My hp touchsmart310 PC will switch on but there is nothing on the screen ?


You can perform these steps even though the screen is blank.
  1. Turn off the computer, and then remove the power cord.
  2. With the power cord disconnected, press and hold the power button for five seconds.
  3. Reconnect the power cord, and then turn on the computer.
  4. Repeatedly press the F10 key about once every second for five seconds after turning the computer on.
  5. Wait five seconds.
  6. Press the F5 key. This restores the default settings of the BIOS.
  7. Press the Enter key. This accepts the changes.
  8. Press the F10 key. This opens the Save and Exit window.
  9. Press the Enter key. This saves the changes, exits the BIOS, and then the computer restarts.
  10. After the computer restarts, the screen should display the HP logo.
Hope it helps!

Dell inspiron 630m laptop. turned it on, programmes started up then died. turn it on now nothing on screen but there is power. no fan running all the time or overheating. think it might be the video card...


> no power
> no fan running

Remove the battery.

Disconnect the AC power adapter.
Use a "multimeter" to test the voltage/amperage output from the adapter.

Connect the AC power-adapter, and try to turn the computer on.
If nothing happens, then the computer's motherboard has "died".

Take the computer to a qualified technician, for professional trouble-shooting.

Nothing on the screen after power on


Turn on the computer and complete the following steps: Step 1: Check cable connections (If you can see the initial HP or Compaq logo screen but later lose the picture, you can skip to Step 2.) check the video cable connection on the back of the computer and on the monitor. Make sure that it is connected properly and the connecting screws are tight. Turn the monitor off and then back on again (while the computer is on) to see if an image appears. Some Flat Panel monitors have two similar power input connections placed side-by-side on the back of the monitor, which sometimes allows them to get confused for one another. One connector is used to supply power to the speakers with a separate power cord, while the other connector is used for the monitor's power adapter. Ensure that you have the monitor's power adapter cord plugged into the power connector and not the speaker connector. After you have reconnected the power cord, turn on the monitor (while the computer is on) to see if an image appears. If there is still no image, continue to the next Step. Step 2: Resetting the monitor At first setup, or under certain signal conditions, the monitor may not be able to switch to a new display resolution. Do NOT shut down or restart the computer. Instead, perform the following steps: Turn off the monitor using the Power button on the front. If the Power button does not respond, unplug the power cord from the back of monitor and wait five seconds. Plug the power cord back in. You should see the image from the computer on the screen.
