Question about Biostar NF325-A7 Motherboard
Help! when i plug the power cord to the power supply, the cpu automatically run itself, but the screen is just blank and no beep sound. the reset button seems to failed it self. the cpu cannot be shutted down, cannot be reset.. just blank.. at first i thought the power supply problems, but i have already swap to new one, but it seems to be just the same. memory and vga card has already being tested also and both are just working fine. anyone on this please?! -_-;;;; thank you
I can create this by unplugging my CMOS jumper or having it plugged into the reset jumpers. So this could be your problem if you fiddled with it. Also another thing it could be. If you put a processor that physically fit the board but wasn't supported by the board. It would do this. Probably other possiblities too. But these are my experiences

Well, I'm a young Mexican Eng. I was having exactly the same problem, after trying different things, I came to the conclusion that the problem was in the motherboard, I connected the auxiliary power supplies, one of 4 pins and the other of 6 pins, I turn manually the power source, may be you ask, how? well living the 20 pin connector out of the motherboard I just bridged the green and the gray cables and it turn on and the pc started!! relaying in the auxiliary power supplies it worked, but may problem was that one of the sector (don't know which one, doesn't work with the 20 pin connector connected) May be this would help other, it worked for me.

Was there any work or upgrading done before this problem? If not follow your power button wires (some pc's have2 buttons power and reset, check both)to your motherboard, then disconnect them. Turn your pc on to see if your pc turns on by it self. If not then test your power button with a multimeter. if your pc turns on without your power button connected then other problems could be motherboard related if wires on back of pc were pulled accidently.

There should be a little red or black switch in the back of your power supply. see if there is one, and then if there is, turn power off, and swtich it to opposite settings. this should help...at least i hope so.

I have the exact same problem as the first guy stated, when I turn on my computer it starts up, but the screen is just black and no beeps from the motherboard. I'm guessing my motherboard is dead. *No beeping whether or not the keyboard is plugged in. But since the screen is black and not showing the color thing like when the monitor has power but is not plugged in, I didnt think that it was the motherboard, but still there are no beeps. *The post code(hex) displayed on the motherboard itself if FF.
Any suggestions to try and fix this motherboard
Is there any hope!?
p.s. I have 2 other these and they both did the same thing.

A best way to solve this problem is insert the os version and set to repair in the msdos prompt run chkdsk do not run in safemode command prompt it wont work

I personally think this is a complex technical problem like a faulty component that has to be repaired by the manufactures.Or that a technician has to replace some chip on the motherboard. I have tried applying thermal compound but there was no change.

Check to see that the CPU is currently seated properly. Also, check to see that there's no too little and not too much thermal compound on the cpu. The compound should only be enough to cover the core, and if it's getting on the bridges of the CPU, it can cause issues like this.
