HELP!!!

[lintonam]

Trying to upgrade existing system to an SLI setup

Have Gigabyte GA-M57SLI-s4 Motherboard
just upgraded from a different one

Now have 2 GeForce 8800 GT Graphics Cards.

Everything displays fine on start up, however there is a message stating that windows needs to be repaired ( VISTA).

When i run the install disc all that displays on the monitor is the top left hand corner of the screen.

I am unable to do anything to repair the windows installation.

If you have any ideas on how to either make the screen visible fully or  be able to repair windows otherwise please let me know.

It sounds like you need to do a complete reinstall of the operating system.
