Dear Sir, I have been trying to figure out what went wrong with the BIOS for DELL OPTIPLEX 466/L PC. When I switch it on, the screen is somehow divided into three vertical sections. When I switch it on and off again, it says SYSTEM BIOS has been destroyed. Could you kindly send me the BIOS for this DELL PC as specified above. Looking forward to hearing from you soonest, Allan D.
