    UPDATE: Black screen on boot after windows logo CCC crash


    Hi everyone, I know it's not a blue screen, and I'm sorry if it's not in the good section. But I really need some help and ideas ^^ I posted this topic on AMD forum

    My computer (HD 6870 ; I5 2500k ; windows 7) is having some annoying trouble: when I boot, I get a blackscreen (but with some light switching (backlight I guess ?)) after the windows logo. I have my mouse cursor and I can BLIND type my password, then I hear the sound of windows starting. But I still have a blackscreen.


    I don't know if their was any driver update, I was on holidays, my friend using my computer and he didn't notice any changes, he doesn't know if their was any auto update (he didn't do any manual update).


    Anyway, I uninstalled AMD driver, got my graphic card in vga mode and it boots fine.

    I did many "clean" uninstalls for AMD driver (by software menu in windows, with the clean uninstall amd software, with DDU,both in safe and normal mode)

    Nothing changes, still get a black screen with mouse cursor.


    I tried installing other driver version, i got a whql one for 2014 (13.2 I think), same problem. I tried with many drivers, same problem all the time.

    I tried installign drivers manually (by device manager) and with amd setup. I tried custom installs and full installs.

    My windows was up to date.

    I tried sfc /scannow, no errors.


    In the end, I tried a clean WINDOWS install. So I formated my ssd and re installed windows and ..... Still the black screen when I install the newest AMD driver (15.7).


    I read somewhere it could be a problem with ahci, but in sys32 files, i only see amdsata.sys and amdxata.sys ; i don't see otherssata drivers (like amd_sata/xata.sys) so I didn't try to delete them (like it was advised in some post I read).

    Because I have ssd, i can't go in IDE mode (i tried anyway, it showed the "no operating system" message).

    I think it's a leftover of AMD driver that I can't manage to delete or even find.
    Any ideas guys ? I googled and tried for more than 7hours, out of ideas now.

    Hi guys again, some update:
    I can manage to control my computer with some remote desktop app (teamviewer).
    It means: i ahve black screen with mouse and etc, and if I use teamviewer I can see my screen with the remote device (my iphone in this case).
    If i check the screen spec, it's on 1080p resolution (my native screen res) and it says the AMD driver is working well.

    The problem comes when I try to install CCC, it just crashes (don't know if it's BSOD or not, because the remote connection just stops and I have a black screen on, remember ? ^^). Using "WhoCrashed" doesn't give any info (no dump files)
    Whenever CCC tries to launch (the install is ok and then he tries to launch) it makes the computer crash.

    I think there is come kind of setting I have to change that is in CCC but I can't access it because it crashes...
    I already re installed Windows and i tried windows+P.
