Having problems with your PC Desktops ?

My monitor is flashing blue on and off at the power button

Answers :

If the screen is black, then there is no data going from the computer to the monitor. If this is the case, your computer may not be starting properly or you may need a new videocard.\015\012\015\012
\015\012If your computer is not starting properly, you can try re-seeding the ram (taking it out and putting it back in). \015\012
  • Open your case remove the power cord from the PC
  • \015\012
  • touch some metal on the case to remove static
  • \015\012
  • take the ram out.
    Note: if you have a white eraser, this would be a great time to clean off the gold leads on each stick. Use the eraser (as you would normally) on the leads to make sure they are nice and bright. Be careful not to touch the leads with your hands.

  • Put the RAM back in,
  • \015\012
  • reconnect the power and turn your computer on.
\015\012If this doesn't work, and you have many sticks of RAM, try connecting using just one at a time to test and see if a stick is bad.\015\012
\015\012If you have a stand alone video card, try re-seeding it just like the RAM. You can also clean off it's leads in the same way as the RAM.\015\012
\015\012The only other thing it could be is a dead motherboard. To check for this, remove the ram and turn the computer on. If it beeps, it's working and something is wrong with either the ram or graphics card. If it doesn't, you need a new motherboard.\015\012

The power light blinks solid blue every four seconds or so (it?s off in-between). The screen is blank. None of the buttons on the side function (such as ?menu?).

We?ve always (as in years) left the monitor on (w/ a screen saver) but for whatever reason turned it off for four days when we went away recently. The monitor would then not turn back on.
