I have uninstalled MSI Core rebooted the system and then downloaded and reinstalled MSI Core Center from their website, so far the warning message has not made an appearance.
Thanks Martin, the warning message has come about since I upgraded HWiNFO and I've been running HWiNFO pro in the same system for over a year. MSI Core Center hasn't been updated for a good while but I think i need it to control the motherboard RGB. Is there a simple way to roll back the HWiNFO...
