I have lga 775 mobo. I've reformat my hdd and remove the thermal paste of my processor and never put any tp on it after removing. When I start my pc, fans are spinning there is a light on my mobo but there is no display in the monitor. The fans are spinning fast and creates noise. I've already clear the CMOS and replace the battery and nothing happens. I remove the plug of hdd and remove the ram then I start my pc still nothing happens. No beep at all. Lastly I removed the cpu,hdd and ram. Still no beeps no display. What is the problem? Sorry for my english
