RAM installation

  1. I'm facing a bizarre problem. I installed a new 512 Kingston DDR ram into a computer- everything says it should be right right type. Matchd the old 128 to a T in specs except for the speed, of course. When I plug everything back in, the monitor won't recognize that the computer is turned on and stays in inactive mode. It does recognize that it is plugged into the cpu though.

    Any advice????

    Hello and welcome to Techspot.

    It`s never a good idea to mix ram brands/sizes/speeds as this can cause problems.

    Take a look at this thread on Ram troubleshooting.

    Well the thing is

    Everything is the same, minus the 128/512 difference. So, out of curiousity I reverted back to the 128 and still no luck- blank screen. I know everything is working (minus monitor) as I hear windows start up and hear the new mail notification.

    Any other suggestions?

    Check that you`ve not inadvertantly disturbed the graphics card, when you replaced the ram. In fact, check that everything is properly connected and seated properly.

    Sorry if this sounds dumb but, if your mobo has onboard graphics and you have a separate graphics card, make sure you`ve connected the monitor to the correct graphics card. I`m sure you`ve already checked this, but stranger things have happened.

    Regards Howard :)

    Good point Howard. It's always a good idea to double and triple check your connections any time you are changing things inside the case. Things can easly become loose by an inadvertant bump.

    Thanks Howard and poertner- I double checked everything and nothing worked. Fortunately I have some guys on base that have some time tomorrow to figure out whats going on with it.

    Do you have the 128 and the 512 in together? If you do, run only one at a time.
    hope this helps

    You know I had something very similar happen one time. After much frustration I eventually realized I forgot to plug the monitor back into the vid card instead of the mobo's. It was one of those mistakes that was so simple it was overlooked.
