Vista - Vista + dual monitors = crapfest...

I don't know what is going on. I updated to Windows Vista from XP about a week ago. Installed all my drivers and everything worked great for three or four days. But, all the sudden and for no reason at all I woke up one morning and only had one monitor able to recieve a signal from my computer. I checked all my connections, checked all my equipment to make sure nothing was broke, updated all my drivers.

Now it's just funny. When I restart my computer sometimes my computer randomly changes which monitor works. Sometimes both work fine, sometimes both work but they're switched (it thinks the second monitor is the primary and vice versa). Sometimes both will work fine until I do something, for example if I'm browsing the internet and I click on a random link a monitor will just lose signal. Sometimes they both lose signals.

What is going on? I never had any such problems on XP. Then this problem begins in the middle of the night one night?

Oh and specs...

Vista 32 Home Basic
Lan Party UT NF4 Ultra-D motherboard
Nvidia GeForce 7900GS videocard

With an nvidia chipset I would not use the microsoft drivers, I would rather get the latest forceware from NVIDIA. Then you can use that control panel to properly configure you dual monitor display.

what 2 cards are you using?

I'm just using the one video card that I mentioned at the bottom of the original post.

I have the latest forceware for nVidia installed and that's what I use to configure everything. Even it can't find the monitors sometimes.

I need to know how much RAM you have and what kind of monitors and connector type you have.

This monitor screw up happening as the computer is turned on before Windows even loads (still on the bios/boot screen)? If so then it is a hardware problem and not a Vista problem.

I've never goten this problem for me, i run Vista Ultimate 32bit. but though soon, i plan on downgrading back to XP since this is possibly a graphic card problem, vista + Nvidia drivers dont work so good together

check this website and tell me if these are any of the errors you are getting

www.nvlddmkm.com if so, then i'd get a new graphic card or simply just downgrade back to XP

Are you using the same type of cable for both monitors?
Check the seating of the connections, if one is loose then you will get this type of behaviour.
Are the monitors of the same resolution/refresh rate?

i am using 2 x VGA cables both using a VDI plug
