Bios is laggy and I can't access bios settings but Windows loads, however if I use a backup card (in this instance a geforce 210 ddr3 1gb) everything works fine and I can access the bios settings with no problems.

I was able install the driver for Palit gtx 960 in windows.

I tried to flash the bios off a usb but it wouldn't allow me as the qflash is out of date, apparently it can be updated by creating a bootable dos usb but I don't know how to do that so thought it best to ask for another opinion before learning how to do that.

I don't mind running both cards in my system if it is a work around,I haven't tried this yet.

Can anyone speculate if this is a software or hardware issue? Your guess will be probably be better than mine.

Thankyou, any help would be much appreciated.

Update:

Bios successfully updated to last stable update (F7), I can now access bios settings.

Hopefully I can get things stable now.
