I have removed amd / ati drivers and disabled my on-board card, removed the 6990, added the 880 but now my laptop won't POST or go into BIOS it just hangs at the alien logo...

Have tried removing the 880, power back up and she will go into windows and BIOS. Tried changing the BIOS settings in advance from SG to PEG power back up with 880 installed and she is recognised in BIOS but still won't load into windows!

Should I install latest driver for 880 and try again or should drivers always be installed after card install?

Any help would be appreciated
