My eMachine T6520 Is Not Starting

 The power supply is one possible cause of startup problems.The eMachines T6520 model of desktop computer was released in 2005 and included the Windows XP Media Center operating system. If the computer does not start properly, the error could lie with a malfunctioning software service or hardware device. While a hardware error may necessitate replacing the offending device, eMachines and Windows both supply built-in options for resolving software issues at startup.

If the T6520 does not respond at all when the power button is depressed, or if the machine's power supply makes a whining or clicking sound, the error lies in the power supply's hardware. Power supply boxes may malfunction due to overheating or after several years of use. The T6520 power supply is replaceable in the event of a malfunction, and a new supply box may be purchased from any computer parts dealer. Reference a power supply's documentation for information on case size requirements to ensure the new supply will fit adequately in the T6520's case.

When the computer powers on, but does not boot the operating system correctly, Safe Mode is the easiest way to return the system's operation. Safe Mode is a built in feature of the T6520's Media Center operating system and can be accessed at startup by pressing "F8" when the eMachines startup screen appears, and before Windows starts. Use the arrow keys to highlight "Safe Mode" and press "Enter." Safe Mode disables many of the default services that start with Windows, including any that may be interfering with startup. Within Safe Mode, you can remove any malfunctioning services manually, or use the System Restore feature to roll back the system to correct operation.

If Safe Mode does not start correctly, advanced users can access the Windows Recovery Console to perform repairs. If the Recovery Console has been installed on the system previously, open it by selecting "Recovery Console" from the list at startup. Otherwise, insert the Media Center disc and press "R" during startup to access the program. Using command line actions, you can view and disable malfunctioning software on the system.

Microsoft's website keeps a list of available commands and actions available from the console. The T6520 comes with custom eMachines software for creating recovery discs. If you have already created these discs, they can restore the computer to the state it was in at the time of their creation. To use this option, insert the first disc into the system during startup and follow the instructions to restore the system. Note that this method will remove any personal information and programs added to the system since the discs were created.
