Hi. I installed an used Asus P5k motherboard in my old pc case, which I bought (as 100% testing ok) from ebay. I installed cpu (core 2 Duo E6400), psu (all psu connections), ram ddr2 667Mhz 2 modules and front panel connectios (M/B SW and reset SW). Also I installed nVidia GeForce 210 Rev1.0 1GB DDR3 PCI-E VGA . If I press the M/B SW from case front panel, the fan of cpu and VGA are spinning. But I have not any signal from bios to my lcd screen. An orange led on motherboard is lighting always. But when I press the M/B SW many seconds to close the fans, the fans do not stop spinning. I tried to clear the CMOS RTC RAM by moving the jumper, but nothing. Do you have any idea? Thank you in advance!
