Bizarre Motherboard or PSU problem. Any suggestions?

[rapoon]

Product - OCZ 600W PSU & Biostar TP45E

Problem - Occurs when the following actions happen in order: Power off PC, flip switch on back of PSU (to turn off), unplug cable on back of PSU, Press Power Button on PC to discharge stored energy in MB and PSU, plug cable back into PSU, flip switch on back of PSU (to turn on) and finally...turn on PC.

What happens is: Everything lights up and turns on for a split second, then a long 2 - 3 second period of nothing and THEN PC turns on.

I've never heard of or experienced anything like this before.....

I believe that my PSU is failing. Or maybe it's my motherboard. Dunno...that's why I'm here =)

Any suggestions guys? Anyone heard of or experienced this before? If there is a problem...more likely the MB or PSU?

Many thanks!!

PC Specs - Biostar TP45E MB, 4gb Patriot DDR2 1066MHz, E7200, Radeon 4870, Win XP 32.

First question, why are you doing this?
Second question, once the pc boots, is there any strange behavior?
You can try another PSU and/or MB but, I wouldn't borrow trouble.

I have a similar behavior with my system as well, it happends as soon as the overclock profile is turned on in the bios. If the bios remains on the default factory settings, this doesnt happen.

double-post is normal on modern Intel-chipset motherboards. Don't ask me why though. It happens on my Gigabyte P35-chipset mobos too.

And again, why are you doing this procedure? There is no real-world scenario to use it.
