I am using a Pentium, with windows xp service pack2, direct x9. My graphics card is geforce fx5500, forceware version: 81.98 My dell monitor is Dell E152FP I want to ask why my brightness/contrast screen of the monitor keeps popping up? Is it due to viruses or malware? (which I dun think so as my virus, spyware are up to date) Is it due to my monitor malfunctioning or graphics card? Is it because I never install upgrades of geforce? Please help.
