Seriously, you don't screw around with a VBIOS unless you know what you are doing, and there are very few cases which require the VBIOS to be updated, and in those cases, they are provided directly by the manufacturer for your exact SKU.
I have a problemwith thisvideo card. When playing games orwatching videofails: blackscreen orwhite orblack and whiteverticalstripes.I updated theBIOSof the motherboard, put thelatest version ofCatalyst.
my configuration: Intel Core i5-3570K 3.4 Ghz, ASUS P8Z77-V LX, Hynix DDR3 PC3-12800 4GB *2, Sapphire HD 7850 2GB GDDR5 (11200-07), Chieftec A-80 CTG-600-80P, Win 7 x64
The problem is notin the power supply.600 wattsis enough forthis configuration. Overheatingis not a problem, because thisproblem occurswhen watching movies.
If, however,the fact is thatyou write,that's howto check it.Orcouldsomething elseto do.I updated theBIOSto the latest versionon the motherboard,isCatalyst12.11beta, clear CMOS. Iwould referto the servicecenter, butby January 8is not working.
