I have an XMG Clevo P150HM laptop with an ATI Radeon HD 6970 M graphics card and a Full HD display. When I boot it, the BIOS screen is there, then there is the Windows logo and then the round thing turns, but when there should be the login screen, the screen goes dark and stays that way.
Additional research revealed something fun: reinstalling Windows 10 runs without any problems. But when Windows installs updates and drivers, as soon as the ATI driver is installed, the screen goes dark and stays that way. I tried twice, the second time I installed drivers downloaded from the ATI website instead of the drivers through the Windows update mechanism. At the time the ATI drivers are installed, the problem occurs. This is a fairly new development, I have been using this laptop for quite some time and it worked fine.
Then I wanted to install Linux, but I didn't get that far: after the BIOS and the grub screen, the screen goes dark and stays that way. Apparently, after the grub screen, the boot process changes to another resolution, probably the native screen resolution, which seems to trigger the problem. The Linux distributions I've tried are Ubuntu 18.04 and CentOS 8.1, booted from a USB stick.
Finally, I connected the laptop through HDMI to my TV. During the Windows boot process there was a text & # 39; No signal & # 39; on the TV But at the time when the laptop screen went dark, there was a reaction on the TV: the text & # 39; No signal & # 39; disappeared and there was an input indicator & # 39; HDMI 1920×1080 & # 39 ;. Other than that, the TV screen remained dark as well. Once I disconnected the HDMI cable from the laptop, the text reappeared & # 39; No signal & # 39 ;.
I guess there is something physically broken with the graphics card. My question is, what exactly could that be? Has anyone experienced something similar and researched more? Is there any reasonable chance that I can fix this?
