Biostar TA790GXBE board has stopped powering up
Posted 24 September 2012 - 12:43 PM
I've just tested it with only the CPU and RAM and when pressing the power button (connected to the header, there's no on-board buttons) the PSU and CPU fans spin up for a couple of seconds but then spin down again.
It seems like it's tripping out for some reason. I don't think there's any problem with the CPU or RAM as I've been using them on another board, so I wonder if there's an issue with the PSU but I tested that with another board a few weeks ago and that was fine, so I don't really know what's up.

I haven't read the whole thread so maybe this was mentioned? The fans will will run full-throttle then "settle down" until needed at higher temperatures. It's called "Smart Fan" and usually you can turn this ON/OFF in the BIOS somewhere.
This is normal (if it has Smart Fan) and a word of warning - I have a "monitor" software installed and it wreaks havoc if you set the Sensors-ID on the wrong Sensor (mine has 3).

I did actually have it open recently as I needed to replace the fan which had started making annoying noises intermittently (probably the bearings were going) so I cleaned it out then and didn't notice any bulging caps. I just tested it by shorting PS_ON to GND and it stays on like that but as you say, it may have a fault that's causing it to trip out when it's under load.
I think I'll have to try my Antec PSU from my main system and see if that works with this board.
