Mine is a Toshiba Tecra M11 laptop with Windows 7 Enterprise installed on it with corporate applications. Starting a few weeks back - the unit started to freeze up once every 2-3 days. Starting today - it is freezing up almost every 90 minutes.
When the unit freezes - the display remains fine but I lose my mouse and keyboard. Both internal and external mouse and keyboards lose power. The only option I have is to forcefully power it down and turn it back up.
One thing I noted is that once the unit freezes up - fan starts to run really fast. When the unit runs normal - fan runs at normal speed
I have installed CPUID Hardware Monitor and didn't notice any significant change in any temperature. I have also checked event logs and there are no issues reported when system freezes up.
Any help will be appreciated.
