First of all sorry for my bad English I'll try my best to explain my problem.
a few days before I bought these stuff and build a computer by myself for myself:
CPU: AMD Phenom II x4 955 Black Edition
MB: Asus M4A78T-E
Ram: Corsair DDR3 4GB (2x2 GB ) 1333
VGA: MSI R4890-T2D1G OC
Power: Green (785B) (it's a very famous brand in my country and most of the the guys using this brand, and also the one I used I mean Green 785 is a real 780 Wat PSU)
HDD: Seagate 500GB Baracuda (7200.12)
DVD-RW: Samsung 22x
I build the pc and everything works fine the cooling is okay not too much noise, but one strange problem. from every 5 time I push the power button and turning it on, 4 time everything is okay system beep bios screen coming up and then the os start running, but in the 5th time just fans start spinning and nothing else happened I mean no screen and no beep, then I had to push reset button on the case just for one time and the system will beep and everything will be fine again.
first of all I thinked it must be the bios issue so I updated the bios form Asus live update on windows to the latest version, but didn't solve the problem. I also removed the graphic card and test the system with the onboard vga but it didn't worked too. then I removed the ram and cpu and put them back but still have the problem then I checked out for a link between mainboard and my comuter case but there wasn't any link.
The PSU also dosen't have any problem it's cool and work fine and system is totally stable under any kind of pressure. can anyone tell me what is wrong with it? and is it an important problem that I should mention it?
