"No display" issue on Asus P5K + GTX 960 also Asus P5K + GT 220

[ArgoP]

Hello guys,

This is my current setup :

CPU : core 2 quad q9450 2.66 Ghz (stock)
Mobo : Asus P5K (https://www.asus.com/Motherboards/P5K/)
GPU : Zotac GTX 960 AMP / GT 220 (no idea what is the manufacture)

I found this "No display" issue during booting process when using these hardware pieces.
I'm suspecting it's due to old bios version, but i cant access the bios menu  due to no display issue.
Any advice? Should i try to purchase older gpu just to troubleshoot this issue?

note :
- The cpu still run perfectly on other lga 775 board like asrock g31m-s
- The gpus also run perfectly on other lga 775 board like asrock g31m-s
- My PSU is Seasonic M12II-620 evo, pretty sure the PSU has enough power for this setup.
