Hi all!

Today i installed a HD 4870 (second-hand, but i'm pretty sure the GPU works fine).
Problem is, when i boot up my pc, the screen takes more than expected to "wake up" from the "stanby mode", and when it wake up, i can only see a really messed up light-blue screen that says somethink like:

"The pc will be restarted...checking the pc for ptoblem tot% completed... VIDEO_TDR_FAILURE atikmpeg.sys"

And all the screen is messed up with some little grey bars and lines all around.

I'm pretty sure the PSU is giving enough power for the GPU.

If instead i boot up with the screen plugged in the IGP, the pc starts up normally, and it recognize the HD4870. I've installed the latest CCC and the latest driver for the GPU.


PC specs:

system win 8.1
mobo p5k
4 bg ram
PSU rasurbo DLP55.1 550w (with 19A and 18A +12v lines)
processor Intel Core2 Quad cpu Q6600 2.4GHz

Thank you for your time and your help
Mario

PS: i've googled the problem for hours, in this and other forums, without finding a useful solution.
 
The problem may be the driver model. That card only supports WDDM 1.1 Win 8 is WDDM 1.2. it is possible that there is no solution to the problem because of this. You stated that the Video driver is the newest version. Ensure that you are using the newest chipset and ACPI drivers. beyond that I would say disable sleep and use hibernate or just shut off the computer.
 
It's a known issue:

Some people said they got a newer card. Some said they reinstalled Windows 8 and it worked, but others said it did NOT. Not sure what's going on there.

My advice is THIS if you don't find an easy solution:

1) Buy an inexpensive HD6450 or similar if you don't game. or

2) If you do light gaming, buy the Asus GTX750Ti for about $155 USD.
