Power reset your desktop computer

Perform a power reset (or hard reset) of your desktop computer to clear information from the computer memory without erasing personal data.

  1. Turn off the computer.
  2. Disconnect the AC adapter.
  3. Disconnect all nonessential peripheral devices, such as printers, scanners, external hard drives, and USB flash drives.
  4. NOTE:
  5. Do not disconnect your mouse, keyboard, or monitor.
  6. With the AC adapter unplugged, press and hold the power button for approximately 15 seconds.
  7. After you drain the capacitors, reconnect the AC adapter. Leave peripheral devices disconnected.
  8. Turn on the computer. from here

Check to make sure that the power LED does not show you a white blink at all. Next download the Maintenance and Service manual for your computer from here

Page 96 tells you what those two blinks mean:

Red Power LED flashes two times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved

Possible cause

Thermal protection activated:
Air flow is restricted, a fan may not be functioning, or the heatsink is not properly attached

Recommended Action

1.Clean the air vents on the front, back, or
any other vented side of the computer.
2. Ensure that there is a 10.2 cm (4 in)
clearance on all vented sides of the
computer to permit the required airflow.
3. Ensure that computers are not so near
each other that they are subject to each
other's re-circulated or preheated air.
4. If the computer is within an enclosure,
ensure that there is proper intake and
exhaust ventilation for the enclosure.
5. If a message appears on the screen
indicating that a fan is not working, replace
the fan.
6. Ensure that the heat sink is properly
