Hello community,
On a system with ASRock Conroe1333-eSATA2 board i'm having the following issue:
The original video card (MSI Nvidia 8400) broke an after replacing it with a brand new ASUS RADEON 5450 i get eight beeps from Bios and black screen.
I tested also an identical MSI Nvidia 8400 which worked fine.Another card (Gainward 9800) had the same issue while a fourth card with Nvidia 315 chip worked fine.
I updated the board's bios from 1.00 to 1.50.Nothing changed.

Any suggestions welcome.
