Dobrý den,

mám problém se zapnutím notebooku (Acer Aspire TimelineX 4820TG s Windows 7). Na obrazovce spouštění systému Windows notebook nejdříve zamrzal, poté se začal stále dokola restartovat. Když se mi ho náhodou podařilo zapnout, našla jsem ve složce Windows/Minidump soubor dmp s následujícím obsahem:

Z režimu spánku se notebook probouzí bez potíží. Dokážete mi poradit, co s tím?

Velice děkuji.
