The past few days I've been through some computer crashes where the system shuts down completely. Usually this occurs suddenly but sometimes I receive an error message before it shuts down. I have received two so far: * A blue screen shows up that says an error has occured in NTFS.sys and the system will be shut down. * A blue screen shows up that says a physical memory dump has been done and the system will be shut down. Usually the system shuts down immediately, as though somebody has pulled out the plug. The crashes often happen in sequences, after the computer has been running for a while. Upon startup I sometimes receive the error message "overclocking failed" before the computer goes to Windows. I'm wondering what causes these crashes. I've checked the temperature on my CPU and it reports a temperature of 100 degrees celcius / 212 degrees fahrenheit. The fan's rotation speed is 2700 RPM. The processor is an Intel Pentium 4 3.2 GHz and the temperature seems kinda high. Is it possible that the crashes are related to an overheated CPU or should I be looking at something else?
