GA-X58X-UD7 wont boot after shut down

[gingeralien]

Hi there
I need some help

The board wont start after shut down from windows
I have to switch off power supply for a few
min.s and after I switch the power supply back on.
The board powers up as normal via "onboard / case power button"
but when i shut down from window the problem is back

I have tried
updated bois F3, ran memtest86 for 8 hours "passed 7 runs " ,reset the cmos, changed the battery
,taken the board out of the case to insure it was not shorting and tested again with :one stick of ram
graphics card only, i removed battery for 1 hour put it back in and loaded defaults


every thing is at fail-safe default


Please a advise

Ok Guy's
A new power supply fixed the problem
now using a corsair 1000w
I had a thermaltake 1500w , It worked fine in my last system ,and all the voltage read fine on my multi meter ,

maybe it will help some else
thanks
