Graphic card constant black screen HD 7970

[Radder]

Hi, now I would describe my problem after pulling my hairs out. I've accidentally chose the wrong preset that I've settled up in the CCC and it started to crash whenever I've started up my computer. It tried to load up as there is the loading icon from the mouse pointer. I've tried driver reinstalling and sweeping but to no avail, resetting windows 8 and fresh install again and the problem still persists I am at my wits end now. Does anyone encounter this problem before? Is it hardware issue or software?

do you have another system to test the card in? Or another gpu or integrated gpu to test on that system?

Changing to igpu boots up into windows with no black screen problem, unfortunately i don't have any other system to test the graphics card on. I am still trying to figure out the source of the problem. Tried to change the presets after i've re-installed the driver and switching it to the GC and the problem persists.

Hi Radder,

It seems like u have the same problem as I do. (not solved either) U have switchable graphics as well right?

(http://www.tomshardware.co.uk/forum/396077-33-acer-7750g-radeon-7670m-problem).

Have u tried the following:

- boot-up and enter bios
- enable integrated GPU only
(as i understood that way ur comp boots as wel does it?)
- then reboot ur comp and enter bios again (not turn off and then switch on power, but the soft reboot button in windows 8)
- enable switchable graphics
- then exit bios and let comp boot

That way my computer DOES load windows with both cards enable. From there u may be able to install newer drivers or any. However, I have a feeling our puters have a hardware conlict or something. (cards are installed in same I/O address or something like that.)

Succes, and I'll keep an eye on this post as well to see if u'' manage to figure it out.

regards.
