مشکل برای کارت ati 3870

با سلام
من یک کارت 3870 ati گرفتم وقتی روی سیستم نصب می کنم گاهی سیستم بوت نمی شود و در مرحله logo ویندوز که میرسه دیگه جلوتر نمیره و هنگ می کنه !!!
اما وقتی vga رو عوض می کنم به راحتی بوت میشه !

خوب شما جواب خودنونو دادید مشکل از کارت گرافیکتونه.

چون گرافیک در حال بالا اومدن ویندوز گیر میکنه میتونه خیلی راحت از درایور کارت باشه ، ایا شما توی Safe Mode هم همین اشکال را داری ؟ و ایا وقتی ویندوز تازه نصب میشه هم همین مشکل هست ؟ ، آیا شما برق کارت را وصل کردی ؟ گردش هوا دور کارت خوبه ؟ حتی من مواردی را دیدم که هیت سینک توی حملو نقل از روی کارت فاصله گرفته و این باعث اشکال توی کارت شده که البته با یک زور کوچولو درست شده ، در آخر هم ایا پاور خوب هست ؟ و البته چیپ مادر برد ضعیفه ، شده جریان فیل و فنجون !!!
