this has happened to me twice so far. Whenever i update windows 8 and it restarts i proceed to shut down my computer, then the next day i turn it on it starts up with a blue screen saying the shutdown was unexpected and it says this "the "unknown" driver (C:/windows/system32/drivers/atikmdag.sys) appears to have caused a system crash." Now all that i modified on my dell system is i upgraded the stock ati graphics card which was a 75?? to a radeon 7770. And i looked up the system and it is from the first day i started up the system. I think that this old driver that belonged to the old Graphics card is causing it but just want to make sure it is before i remove it. Please help me.
