Hello there,
Could you please send us a picture of SN code at the bottom of machine and a picture of purchase invoice?
We need two lines of SN to determine the model number of the machine.
Could you please take a picture of the BIOS main screen of your machine for us to see?
Here is the tutorial of how to check the BIOS version: https://mega.nz/#F!yuISGa4I!s1bQQajKwnsEdzjqq4nopQ .
Then we will see if your BIOS need to update.
Here is a solution: Go to device manager, right click the PCI—update driver—choose the driver from the PC—system device —standard device—APCI controller–click OK
Have a nice day!
