    So my 980M has finally given up on life leaving me without a laptop. My question is, if I don't currently have the money for a replacement 980M, could I look into getting a cheaper 970M instead? I'm just looking for a plug and play replacement, prefer not to have to fiddle around with hardware mods or even BIOS stuff.

    Yes if it's a Clevo 970m then that should plug and play.

    Ok thanks, figured it would since it has basically the same dimensions and layout as a 980M, just wanted to be sure. But after searching around on eBay the 980M is only about $100 or so more expensive so I may just suck it up and stick with that.

    Might be worth checking out the members market too.

    Yep I checked here but didn't come across anything. Found an eBay seller that stocks the 980M that should be compatible with Clevo models for $300. All in all not too bad, just have to wait for shipment from China.

    So just to update, I received the replacement gpu today, however, it doesn't seem to work. Laptop powers on, but there is no display, and after about a minute or so fans go to maximum with flashing power button and shuts down. Same thing that happens when no gpu is installed at all. Any ideas what the issue could be?

    Update: Tried again after removing CMOS battery and it still does the same, only this time it started beeping before turning off.

    Update 2: Put the heatsink back on (left it off the first time around since I was just trying to test if the card actually worked or not, didn't think any overheating situation could occur that quickly), and now it seems to stay powered on and may even be getting to Windows, but I still have no display so of course have no clue what is actually happening. I wonder if this has anything to do with my laptop originally being a g-sync model (according to the seller the replacement card is non g-sync).

    Update 3: Now back to spinning fans and beeping before shutting down, even with heatsink in place. I'm stumped and have no clue what is going on anymore.

    So I was able to seemingly get into Windows and decided to try blind flashing a stock Clevo 980M vBIOS using the instructions from https://www.techinferno.com/index.p...oot-blind-flash-a-non-booting-gpu-in-windows/. However, after Step 8, I get 2 quick beeps. I tried following the same instructions using an old Windows 7 laptop that I have lying around, and I get the same 2 beeps, then an error that says "Unable to setup NVFLASH driver <0x00000002>". I'm assuming the same error is what is occurring when I attempt to blind flash the 980M. Other than that it has been running for about 20 mins with no shutdown, so I think I can get this working if I can just figure out the vBIOS situation.

    Update: Now after Step 9 I'm getting 2 quick beeps. According to the instructions a successful flash should result in just 1 beep. Enabled logging and it appears the flash isn't working due to 'no nvidia display adapters found' error. Maybe because you're supposed to disable or uninstall the driver before attempting to flash a vBIOS, but that would be near impossible to do blind. Very frustrating but I feel there has to be someway to get this working.

    You can manually program the chip with something like a skypro but I would speak to the seller of the card as they advertised it as compatible.

    Wow, that was a big no no right there. :eek::eek::eek:

    But you can manually flash it as meaker said. SPI programmers are fairly cheap and good to keep around for problems like this.

    I prefer blind flashes in dos vs windows. Create a batch file that will update or write a txt file to signify success so you can check it on a working machine to see if the flash took.

    Do you know anybody with an SLI machine? They can check and flash in the secondary slot and see everything that is going on.
