for the restart. I have heard that this is normal after a bios change but now it does it every time. System is 100% stable too. what gives?

I have a similar situation with my P5B deluxe. The sympton you described occurs only if I overclock the system. I suspect it has to do with the power settings in control panel. I would like to know the answer too? Anybody.

yeah i didnt notice it until i went over a certain fsb level when overclocking. I'd like to stress that the system is running excellent, but I just would like to know why it is doing this, and if it is hazardous or not to my hardware. I run @ 3.01ghz 24/7.

i had the same issue and a lots of BSOD the culprit was my crappy 300 psu not the actual one wich is doing what an psu is supposed to do

My P5B Deluxe has the problem no matter if I use a Thermaltake 700 watt quad 12v rail or an Enermax 535w dual 12v rail. Only occurs when I overcock heavily. Either PSU has enough power to power the system handily.

iv got a 650watt antec true power with three 12v rails im not using nearly that much power.

This question has been discussed on ASUS website forums. Maybe a quick search on those forums will turn up the answr. I seem to remember it's the MB causing this to happen, but I can not recall why?
