    Hi guys hoping someone on here can help. I have upgraded my gpu’s from 770m sli to 980m sli. First boot I got the Alienware logo come up but had faint blue lines running vertically across screen, so powered off and opened back up and checked all connections to make sure they was all seated correctly. Assembled back up and fired system up.

    System would turn on as all the lights would come on but had a black screen. So I tried the ram hot swap and was able to boot into windows. Went into device manager and get 2x unknown device with yellow triangle. Restarted and went into bios and it was set to igpu. Changed to PEG and restarted. Still shows unknown devices in device manager.

    So I thought the cards don’t have a vbios so are not being recognised. So I tried to install Prema v2 bios. Ran bat 1 file got c prompt window come up and then do it’s thing and then said unsuccessful, then I tried running bat 2 file which same again c prompt window popped up but this time I got error no display adaptor detected. So I turned system off and disassembled again and made sure cards were seated correctly which they were and then noticed sli connection on 2nd gpu had come off. So reconnected and reassembled.

    Turned on and I still get unknown device in device manager. So tried to run premas bios again and now all I get is c prompt window pop up and disappears in a second. With all the frustration this process had caused me I may have done something wrong. The .rom files show they open with winrar which I know is wrong. Can’t figure out what to set the open with option to. Googled this but there’s not much info on what program is generally used to run .rom files.

    Deleted premas folder from desktop and redownloaded but the .rom files still come up as winrar files.

    I have no clue what to do so hoping someone a little more experienced in this can shed some light.

    install Dell's vbios before Prema is highly recommended you need to run the .bat files as admin, or force flash then yourself via CMD. you also should have kept the graphics drivers installed. Try and installing the graphics card driver so the card then should be at least generic VGA Adapter

    I have no experience with the AW18 but is modding the INF required with the 980m's for this laptop?

    hmmm ok... lets try to force flash premas vbios then... throw everything from premas vbios onto your C Drive like right in the first panel of it where u can see program files and windows etc. then you want to run CMD a an admin and to cd c:/ then try to flash the first card with
    nvflash -i 0 -6 -f 980MPMA1.rom lemme know if this flashes
