I have problem with my motherboard and graphics card.
My PC specs:
Motherboard: Asus M4A785D-M PRO
CPU: AMD Athlon 64 X2 2.6GHz
Mem: Kingston DDR2 HyperX 2x2GB Dual-Chanel
GPU OLD: HIS X 1550 Hyper Memory 128MB 64-Bit DDR2
GPU NEW: Gainward GeForce GTX 460 GLH 1024MB 256-bit GDDR5
Sys disc: Western Digital 160 GB SATA
Power Supply (3 days old): Cooler Master RS-600-ACAB-L3 600Watts
Operating sys.: Win 7 64-bit
Monitor: LCD Asus 720p 19" (5 years old)
PC run perfect with my old graphics card.
But when i change it to the new graphics -monitor will not start.
Monitor is still in stand-by mode (orange led)
I already tried :
1.I bought new power supply 600W (old was 460W).
2.Graphics is OK - tested in another PC (i dont know details about that pc).
3.CLRTC procedure to Clear the CMOS done
4.Bios i set to GFX0-GPP-IGFX-PCI :GFXO = Primary video controller on a PCI-e x16 slot
5.Yes i check all connectors.
6. Latest Bios used 1001.
The fan of GTX 460 start normally.
Beeping after start is ok .Same like with ok graphics X1550.
Internal graphics HD4200 works fine also.
I think the problem is in the motherboard / BIOS / PCIe compatibility. ?
Got any idea ?
