P4SD - case I7M
Hello all.
I recieved this board monday and i cant figure out what is wrong with it.
even before recapping, the caps it had looked good (IM noob O) but still since i finally got some caps (crappy but still caps, and thats all i could manage to get around here) i decided to try out.
the board keeps shutting down abruptly, sometimes it takes longer, sometimes it wont go after the first bootup screen....
i found a pattern: it last longer (or sometimes not even fail) if i physically leave it in its laying down position and not on its standing positiong. Does that make any sense? I cant find nothing wrong with the board, I recapped it and still doing the same, one of those days i left it running mprime laying down and it was working morning after, another day i tried it with mtest and the same... but if i leave it on its standing position i dont even have to wait much when it shuts down, the longest it takes to shut down is about half hour... at once this morning it sent me the PSU error, i changed PSU and it was really weird (i dont know if it was a misconnection but i didnt see any) the board would just not advance to its next booting screen or if did itd get stuck right there (not shutting down, but gettting froze, not responding to caps/num lock) then i put back the original PSU and began working again (WTF?)
then the last times i tried on mprime i realized mprime would say someething like:
"hub 1-0:1.0: overcurrent change on port 7econds" <- (is not a typo, thats how it was shoing up)....
does any1 have an idea what could this mean? the board had one usb stick memory on one front connector (the one i was booting with) and a usb mouse in the back, ps2 keyb and vga monitor.
these pics are how the board currently looks like. i havent manually resolder the whole board, also have not applied hot air to it. do you advise any?
i have changed: CPU, cooler+fan, GMCH cooler, DIMMs, PSU and almost fully recapped. (even the rubycon besides the memory bank is recapped, i pulled it from a dead board.) the only caps i havent touched are those in the CPU area (1800/6.3) and the few polys the boards got. the only area i resolder was the area arund the GMCH.
Any tip, advice, info, aything is highly appreciated.
Thanks.
peace.

...- and it remained in mprime for 20hrs til i showed up this morning--- i guess this is a PSU failure and not a mobo one... (or not?)... what should i be looking for in the PSUs? I noticed (the one that failed) it was hot as hell, not only the MOSFET area but the whole unit was steaming hot.... this particular model has a known issues with the glue becoming conductive and making the MOSFET go Boom! as wel as the PWM IC, and wel whatever crosses i guess... but, back to the point, is it possible that the mobo is asking too much to the PSU or something like that? cause even not using mprime itd shutdown, but take longer... should i just go ahead and replace the power MOSFET and see if it works? -that particular transistor is kinda hard to get for me-
when i didnt know what to do i thought they had something to do with the whole overheating scenerio, but thanks again.
