Cpu Fan Noise A few times a day Hey frnds, need ur help. I have Amd 2800 processor with 512 ddr 2 ram, Asus motherboard, 333 Mhz Fsb. The problem is a starnge one. Shen i switch the system on in the mornin i get a starnge sound from the back of the Cabinet. I tried to find out where it is from and realised its from Fan. but if at that moment if it restart the system it vanishes and never re coccurs. till the time there is again a gap of 5-7 hrs in startin the system. I mean it occurs when the system is switched off for 5-7 hrs and then started. No problem with the OS or the programs. Pls suggest wat can be the solution.
