Dell.com features an online Quick Test that can diagnose many problems with a Dell computer. In addition, the website features an online tool allowing anyone in possession of a Dell computer to input the service code listed on a sticker attached to the computer and display information such as the computer's warranty status and original hardware configuration. A Help by Topic section includes links to information about common problems such as POST failures, boot failures and audio issues.
Anyone experiencing trouble with a Dell computer who is able to view Dell's website can perform a Quick Test by clicking the Go to Quick Test button on the Top Resources page in the support section. This test mainly checks for hardware problems that do not inhibit booting the computer up and getting online, such as bad sectors on a hard drive or defective memory. If the test detects hardware defects and a check on the warranty status indicates a warranty is in effect, the website issues instructions for obtaining warranty service. If the computer cannot connect to the Internet to perform a Quick Test, clicking the No Power, No POST, No Boot and No Video link in the support section displays instructions and videos to help determine the cause.
Problems with the computer's operating system often cause undesirable symptoms. The Support Library features a section called Windows Operating Systems from which users can click the computer's operating system to display topics such as Perform Microsoft Windows Maintenance, Computer Turns on But Does Not Launch Windows and Windows 7 System Restore.
