Its been 2 days now am having this problem; my pc power on, the fans and dvd drive are working but there is nothing on the monitor and the red blinking light is not working. i have already swap memory stick and tried with only 1 stick but same result. i then reset the cmos battery but still the same. I doubt the harddisk or the psu.
Any help will be much appreciated
---------------------------------------------------------------
i've already tried with another monitor and no display on monitor and not even the bios.
Also the psu fan is not spining and have to give it a push manually so that it spins.
i've tried booting without memory stick and the motherboard did a continuous beep sound but still nothing.
---------------------------------------------------------------
i've just unplugged the powersupply and replugged it and magically it startup normally...for now
 
Did you tried another monitor ?

Its not the HDD, cause you can still see the splash screen or BIOS menu with a faulty/bad HDD.

It could be RAM, I know you tried but still I have my doubt.

Or it could be MB or PSU, remove all RAM sticks, start the PC, do you hear any beep sound ? if so the MB is ok, if not the MB is culprit.

And look for the PSU fan if its spinning or not, if the fan is spinning then the PSU is probably ok.
