XFX 750a SLI mobo
AMD Phenom 9500
EVGA 9800 GTX+ (2x SLI mode)
Win XP 32 SP3

I updated the BIOS to V1.3. Since the upgrade, when I switch on the power I get no screen images at all until the windows welcome screen. I still get the POST beeps. I can't go to the BIOS setup because nothing comes up until windows loads. I've tried switching to the mobo video output with not change. I'm really in the dark here. Any help would be appreciated.

Ok, after some troubleshooting I found out that the problem only happens when I have SLI enabled in the BIOS.

The graphic output may be going to the card your monitor is not connected to. Switch your monitor cable to the other outputs. I believe you have a pcie graphics card in your machine but since it is not the primary it will not display until you enter windows. Your boot screen is probably available on your built in graphics connector. When you enable SLI it activates the hybrid SLI and output goes to the built in connector.
