Hi Banpin90,

Try the following steps on this article. Let me know how it goes.

Hi banpin90,

I will be glad to help you. Request you to answer the below questions:

(1) Are there any beep codes coming from the computer?

(2) Is there any light on the tower? (Just above the Alien head logo on the front side)

Do reply with your findings.

1. I did not hear any beep sound

2. Sometime there is light sometime when the light is not on I pulled the plug out and plug it in again and press on button the light will be on, but the still the only thing happen is loud fan noise and nothing show up on my screen.

I did the power check everything look fine, for the CMOS I cant find the CMOS in the CPU. I am not very good with computer.

I thought you talk about the the Alien head my bad, the light on the tower is not blinking nor turn on.
