My motherboard is Intel 915GAV. where there are only one IDE channel. Bus: 800MHz Hard Disk: Samsung 80GB, 72000 RPM OS: WinXP Sp2 Processor: P4, 3GHz RAM: 256MB From few days, when I run some system utilities (like Norton Anitivirus) or even when I debug while programmiong in VB6, the Fan speed goes up and up and start making sound. Then I see in Intel Desktop Utilities, it say "Processor Zone Temperature exceeds normal range." Can it be the effect of any virus or someting else. please anyone tell how to solve this problem. If you need any more information please tell me. I will be waiting for your response. Thanks in advance.
