Vista 64 doesn't detect my monitor

Asus Maximus Formula
Dual ATI HD 4670's
Driver Package 8.64-090714a1-085216C-ATI
Catalyst Version 09.8
LG W2453 HDMI monitor
Viewsonic VX2235wm monitor
current avaiable drivers for monitors exept....

Problem.. I've been tring to figure this out for over a month.
I was playing COD4 and running both monitors sucessfully for a while untill i went from a solid 150fps to 15 fps overnight.

I first thought was i fried my gpu's checked heat range and load so i swapped out with another pair of HD4670's new but different from the other pair (1 set has 2 DVI ports and 1 Svidieo and the other has 1 DVI 1 analog and 1 HDMI)

No change in fps range in game, so i double checked the drivers, and found a new driver just released that same week. I installed the new drivers and still no luck. i swept the comp for virisus's and the like, found a few in sum music files or they said they did afterwards no change in gpu preformance. refomatted and reinstalled vista32 at that time. It seemed to work, for a week or less, so after my first go i decided to reformat again and this time installed vista64. At this time i still get poor fps and cannot play but i also cant get my comp to detect my second monitor. I'm at ends with it i cant figure it out fixing both problems would be nice but i really need both monitors to work.

yes i have tried enableing crossfire
yes i have tried disabling crossfire
all current drivers and no loose cables
yes monitors work confirmed on another system
and yes i've tried using other ports and have isolated gpu's

any help is welcome

ohh yeah... the viewsonic drivers wont complete because vista doesn't see the monitor and wont let me install the drivers

 

Vista 64 needs signed drivers so that's probably it. When you boot, tap F8 to get the boot menu and choose disable driver signing, near the bottom. Hope that works getting drivers in.

 

thanks i'll try that

 

Well I tried it and the Os still doesnt dected it i also got a signed driver package from oem and still cant install for the os doent see the monitor
if i new how to get to the upnp menu id look at it and see if ther was a problem but im not sure how to access it

any other thoughts?
