HPET and ACPI x64-based PC resource conflict

Hi,

I've just noticed the above error but not sure how to solve it.
I've only just noticed it but need to be enable this in BIOS, but as there is a resource conflict, the option isn't there.
Would appreciate any advice on this.

 

Describe what OS, where do you see event, make a screenshot...

 

Ok too much info and not enough ,might need a bit more info .you want to enable hpet in bios .that should be there . acpi is auto detected if enabled in registry (regedit)

 

I re-formatted and re-installed Windows due to a number of other issues I had.
This seems to have solved it as there is no longer a resource conflict, but I cannot see the option still in the bios.
On another question, if I install a secondary graphics card in the PCI-E 3.0 slot 2 not in SLI mode but for Physx, will both slots still kick down to 8x?

 

Beats me ! On inexpensive motherboard you rarely see 16 x on both slot. Check manufacturer)
