i read that if u use windows Xp , it cannot detect 4 ram slots.. max 3.. vista can detect 4 slots.. so lol

anyway tumpang thread ya.. recently sometimes my computer when i startup, i get thet 3 endless loop beeps saying ram not detected.. then i take out my ram, use eraser to rub and blow the dust in the ram slots.. after that than can use.. but after 3-4 days the beeps come again and i have to remove the rams again.. any idea? motherboard or ram problem?
