Hi
If your PC will not get past the XUM post screen or goes into the bios and stays there, or the screen goes blank just after the post XUM screen appears.
If you see Error Codes in the bottom corner of your screen
Error code 'A0' can mean that the HDD or NVMe has a problem.
One possible fix is to check the Hard Drive HDD, & or the Solid State Drive SSD or NVMe connections.
Turn the PC off and open the glass panel
Locate the SATA cable connector and unplug it gently from the motherboard (see the attached pictures)
Will the PC boot with this cable disconnected ?
If the PC will now boot the issue is with the cable or the HDD itself.
Try the steps one by one to try to isolate the issue
1 Try to move the connection to another SATA socket on the motherboard you should usually have 4 SATA ports & only one is occupied by default on our builds.
To move the port just unplug the cable & plug it into one of the other ports.
2 Try a different SATA Power cable, coming off the Power Supply PSU, to the HDD you should have several spare connectors to try from.
If it still doesn't boot do you have another SATA cable you can try
If you dont have a different cable let us know and we can send you out a replacement SATA cable.
3 If replacing the cable did not work. And if you think you are able to change the HDD yourself, we can send you out a replacement HDD.
Changing the HDD Its just a case of unscrewing the retaining screws on the old drive unplugging thew cables, then reversing the process to put the new drive in.
If the PC will still not boot with the HDD cable disconnected the issue is most likely with the SSD or NVMe.
Once again with the PC turned off, locate the NVMe card and unscrew it. Simply wipe the gold contacts with a clean cloth and blow softly into the socket. Then replace the card and screw it back down.
If the PC will still not boot after replacing the card the NVMe has failed.
We can send you out a replacement NVMe with windows preinstalled if you feel able to fit the card yourself. Its just the same as the procedure above except you are swapping the cards over.
If the PC will now boot up but you are getting a select boot device error let us know and we can send you some slightly different instructions to fix that.
Error code B2 on the XUM screen, may mean that you need to reset the BIOS, see instructions below
