Ok guys, I really need your help here. I have this annoying lagging problem. I don't know why, but when I start the computer and boot into Windows, every now and then my computer becomes all laggy. I check the CPU Usage and it goes high and down each second. Like when I play music, for example, when a song plays "Infinity" it would be like this "Iiiii...ffffin...iiitttyyy" with the annoying lag. I formatted by computer and it didn't help either. Please help me out here, thanks.
