سلام
فکر کنم دو راه وجود داشته باشه (در صورت خراب نشدن کارت , چون بعضی مواقع تعویض بایوس باعث سوختگی رم میشه )
اولین راه استفاده از دو کارت گرافیک هست که حسین جان استفاده کردن
دومین راه هم در صورتی هست که شما فقط تصویر نداشته باشید و در واقع سیستم بوت شده باشه و مثل این باشه که از بخوایید با چشم بسته کار کنید .
