Dual monitor issues

[GLR]

I have an unusual problem I hope someone may be able to help me with!? I have 2 AOC monitors 1920x1080 - I have just installed an OCZ vertex 2 SSD - taken from another PC and I am unable to set up the monitors - one is okay and the other keeps reverting to the size of the smaller monitor on the old PC - and the icons keep moving to the right -- further every time I restart! I am unable to change the home monitor as well.
Asus P6X58D-E - i7 930 - Sapphire HD 5870 PCI-E -- DDR3 - OCZ SSD - WD Caviar Black 1TB - WEI 7.3

The PC I changed the SSD from is a Gigabyte GA-X58A-UD3R - similar specs.
Both Pc's Catalyst C.C. 11.4 - so everything has been installed - reinstalled - swapped graphic cards -- all to no avail???

Any suggestions really appreciated,

I'd boot into safe mode and remove the video card driver then run a driver cleaning program, then boot into normal mode and reinstall the driver you want.
Guru3d.com will have the cleaning tool to use...

Guru3d.com no longer has the download.

Try here for the same thing.

Thank you for the quick response -- I have followed through on this advice -- sadly the problem remains - left monitor reverts to 1440x900 - icons move to the centre of right monitor??
I have spent a lot of time on this and maybe need a clean install of OS -- how can I format the SSD HDD and reinstall windows 7 Ulltimate 64bit -- I have tried this also and can't find a way??

resolved

I have resolved the issue by formatting the SSD and reinstalling windows -- everything is working better than original -- in fact my WEI has gone up to 7.5!

Thank you for the suggestions. This really is a great and helpful site!

Thank you all.
