I have shutdown problem in my desktop system.
I have a Core 2 Duo, 1 GB RAM, Windows XP SP2.
I suspect that the problem might be due to virus so I have updated the virus definitions (Microsoft Security Essentials), scanned my system completely. The issue was not resolved, so I installed Windows XP SP3 alone. Still I have same problem. Then, I installed Windows 7. But my shutdown problem not resolved.
Does the above problem occur due to hardware problem?
Note: My system has a CMOS checksum error: "CMOS check sum error" while booting
