Помогите, пожалуйста, разобраться. Комп давно уже начал работать нестабильно – не отследил, после чего, к сожалению. Думал, блок питания, но, вроде, нет. Единственная воспроизводимая ошибка приведена ниже. Возникает в D3D приложениях: 
   Код ошибки: 0*0000008e  
Виновник: nv4disp.dll    
Конфигурация:  БП: FSP MP400-W 
 CPU: P4 3.00 GHz Prescott 
 MB: ASUS P4P800 SE (bios последней версии) 
 RAM: 3 Gb Kingston (2x512, 2x1Gb) 
 Video: GeForce 7600 GS 256 Mb AGP (Gigabyte N76G256D-RH) (bios последней версии) 
 HDD:  Seagate ST3250824AS    
Что я делал:  1.    Померил весь вольтаж при полностью загруженной системе (stress  test). Все идеально. 
 2.    Постоянно мониторю все температурные режимы – все в норме – не более 50-60 град. 
 3.    Вычистил весь комп от пыли 
 
  4.    Просмотрел материнку/видюху на предмет вздутых кондеров – нет таковых. 
 5.    Протестировал RAM двумя разными программами (testmem и memtest 

) – нет ошибок. 
 6.    Протестировал память видюхи двумя разными программами – нет ошибок. 
 7.    Переустанавливал драйвера видюхи – 5 разных версий с предварительной очисткой от старых.
