Hello everybody, I have recently joined this site. I need some advise regarding my pc issue. Yesterday I powered on my system and it did 'nt boot up. there was no display nor any beep sound. Only the cpu fan is running and the monitor power just blinks on and off. Is it a smps, ram cpu,or motherboard problem what needs to be done. Could any oneplease advise on this. I connected the smps to a different system and it works fine I changed the ram still the problem persist. I connected a worlking harddisk to the system still no go I connected the pc directly to the mains instead of juntion boxs till no go. I have almost tested everything which i saw in the post/replies still i could n't figure it out..... Could any one please advise on this.
