I read a post here from "Tracker" with almost the EXACT same issue I am having. But I did not see his final resolution the the issue. SOME PLEASE HELP ME ! I orderd a Biostar G31-M7-TE MOTHERBOARD for my new media system. I also bought a new case with a 500 watt powersupply. The board came as a combo with an Intel duel core processor. When I turn it on the first time, the CPU fan and power fan came on, but nothing on the monitor or keyboard. Since I had all my cards and drive connected, I disconnected them and went barebones to see if it would come up. This time, the fans came on for just a second and then went dead. After that, they would not come on at all until I set the jumper to 'clear CMOS'. I was getting nowhere. I called Biostar support, no help, they gave me an RMA to return and GET a new one. The new one arrived. I hooded it up with only the memory, processor. It came on and I was able to turn it off. Then when I tried again.. nothing. it seemed dead. Now I can't imagine two boards being bad. Something else has to be going on. Any ideas? HELP!Replace the board again, and this time try with a new PSU(Power Supply Unit).

You aren't reaching into the computer and touching stuff while it's running are you?This board take the 24 pin power connector. All my other supplies are 20 pin. So I will have to buy a new one to try out another PSU. I have the board out of the case on a static-free mat, so nothing is touch where it shouldn't be. The PSU with the 20 pins did power up the fans, but I still could not turn it off without pulling the cord. Nothing on the monitor. Any other suggestions?If you take your current PSU to a local shop they may be able to test it for you.

I prefer to go to a small local retailer for this, they will usually bend over backwards to get your BUSINESS. Or if the place you bought the motherboard is local you could try there.
