yesterday,i cant turn on my pc all of a sudden, i thousgt it was the switch of the case, so i removed them and turned it back, nothin happened, so i disassembled my pc, i didnt remove the seidon 120m cooler to the processor, cause its a pian for me, cleaned the rad, the board, the graphics card, even the whole case, it ttok me almost 3 hours, assembled them, then it switched on, but no display..

the fan of the seidon spins fast on start-up, then turned really slow, i can also hear a weird sound from my gpu, turned off my pc and unplugged my memory, got an eraser and cleaned it, plug it back, then voila! i got a display..

i turned off the pc again, removed the cords cause i have to return both the side panels of my 902..

placed it back, and turned on my psu, my pc didnt start, turned off my psu, then my pc starts to power up..

my power supply I/O switch SWITCHED, really switched, did it happen to anyone here?

i didnt disassmbled my psu.. its an FSP raider 750w...

can somebody eexplain this? thank you..
