Video Card not recognized in PCI-Express x16 - Slot Security

[_SOLER]

I disable PCI Express slot in Computer Setup -- Security -- Slot Security on BIOS.

I doesn't know that my onboard card wasn't working, and now,  machine doesn't start, machine beeps 6 times (video card error).

I can't access the bios.

I try reset CMOS, removing the Green Jumper, removing the battery, press CMOS button for 10 seconds, press power button (to remove remain energy.

But nothing this works.

Someone can help me?

How i can reactivate PCI Express x16 ?

Hi:

If your onboard video adapter doesn't work, and resetting the CMOS doesn't work, you can try putting the PCI express x16 video card you have now into the white PCIe x4 slot (the white video card slot next to the black PCIe x16 slot), and see if you can get into the BIOS to change the PCI x 16 setting.  It might work in the x4 slot.

If that doesn't work either, then you will have to install a PCI video card (one that goes into one of the white PCI slots) and use that to get into the BIOS so you can change the settings to enable the PCIe x16 slot.

So, see if you can find a cheap, used, PCI video card on eBay, and that should allow you to have video again.

You also need to make sure you have removed all connections from the PC when you reset the CMOS (all cables, power cord, mouse, monitor, etc).
