Product: HP Compaq dc5800
Operating System: Microsoft Windows 10 (64-bit)

Hello, I'm new in this community. Please bear with me. 

I have HP Compaq dc5800 Small Form Factor. Yesterday, when I turned on my computer it has no display and after a few seconds the fans begin to run loudly. It can't be turn off when I'm pressing the power button even for a long time, so I turned it off in AVR. I turned it on again, then boots properly. The problem is that when I turned on my computer today, it goes the same way like what happened yesterday and now I can't fix it. I cleaned it all earlier including its case and internal components. I removed all the RAM but my computer doesn't beep and the power still turns on with no display. What do you think is the problem?
