Windows taking an age to boot after adding 2nd GPU

[StonedPenguin]

As per title really, Added 2nd 670 last week and strait away Windows 7 (x64) takes a lot lot longer to cold-boot.
W7 splash screen stays for a good 30 seconds up from 1-2 seconds using the 1 GPU.

I've tried reinstalling drivers (314.07) to no avail. Any idea's?

Cheers

Just to add, When its sat at the Windows splash screen, The SSD that the OS is on flashes constantly loading, No idea what its doing

Yeah its been fine, Not had any issues in any games. I'll give that a go now mate cheers.

With just card #2 (new one) it boots up like it did before with just card #1 installed, All is well.

Then I add card #1 back and it takes long again.

I've not updated this BIOS in this mobo at all, When I first got it I read a lot of horror stories about updating the p8p67/pro's (B3.1) BIOS and it messing things up so I avoided doing it as everything was fine.
I'll have a look round for a new BIOS and cross my fingers

Cheers lads

Edit: BIOS Version 3602, 4. Fixed Nvidia GTX 680 hang when runing with UEFI driver. Look's promising.

Cheers JG, EZ flash2 wont let me update to 3602, It says integrity check failed. I'm on 3207 which is the most recent before 3602 on the asus site.

Tried from asus and same again, Got it from a different source as well and image integrity check failed again.

Tried the 3.0 and it worked, I always thought my board was 3.1 lol

Anyway, It solved the issue and Windows loads as it should now.

Cheers guys!
