[Solved] Added memory and computer stopped Working!

I have a DC 5850 Small form factor computer, and just added 2 Gigs of memory, and for some reason computer would not come back on! ...everything sounded like it was OK, but the monitor stayed Black, I removed the sticks and it started working normally. I have checked the bars and they seem to be the correct ones from Crucial Memory. Any Ideas what this might be?

 

Hello What I received from Crucial is 4GB Kit (2 x 2GB) DDR2-800 UDIMM : CT824415 and there are 2 slots left in the PC for those bars. The Ram it presently has is 2GB but I don't know their specifics, I will have to pull them out and look if you need those details.

 

Hi John.
Run the Crucial system scanner to determine the right Ram for your computer.

I ran the scan before I purchased, and I just ran it again to confirm, but it states compatible memory is Crucial 2GB DDR2-800 UDIMM which seems to be what I received.

 

No I have not done that! ..the Original HP Ram is 1 GB per bar. ..You say I should pull those out and replace in their slots the New Crucial 2 GB bars?

 

OK will do! Thanks

 

Hello Cindy, I switched the new bars into the old memory slots and it is working! plus Its showing 4GB where before the PC was only 2GB. ...Do you think I should attempt to add those two old 1GB bars to the other slots?

 

Just add one first, then if it boots, add the other.

 

I added one as you suggested and it booted fine, so I added the last one and it's working normally! and showing all of the 6GB in Computer properties. As always you Folks are lifesavers! ...Thank You Cindy, Dougie & Seth.

 

You are Welcome, John.
