New GPU now PC won't boot.

[panda_uk]

Hello
I've just installed a new Asus 6950. Now when I boot up my PC no longer see's my SSD with WIN7 installed on it. Also I can't open my cd-rom drive wen it says DISK BOOT FAILURE, INSERT SYSTEM DISK.

I put in my old GPU and I still get the same problem.

Not sure what to do, any help would be much appreciated.

Loose wire somewhere maybe? Try removing a stick of RAM and booting. Sometimes works for me when mine doesn't want to boot.

Have you been into bios to check it's trying to boot from the right disk? Do your SSD and DVD drives appear in bios?

Obvious thing to check, but did you dislodge some SATA cables when you installed the new card?

Right checked it again and two power cables had become ever so slightly dislodged. Cheers for the help.

Reset BIOS maybe? Seems like its failing to see any SATA devices...
