Display driver amdkmdap stopped responding and has successfully recovered
So, Recently I was solving graphic card issues. It all ended with buying new GPU and PSU.
I bought sapphire hd 7750, and seasonic ss energy kinght 500w. Had opened thread about it.

It all started few months ago when I was getting msg that display driver had stopped working and successfully recovered. This was coming with few seconds screen fading and then came back to normal. Usually it screwed up any opened game which crashed, and I had to start it again. I didnt pay much attention to it until my screen started fading regularly and wouldnt come back anymore. I had to turn off my PC and start it again. I believe that my old nvidia 9600gs was also overheating, and being pushed beyond the limits, and it died in the end.

So I bought new card as mentioned above, thinking it was old card problem, but no ...
Very soon after buying new card I started getting same thing. Im at the point where it just fades down for few seconds and then recovers and works again.

Now here are my specs:
2.4Ghz quad q6600
4gb ddr2 ram
Vista 64
7750 hd sapphire
things I tried to solve this:
-After mechanical instalation of card, I noticed this card isnt being connected by any 4/6 pin cable from PSU. Dont know if it cant be under powered or something, but I didnt find any small port on it to connect additional cables.
- I installed all drivers from DVD I received with it. Strange thing is it says that my card is 7770 and that drivers are for same card, even though on box it says its 7750. So Im not even sure what card I have. I ordered 7750.
-I tweaked my Vista and cleaned it with tuneup 2012, to higher degree.
-Updated it to latest updates. What I noticed after this, was slightly faster system response. Even its usually not too bad.
- Did some search on internet about this issue and found that its pretty often happening to people. Some solution was mentioned that this is some catalyst problem. and im to set vista appearance to basic, which seemed to work just until the problem occured again about day after ..


I'm fairly clueless already.. Will appreciate every advice. Thanks

Download latest drivers here http://www.sapphiretech.com/presenta...pid=1454&leg=0#

Uninstall catalyst control from your computer through control panel/programs and features (do not restart)
Uninstall current video card driver through device manager (do not restart)

Install new drivers restart if prompted.

Guess there is something wrong. graphic card doesnt appear in device manager anymore, only standard vga adapter, and it has yellow triangle on it with black exclamation mark.

Dont see option for disabling onboard graphic there.
Only to choose primary graphic and there are 3 options:

PCI
PCI x16
PCI x1

Mine is set to PCI. Shouldnt it be set to PCI x16 ?

will post system info in a minute.

I did set it to PCIx16 now, with no visible change yet. About to try reinstalling whole catalyst install manager again.




EDIT : After uninstalling it, it doesnt dissappear from programs and features list.
Its called AMD catalyst install manager.

Sounds like it didn't install. Don't forget to check device manager after you reinstall.

Right. Second installation was fail again. but third has finally succeeded!
I noticed right away during installation process that there was something different going on, unlike the first two. Card is finally installed properly (i hope), and now its only about waiting if issue with display driver has stopped working will be poping again or not. Lets hope It will be fine, and I'll have my PC working again after so long time.
