    Upgraded to 4GB Ram 64bit but doesnt work correctly


    Hi,

    I have recently upgraded my Dell Latitude D531 from XP 32 bit to Windows 7 Professional 64 bit.

    Previously I had 2.5GB of RAM, however having undertaken a crucial scan it said I can now have 4GB of RAM. So, I ordered a new 2GB and replaced the 512MB stick.

    Upon booting up for the first time and hit F1 to acknowledge that the RAM has been changed it loaded to the log in screen however I could see loads of white horizontal lines across the screen. I was able to login and the desktop appeared fine.

    I then noticed that the audio was coming up saying it cannot be found. It had a red cross through the symbol in the taskbar.

    I restarted on numerous occassions to no avail.

    I took the new 2GB stick out and put the 512MB back in and all loaded without any problems.

    Any ideas?

    I would take both sticks out and then try booting with just the new stick of ram in.
    Also make sure all cards are seated tight.

    Hi DarkXeno,

    Thanks for your reply. I was going to do this but decided to back off for now, as its a pain to take off keyboard etc.

    Instead I decided to look at the Bios. I was on revision A00 and realised there was A08 avaliable. I upgraded the Biso and all is working fine...so thats all it was. I somehow overlooked this.

    Thanks anyways.

    Did the system 'beep' for you, do you even have any power going in?

    Normally, if there was a memory issue, the laptop will give post beeps to indicate a problem. I would recommend giving a try of re-seating the memory and power it on again. The most common mistake with laptop memory upgrades is not seating the memory correctly and it isn't detected. The other common problem is something got unhooked when getting to the memory, and not hooked back up again, which would also cause some problems.

    No beep and yes it does have power both the baterry and plug to electricity the thing is that the laptop works great with either one of the 2Gb sticks and 1 of 512M... and yes the system recognize the memory cuz it appear on the BIOS screen 3Gb and in system info the 4Gb but only usable 3Gb...

    when both 2Gb sticks and i turn it on just sounds the hard drive and that's it! the screen is black and it sounds like the fans are working but that's all, no beep nothing happens next. on the other hand when either one of the 2Gb and the 512Mb there's no problem at all... it works normally... thanks again for being so cooperative with my issue!!

    Did you check before you bought the ram that it was compatible, did it match the ram you already had.
