MSI mobos and ATI graphics card incompability!

Question

I don´t know how well known this problem is but I´ve seen it on this forum and when googling the internet you can find it!
The issue is that I can´t get my HD5450(Sapphire) to work on my MS-7267 (945GCM5-F V2) mobo! The screen stays blank but the PC boots up and loads Windows.
The HD5450 works fine on other mobos with different PSU´s ranging from 350 - 600 watts, but when trying different PSU´s on the 945GCM5-F V2 it doesn´t seem to help. I´ve also tried different bios settings, I´ve cleared CMOS, I´ve tried both dvi and vga outputs, I´ve disconnected as much as possible from the mobo except from the graphics card and the PSU, but nothing seems to help!
Any ideas , someone?
Tekrar!

Thanks for all replies!
I had this question on the AMD forum (AMD Game » AMD Technology » Radeon Graphics » MSI mobos and ATI graphics card incompability!) and here are some of the replies:
"Well, its a known issue that older chipsets, like even AMD 580X chipset, doesn't work with 5k/6k series cards without a bios update from the manufacturer of the board.
If its not working / posting / no video ect... You need to bug MSI to update the bios on the board to support the newer 5k/6k video cards. It may or may not happen. Several manufacturers have like Asus, and Gigabyte."
"Same problem. 5450, MSI MS-7267 (945GCM5-F V2). Done the same plus updated msi mainboard bios using msi live update 5 etc. Waiting for reply from makers of graphics card and mainboard.
I should add from what I've read in other threads and forums it seems to be an old mainboard problem not just related to the MSI 945GCM5-F V2. Some other manufacturers of mainboards have sent customers bios upgrades to get their cards working.
As for your pci express version question. Well these problems seem to emerge when people have plugged these pci express version 2.1 cards into their pci express 1st generation slots. What exactly the problem is here? Leave that for manufacturers/experts to answer."
"Tek , its hit or miss on the board + chipset combination on if the card will work or not. Sometimes they will work in old boards, Sometimes they will not w/o manufacturerer support.
Its completely random from what I've seen on the forums at the times they were released , when people with old boards were asking why it wasn't working. And what they did to solve it. Most all of them emailed the manufacturer. Some of those said manufactureres provided beta bios back to the customers, some said your out of luck."
Its true, this MSI MS-7267 (945GCM5-F V2) isn´t a new mobo, but when I get the 5450 to work without problem with an even older fujitsu mobo (last bios update long time ago) and a 350 watts PSU I think something´s wrong.
So, a bios upgrade would probably fix it if the manufacturer (in this case MSI) just wanted to!
