New boot issues

[TSGrayson]

I am having some odd new issues with my computer. I run a dual boot XP and Vista system and sometimes when it loads...I receive no video output and there is no motherboard beep for no Vista....I never see the mobo screen and it will take me two or three times before it will boot right....any ideas?

I am running a QX6700, 2 gigs of ram, Asus Striker Extreme and 2 GTX in SLI.

Also, now it will sometimes stop having video output

You need to clarify whats going on here.

Does the PC POST?
Is it able to POST, but you're having problems loading Windows?
Are your problems with just Vista or XP?
Are both having problems loading?

Are you OC'd?
Ever run Memtest or Orthos to test for stability of your system?

What PSU are you using?

Answer some of these questions and maybe we can get a better handle on whats going here.

The PC does post but I can not really tell because of the video output issue. No beeps and nothing displayed.

I have a slight OC to 3.2 gHZ and am watercooled...all temps were fine.

I am using the BFG 1000W PSU.
