I have another PC where I checked the different parts. I just removed the cmos battery for a min and tried to boot up again, now all the fans are running on the case as well. However, there is nothing happening on the screen and mouse/keyboard. My USB external hd seems to be powered tho

Have you tried running the system without the video card?
