PCI-E version is not your problem. All PCI-E slots are compatible with older versions.

Well first of it would probably help to know what your motherboard is. Like the model number.

The PCI-E will run at 1.0 coz your motherboard does not support 1.1, 2.0 or 3.0 versions so the card runs at the spec of your motherboard, hence they say the cards are backward compatible.

There are ways to downgrade/roll back to previous BIOS check website for your motherboard
info and ways to roll back, mostly eg Intel Motherboards use recovery method, i don't know about yours, so check manufacturer website.

If it happens in a web browser, disable hardware acceleration in that browser. Update the drivers to the latest might help as well.
And just in case, check in the BIOS whether the PCI-E bus frequency is at 100 MHz.

That would only reduce the lanes, not change the version.
