My PC specs: Asus M4A79T AMD Phenom II X4 955 BE G-SKILL 4 GB DDR3 Nvidia GeForce 9600GT 1GB Thermaltake Toughpower 700 W I have a very weird problem with my custom desktop. 3 days back I got BSOD errors/ STOP errors and it read some driver may not be working or the BIOS may need an update. So now I guess I have to update my graphics card driver and the BIOS. Please advise on how I can do so.
