If removing one RAM stick worked, check wid others too.

I would say, check ur SMPS...

I had d same experience one month back, in my case it was concluded dat my MOBO is dead...

i tried the following-
tried all my ram sticks on a friends p.c one at a time they all are working fine on his system.
all fans of smps, graphic card are working.
took out all the connectors and plugged them again.
i cleaned my p.c, blow the dust.
removed cmos battery.put again.no result.
took out graphics card and tried to use the motherboards onboard graphic for display.still nothing.

all the above did not work. only one time my pc started(i think out of luck) but again froze when i played a video.it froze and when i restarted again no display no bios nothing.
