Dimension E521 problem.

Dancor

It powers on, but no response from the monitor, keyboard or mouse. The red light on the mouse flashes once then nothing. Very load fan, no beeps but the numbers at the front of the case, 3 and 4 are flashing. All lights on the board seem fine, net card etc. I cant find any symptoms for the numeral lights flashing although im sure it has to do with the problem.

Anyone got any ideas?

Hi there.

Lights 3 and 4 on some dell models indicate memory errors. I'm unsure for your model. Perhaps google dell e521 diagnostic lights.

If you have 2 sticks of RAM try remove 1 and if that doesn't work swap them and try the other.
For errors like this it will take some troubleshooting. Hopefully you can get your hands on some spare parts for testing if required.

You can run a memtest on the memory.
If your memory is OK, It could also be the graphics card or PSU to name a few.
Best of luck
