What you should do in the meantime is roll-back your drivers. In other words restoring them to what they originally were before you upgraded them.
Right-click on 'My Computer', then go to 'Properties'
Click on the 'Hardware' Tab, then click on 'Device Manager'
Click on the '+' next to 'Display Drivers', then double-click your Display Device.
Click on the 'Driver', then click on the 'Roll Back Driver'
This should uninstall the new drivers that caused the stuff-up and restore the original ones. See if this fixes your problem...then try and install those Omega Drivers I told you about..
