I have a PIII 866. My system is having a problem from many time. When it is running it makes sound like the fan is being touched with some object . Also it gives me cmos checksum error when i boot it. I have a littleedge of systems and so i chhanged the battery of the motherboard as it may be a reason for the cmos checksum error. But it also doesnt help.
What should i do. Please tell me
