Performance Problems

The computer becomes hot -

„In a 35oC environment, the certain areas of the computer’s back case are expected to reach 50 degrees.

„Make sure the air vents are not blocked.

„If the fan does not seem to be working at high temperature (50 degrees Celsius and up), contact the service center.

„Certain programs that are processor-intensive may increase the computer temperature to a degree where the computer automatically slows down its CPU clock to protect itself from thermal damage.

The program appears stopped or runs very slowly -

„Press CTRL+ALT+DEL to see if an application is still responding.

„Restart the computer.

„This may be normal for Windows when it is processing other CPU-intensive programs in the background or when the system is accessing slow-speed devices such the floppy disk drive.

„You may be running too many applications. Try to close some applications or increase system memory for higher performance.

„The processor may have been overheated due to the system’s inability to regulate its internal heat. Make sure the computer’s ventilation grills are not blocked.
