Solving computer problems Diagnosing problems If you have a problem with your computer, you can test it by using PC-Doctor® for Windows. To run PC-Doctor for Windows, do as follows: 1. Click Start. 2. Move the pointer to All Programs (in Windows other than Windows XP, Programs) and then to PC-Doctor for Windows. 3. Click PC-Doctor. 4. Choose one of the tests, from either Device Categories or Test Scripts. Attention Running any tests may take up to several minutes or longer. Make sure you have time to run the entire test; do not interrupt the test while it is running. The System Test of the Test Scripts runs some tests of critical hardware components, but it does not run all of the diagnostic tests in PC-Doctor for Windows. If PC-Doctor for Windows reports that all of the tests in the System Test have been run and that it has found no problems, consider running more of the tests in PC-Doctor for Windows. If you are preparing to contact IBM for support, be sure to print the test log so that you can rapidly provide information to the help technician.
