Salve sono Knulp. 

Non vedevo l'ora di confrontarmi con qualcuno su questo problema.
Ho aquistato una abit radeon 9550v 128m con chipset RV350 che mi da lo stesso problema. Quando gioco dopo alcuni minuti il sistema cade ed appare la "videata blu"; a volte completamente blu, a volte con la scritta DRIVER_IRQL_NOT_LESS_OR_EQUAL.
La configurazione della mia macchina è questa:

Bene ho provato di tutto ma niente da fare, con la maggiorparte dei giochi succede la stessa cosa.
Adesso ho cofigurato il tutto con driver e bios aggiornati, sistema operativo installato dall'inizio, ho provato Rivatuner per migliorare la scheda e vediamo.
