    I have Acer Aspire 5741G- i5,Radeon HD 5470,Win7 x64
    Display driver sometimes simply stops working during videoplayback in mediaplayers or streaming videos on youtube,everything stops working,black screen comes up and then starts driver video recovery. Notebook is new and I have installed the latest driver,even tryed removing it completely and installing it again but nothing seems to be working:-(

    Did it happen before you've updated drivers too?
    What was the driver you updated to?
    Have you checked if rolling back to Acer-provided driver solves the problem?

    Does it happen in games too?
    Use GPU-Z (sensors tab) to see if those media players use DXVA meaning if video decoding is hardware accelerated by GPU.
    What is your BIOS version?

    Unfortunately I still didn't get the chance to try playing the games.
    I don't have laptop with me at the moment so as soon as I get home I'll try the GPU-Z and tell you the BIOS version. Thanks.

    BIOS v.1.02.
    I tryed GPU-Z sensors and it seems that during the playback on youtube and before the crash Core and Memory Clock are raising from 300 Mhz to 500 and 799 Mhz.

    I don't know if that's normal.
    Tryed one game yesterday for 15 min and everything was fine.

    Yes it's normal- it's GPU accelerated playback.
    Update the drivers:

    Mobile Catalyst 10.10 (direct links)

    Win 7 32bit and Win 7 64bit

    and BIOS:

    the most recent one is 1.15- changes are mostly meaningless but BIOS 1.14 is labeled "Improves system stability". Go straight to 1.15 though- it contains all previous changes in it. ( link)
