My PC was running fine till yesterday. But when i wke up today and tried to boot it,nothing happenend.as if there is no power at all.none of the fans moved nor any led came to life,nothing at all.then i opened up the cpu box.checked the connections,ram etc. But still nothing moved.it seemed to me that problem is with power suply.but then i noticed something peculier.when i oressed the power button,my motherboard fan moved a bit..just a bit..not even one rotation..probably only 2 degrees.for further diagnoses,i tried a dew more things.second observable things happened when i removed both of my RAMs.when i pressed power button without ram,the cpu fan did two-three rotation..complete rotation this time.third noticable thing happened when i disconnected the power cable of hrd disk.all the fans and leds came to life..cpu sounded as it generally does..there was power in dvd writer.i thought i could boot linux from my cd..but sadly it didnt boot.screen showed-"A bootable devicd has not been detected.please refer to the product guide at http:/support.intel.com/support/motherboards/desktop"...and yes..when i reconnect the hard drive..the situation becomes as it was...like no power..sort of dead pc.
And yes..i wud like to inform..its i3 DH61HO classic series..i hav four gb ram..and not any graphic card installed other than the one which comes inbuilt.and hrd disk is of seagate.please help me.
