Computer will not Boot Up

[WeaponX2099]

Please help, my computer will not boot up.  At first, the computer had no power what so ever, until I replaced the power supply. It lights up now, but no boot screen. It's not the HD, because I switched it with another and only made the same sounds. There is no beeping, only 2 clicks from the HD. Fans start and other components light up but nothing else. Help!!!

@WeaponX2099,

It is great to have you back and your patience is greatly appreciated.

Are you getting any display on the screen?

Have you followed all the steps suggested in the article?

Meanwhile, I recommend you connect the computer to an external display or to your TV and check if you are getting any display. Also, I recommend you try booting to BIOS by tapping the F10 key on startup and check whether you are able to access BIOS.

 Let me know how it goes.
