Hi I cleaned my thermal paste on my heatsink and cpu I took the cpu out because I wanted to try it on my other mobo which is exactly the same. When I boot the pc up there's no display whatsoever but the GPU was so loud this happened when I put it back to my original setup. Also the CPU_LED is always on but everything are running such as the fans.

Setup:
p7p55d-e pro
core i5 760
4GB G.Skill RAM
700watt OCZ modular
5870 ati GPU.

*CPU is properly installed and the heatsink
*I didn't remove the mobo
*I reseating the RAMS, tried every slots.
*Double checked every cables everything seems connected properly
*Cleared my CMOS, removed the battery
*Mobo speaker is connected too.

but there's still no post and the CPU_LED is always lit on red, the gpu is loud when i turn on the pc.

Thanks.
