Alienware 17 R1 from 880m to 980m problem

Hello friends,

Short story: my old 880m burnt down so I had to get a new gpu so I chose gtx 980m. Got it from aliexpress.
Right after I've installed it I started getting 8 beeps. So i plugged in to my TV via hdmi cable and then my laptop booted up normally. So then I downloaded the latest GPU drivers (451.48) for 980M. I had to modify nvdmi.inf file, disabled driver signature authentication and installed the drivers without an error. Everything seems to be good with the gpu, I can play games etc. but after every restart I keep getting 8 beeps until I connect my laptop to TV via hdmi cable. Anyway I can fix this?

Alienware 17. A17BIOS
i7-4910MQ

Hardware ID:
PCI\VEN_10DE&DEV_13D7&SUBSYS_05AE1028&REV_A1
PCI\VEN_10DE&DEV_13D7&SUBSYS_05AE1028
PCI\VEN_10DE&DEV_13D7&CC_030000
PCI\VEN_10DE&DEV_13D7&CC_0300

Lines I've changed:
%NVIDIA_DEV.13D7.05AE.1028% = Section043, PCI\VEN_10DE&DEV_13D7&SUBSYS_05AE1028

NVIDIA_DEV.13D7.05AE.1028 = "NVIDIA GeForce GTX 980M"

 

can you post the picture of your vbios i mean gpu z. because drivers has nothing to do with the 8 beeps code

 

Hope that helps

 

can you flash this vbios after backing up your official one if this one doesn't work the problem is with your screen.

 

So I'v flashed the vbios with your given file but no success. But the screen is working fine, I only need to turn on the computer using hdmi cable connected to TV then I can use the laptop without it. I doubt it's the screens problem.

 

Are you on 60hz or 120hz, could be a faulty gpu does the laptop work fine without the gpu

 

Well, either on 60 hz or 120 hz I still get the beeps. I can't really try testing without the gpu since I don't have integrated one. I'll bring the laptop to someone who fixes them, maybe I'll get some answers. Thanks anyway.
