I am Wrkng in Guwahati as a graphics designer, my office pc wouldn't start and after unplugging and plugging the power cable few time after 1 or 2 hrs it will start up.I think its a branded assembled pc of Raven cost 1.5 lakh...
If I press the power switch it will just blink bt won't start...then i will unplug it & do the same & it won't start....
I am guessing what it problem might be coz i changed the power cable, checked the internal wires, changed the ram sloths. Nothing worked..:-x::-(
PLZ GIVE SOME SUGGESTIONS...

does it happens that when you press the power button , the fans,LEDs star for seconds and then all of it stops
and sometimes nothing happens(not even LED/fans start)

btw check your PSU with some other system

i had exactly the same problem
motherboard turned out to be culprit
and it NEEDS to be changed

Actually, the technician came to know where or what caused the problm.
The PSU have 2 outlets to the Processor...if the 2 were connected 2gethr..the PC won't start..but when it is tested Singly...it starts..
So, they & I both thought that its the PSU that's unable to supply the power....
Bt I also think MBrd is having trouble collecting the power..
& Sorry They took the PSU with them 2 check...

Also had the same problem so i eventually gave up and took it to the shop, turned out i had an extra brass stand off in my motherboard and it was causing it to cut off. worth a look?
