My processor is 6 years old. its name is core 2 duo. i have recently changed my motherboard 2 years back. its name is intel DG41RQI. I have 2 gb of ram installed in my pc in one slot. My pc has become very slow. the cpu usage boosts upto 100% even if i open a browser like google chrome. i dont knw why this is happening and my pc makes a lot of noise. Will upgrading the ram from 2gb to 4 or 6gb make a diffrence. Please help. MY operating system is windows 7 32 bit.
