    Windows 8 flickering at startup and shutdown - ati 5470


    Hello everybody! I need an advice.
    Recently I updated my hp dv6 3122sl to win8. Now, obviously the drivers provided by microsoft didn't work, so I installed the softpaq by hp in this order
    1. sp52351 for intel hd graphics (1st gen)
    2. sp50640 for my ati radeon 5470 (it's important to set compatibility with windows 7 for this one)
    and now the switching is working fine.
    However there's a big big problem. The screen flickers 3-4 times at startup and shutdown if I enable fastboot from the control panel, and it's so annoying that I disabled it, sadly.
    I tried to update drivers, using custom drivers by leshcat and later official drivers by ati (13.1 for example, which I installed over the hp ones), and the they -more or less- worked, because I could use the fastboot smoothly... but my pc had several thermal shutdowns since I installed other drivers!
    So I switched back to the old sp52351 and sp50640.

    There it is my question: Does anyone of you (maybe with intel+ati 5470) have flickers at startup and shutdowns?
    If yes, is there a solution or any way to update drivers without make my laptop blow up?
