I wouldn't rely on one person saying he doesn't have a problem with a specific BIOS version
unlesshe had the same problem as you with a different version.

I'm not familiar with Biostar but many motherboards share PCIe slots with other devices.
Look for BIOS configuration options that may have the slot disabled in favour of something else.

It could also be CPU related. Some motherboard features may be limited with a Celeron.

The motherboard user manual should have all the details.

One thing you can try is move a card to slot 8 from another slot. That will tell you if the problem
is the slot or something else.
