Hi and welcome to fpch.

 

Try putting the old RAM back in.

If you still get nothing - put the old RAM in one module at a time ( trying to boot up after each).

 

If it will not boot now - when you switch on do you get any POST beeps?

Did you used to get a beep when you switched on? ( one is normal ).

The MOBO having power at the time is not an issue, as long as the PC is off then its fine, if the PC was on as in CPU running etc, you would have heard some sizzling as you put the RAM in and then a sharp tingling feeling :eek:

 

When you insert new RAM it is best to clear the CMOS (But if the system is overclocked or you have any specific setup take note of the changes as these will be lost)

 

Are you 100% sure that you purchased RAM that is compatible with the MOBO as in the speed and size (GB)

Hi guys thanks for the quick feed back

 

 

I have checked the new ram and it is not the same

 

 

Tried fitting the old ram one slot at a time but still the same

 

 

And there are no system beeps

Disconnect all external hardware ( printer etc )

 

Strip the M/board of all cards ( RAM / sound / ethernet etc etc ).

 

Disconnect the power and data cables to hard drive and dvd drives.

 

Leave only the 20(4) pin connector from the PSU connected.

 

Switch on.

If you have an onboard speaker or the case speaker connected you should get POST beeps.

Do you?

 

If not - it looks as if you have a problem with either the PSU and / or M/board

It was stated in the first post that the fans and lights all appear on.

 

Naz, insert the old RAM and then pull the CMOS battery (the small watch battery) out for 30 seconds (while the PC is off) and then re insert the battery and then power on.
