Vakar atnaujinau BIOS draiverius, tik kiek keistas pasirode ju 
instaliavimas - tik paleidau, ismete dos langa ir greitai ji uzdare... ar 
taip gali buti? Issirinkau pagal :

The GV-NX85T256HP is equipped with 3D-Active Fan a NEW Gigabyte Fan 
technology. 3D-Active Fan will not operate under non-3D 
instruction-executing environment, this feature allows the system to be more 
energy-efficient and prolongs fan life. When the system is instructed with 
3D-operations the 3D-Active Fan will operate automatically to enhance VGA 
card performance. HOWEVER if users wishes to keep the fan working under 
anytime , PLEASE DOWNLOAD THE FOLLOWING BIOS: version--F4A / version--F20A

Parsipuciau is gigabyte.lt video draiverius 175.19 (GIGABYTE NX85T256HP 
8500GT /256MB), suinstalinau - lig siol dar nesmigo ir GTAIV normaliai eina. 
Taip pat pastebejau kad kai paleidau GTAIV, pasileisdavo video ausintuvas, o 
isjungus geima -nesisuka. Gal pakanka 2D darbui pasyviu radiatoriu...? Bet t 
oC islikdavo apie 80laipsniu.
