Having problems with your Dell Dimension E521 PC Desktop ?

My Dell Dimension E521 won't start up and has a flashing 3,4 code.


Answers :

Can you check your bios page on startup? Do you see anything on the screen when you first powerup? If you see nothing and only get the flashing lights you may need a power supply.

\015\012You may also have a bad HD or perhaps loose memory chips.
\015\012
\015\012You can start by checking the bios for an installed hard drive and memory. If you see those and then it stops booting. Check the power supply.
