After the previous blog about basic PC maintenance and you find your desktop computer is still just shutting off after a few minutes then you may want to consider if the power supply is going out. Changing the power supply is not that difficult but safety should be number one in concern.

Dallas' PC Virus Doctors Recommendations:
- ALWAYS, disconnect the power cord from the computer along with all other USB plugs, monitors, keyboards, the mouse, modem, etc.
- Remove the one side of the computer that allows you to unscrew it from the back or has a lever for the user to lift and remove the designated panel.
- Now view the power supply located on the rear computer panel and located against the upper case; the supply is connected by about four phillips screws on the rear panel.
- If the power supply is rectangular, almost square, then most certainly it follows the 'form factor' and any good power supply with the same wattage rating should work well and fit 'true to form'. If you find two power supplies with similar rating see which one is heavier and choose it.
- Before removing the old power supply the next step becomes obvious to the most novice computer repair tech: documenting where the plugs go from the old power supply into the mother board, hard drive and other removable drives like a floppy-drive or cd-rom.
- After documenting the plugs' whereabouts then remove the old supply and replace it with the new power supply.
- Attach the plugs from the new supply into the motherboard and drives.
- Replace the cover and plug in all the peripherals.
- Turn it on.
- If the computer does not shut down and reboot then one knows it was a faulty power supply shutting the PC down, not software problems.
