Windows 7 doesn't load afther install new RAM

Hi, i have buy for my Toshiba Satellite L655-1JV  2x4GB of RAM from PNY ( http://www.pny.eu/product/p-23-183-704/Laptop-Upgrades/Sodimm-DDR3-1600MHz-PC3-12800-4GB/ ) and afther i install the new RAM my windows 7 show's a blue screen error while starting, also don't allow me to start in any other mode like save mode and even won't allow me to go to recovery mode, but on bios i can see that the computer detects the 8GB of RAM.
I have reset bios and updated it, i have try to boot with only one slot of 4GB but always the blue screen error, i even have reinstalled windows and donne all again but always the wonderfull blue screen error. 
When i change for the old ones, 2x2GB, it runs always perfectly.
I will apreciate some help, tanks

Did you use the PNY memory configurator - Here
Obviously the ones you ordered are incompatable with your system or bad. Contact who you bought them from.
Crucial suggest these - Crucial memory for L655-1JV

  • Mac crashes regularly after installing new RAM

    My laptop crashes at least once a day ever since installing new RAM. It seems to be triggered by quitting programs, usually Firefox, Logic or Spotify. There was nothing else connected to the Mac that brought about the latest crash but I do use an Mbox 2 on a regular basis.
    Below is the last crash report and also the RAM profile. It's Kingston brand if that means anything.

    It's almost impossible to trace back the panic report to a specific cause, but it's highly suspicious that you started experiencing problems after installing new RAM.
    It's also strange that your RAM has no stated VendorID, Part Number or Serial Number.
    I would return this memory poste haste.
    Alternatively, if the DIMMs are from Kingston's ValueRAM range, just dump them in the garbage because that's where they belong. While you're there, look for any other RAM that someone else has thrown away - chances are its ValueRAM, too (hint: I have never seen a single ValueRAM DIMM work in any of my systems, so I avoid them like the plague - shame, since Kingston used to have such a good reputation).

  • Installed new RAM now computer wont start up

    I just installed 2GB of RAM in my iMac and removed the 512mb card it had originally.when i pressed the power button it beeps fast a few time then the fan starts working really fast. The screen doesnt turn on only the sleep light blinks as the fan runs. I replaced one of the new cards with the original 512mb card and it starts but when i check the memory the slot where the new 1GB card appears "empty" why could this be? did i install incorrectly?

    When you install new RAM you have to push much harder than you think you should. You won't damage the RAM, but you have t give a mighty push to seat it, make sure you hear a click.

  • 4 hrs later - Computer shut down after installing new RAM (mid 2007 Imac)

    Mid 2007 imac and I installed new Ram. It worked for 4 hrs then the Imac shutdown. The pressed power button but no power. Unplugged and replugged the power cord and 3 beeps sounded. I am wondering if it worked for 4 hrs or so, then why did it would it fail 4 hrs later?
    I am running the correct ram because in system profiler under memory - it said that everything was ok.
    Any ideas?

    or maybe the back tray wasn't tight enough?
    I re-installed it now and so far so good.... I pressed tight and in an upwards motion. We'll see what happens

  • Checking & installing new RAM

    Hi,
    I have a Pavilion dv7 product number VG420AV notebook with 4 GB DDR3 system memory (2 DIMM).
    I am wanting to upgrade the memory to 8 GB.
    Hp told me to buy a 4GB, 1600Mhz, PC3-12800 memory module (SHARED).
    I am not sure if I need one stick or two.
    How do I check to see if I have an avilable slot to install new RAM ,& how do I install new RAM in my notebook? 
    Thanks fo the help.

    That is a dv7t-3100 model. 2 ways to find out about the RAM. 1. Download and install CPU-Z and look at the memory tab; or, 2. Just pull the back cover off and look. 
    Here is the Service Manual:
    Manual
    Page 4-17
    And you do say you have 2 DIMM(s) which is all the slots available so to upgrade you are going to have to remove and replace existing memory.

  • Installed new ram, computer wont start up

    I installed 1gb of hynix ram. I tried setting it in different ways, but each time when i start up the computer it doesnt even get to the chime sound, the screen doesnt come on, my fan just runs loud and fast and nothing happens, but it starts up fine with out the ram. is there any hope of installing this ram?

    Generally if your computer won't start up after you have installed new RAM, either you have purchased the wrong type of RAM, or it is a bad module.
    As long as you are able to start up normally after removing the new RAM, and it is supported, it might just be a bad module. Contact Hynix to arrange for a replacement.

  • Windows 7 won't load after installing new Hard Drive and Recovery software

    HP G72 Notebook PC
    xz218UAR
    I guess a virus crashed my hard drive so I bought a new one.  I installed the new drive and loaded the recovery disks that I also bought from HP.  Apparently Windows didn't load properly and it keeps telling me to RELOAD WINDOWS.  I've tried starting over from Disk 1 but it's not doing anything different to fix it.  
    I removed the new hard drive and reinstalled it but it's still doing the same thing.  
    What am I doing wrong and HOW DO I FIX IT?

    Hi,
    Before trying the following, make sure you can still read the 25 Character Product Activation key on your Windows COA label ( 5 blocks of 5 alpha/numeric sets ).
    Assuming that this is just a problem with the Recovery process, there is a straight forward work around if you have ( or can borrow ) a retail Windows 7 installation disc that is exactly the same version as your OEM installation - ie if your notebook came with Windows 7 Home Premium 64bit this is the exact retail version you would need.
    If you don't have access to a retail disc, you can create an installation disc yourself using another PC - just download the correct Disc Image from the link below and use an application such as ImgBurn to burn the ISO correctly to a blank DVD - a guide on using ImgBurn to write an ISO to a disc is Here.  These Images are clean and from a well-respected source, however there are only limited versions available.
    Windows-7 sp1-iso-official-32-bit-and-64-bit
    Use the disc to perform the installation, enter the Windows activation key found on the COA Label when requested and when the installation has completed, use the 'Phone Method' detailed in the link below to activate the OS - this method supported by Microsoft and is popular with people who just want a clean installation of Windows 7 without the additional software load normally bundled with OEM installations.

  • Welcome window doesn't appear when installing CS5 on new imac

    I'm trying to install CS5 into my new imac but after I inserted the Application disc 1, nothing happens. the welcome window doesn't appear. No window to fill in serial #s, etc. Installed Acrobat with no problem though. Thanks.

    Thanks for your response Jeff. I'm still getting myself familiar with Lion and obviously handicapped with these tech stuff so pardon my ignorance. I didn't see the DVD icon the way I used to in earlier OS so just assumed it wasn't working the way Acrobat worked (the first DVD I inserted). Now, I transferred the contents of my backup drive onto my new imac and see both CS4 and CS5 transferred into the Applications folder. Does that mean the softwares are installed or do I need to install them through the DVDs? Don't want to accidentally screw up anything. If I just dragged and deleted CS4, does that completely remove it out of my iMac? thanks so much for your help.

  • Problem after installing new ram

    Just installed 1 MB of new ram. Everything appears to work with one very annoying problem that never existed prior to installation of ram. The problem is that the window moves slightly with any movement of the mouse. Not a great deal but enough to hide the menu at top of screen. I ran an Apple Hardware Test and all hardware passed. I changed the mouse but no cure. This happens with nothing running so I assume it is not software. It doesn't appear to affect the operation but it tends to make one sea sick with the up and down and side to side motion anytime the mouse is moved.
    Shure would appreciate any help with this.

  • Installed new Ram = 3 Beeps

    Hello! I wanted to max out my iMac (7,1) with RAM so I bought a couple new chips from Other World Computing. It came yesterday and I went home all excited to install it. I did, and on startup all I get is three beeps repeating endlessly. I opened the slot back up and made sure they were seated well and they were. Same thing. Put the old RAM back in and it started fine. Gah! How disappointing and frustrating!
    Here is the RAM I got:
    2GB PC5300 DDR2 667MHz 200 Pin SO-DIMM
    4GB PC5300 DDR2 667MHz 200 Pin SO-DIMM
    Any ideas would be much appreciated!

    Through an a separate email inquire with OWC, I got this response:
    +The 3 beeps from your Mac indicate it doesn't see any memory. This is not uncommon as Apple's RAM is a slight bit thinner than third-party modules, and as such, our modules need an a bit extra pressure to fully seat them into their rather tight socket.+
    +See if the modules can go another 1/8th inch (3mm) into the socket.+
    I'm pretty sure I seated the new RAM properly, but I'll make sure to check that as well.

  • Installing new RAM and need help!

    Hello everyone, I have this exact same computer model found here: http://wow-rebates.com/lenovo-3000-k100-57068352-intel-desktop-pc/
    This means that I have 4 slots of RAM, but 3 are currently being used by 1 GB sticks of DDR2 PC2-5300 @ 667. I just bought a stick of RAM today that is exactly the same as the other 3 (its a 1 GB stick of DDR2 667). However, after I installed it, it freezes at the first screen where it says "lenovo" in big white letters. It doesn't go any further than that, which is odd.
    Additionally, when using my new RAM stick with only 2 of the old ones (total 3 GB) it works fine, but whenever 4GB of RAM is in my computer it just isn't working properly. What might be causing my computer not being able to handle 4GB? Is there a dual channel option I have to enable or something? Help will be VERY much appreciated! =)

    Hummm, did you get into the Bios screen and check to see if the 4th gig is runnin? will pop up as 4 gigs in Memory. If not move the sticks around, if not get a new stick. If it show in bios then it's working.
    In Vista though you only get 3gigs max unless you run 64bit.
    I am using Kingston for $27   working fine.

    Hello Malith Ratnayake,
    After changing the old RAM by the new one, this issue occurs?
    If the issue doesn’t occur when you change back to use old ram, I think it is the RAM hardware issue.
    Please contact the hardware manufacturer for better support.
    Best regards,

  • MacBook won't even turn on after installing new ram

    I am using the 2010 MacBook (white 13 inch) I bought ram (two 2gb modules) and was going to install it. I removed my Original ram, but accidentally powered it on it the process (no ram was inside). I got a longed beep. I held the power button and shut it off. I then put the ram back in and it won't turn on. I don't hear any parts moving, no power, nothing. Yes I put the ram in right, an it's tight as can be. Its pushed in well. Help! I never put the new ram in!

    The new ram doesn't fit. The laptop won't turn on with old ram. It worked before I removed it now it doesn't. It's I'm there tight so don't tell me to put it in with pressure because I did

  • Help! Installed new RAM and now screen isn't coming on!

    Hi
    I'm in a bit of a mess and would be grateful for any help with this one:
    I have a Powerbook G3 500mhz Pismo that currently has a 512mb card in the top slot (Kingston PB100/512) that I installed about two years ago with no problems and an original 128mb in the bottom. At Christmas I bought another 512mb for the bottom slot – (Kingston KTA-PBG4/512 - This one is smaller than the first but it was the one reccomended by Kingston on their website for the Pismo).
    I have just got round to installing it after backing up my system and I have good instructions on how to do it (I have replaced the HD two years previous with no problems)
    Firstly I have to mention that just before I changed the RAM the laptop fell from a small stool (about 1.5feet high) onto carpet due to the unbalancing effect of taking out the battery/CD ROM. It landed on its edge where the power socket is. I immediately put it back together and turned it on to make sure it was ok - it came on fine and there were no problems visually, mechanically or otherwise, so I carried on with the installation.
    I installed the new 512mb card in the bottom slot and re-assembled but when I turned it on the screen remained black! From the computer itself, however, it sounded as if it had started up ok – there was the chime and the familiar sound of the hard drive at start up.
    To troubleshoot I removed the new RAM card and put back the old RAM as it was – this made no difference. I checked to see if the processor board was firmly in place or if I had dislodged any connectors by mistake within the area that I had worked but this made no difference. I also tried to re-set the parameter RAM and this made no difference.
    Because the laptop took a small knock prior to installation, I am not sure if that has caused something to come loose or damage of some kind but as I mentioned I did test it immediately and it worked, so it’s either a delayed reaction or the new RAM card has caused it. – (As mentioned there is a difference between the two 512 cards in both name and size but the smaller size of the newer one I assume just reflects advancement in technology and it was reccomended by Kingston!)
    If anybody has any advice on this I would be very grateful (and also, if anybody can point me in the direction of instructions on how to take the pismo apart to get to the connections to the screen that would be great – in case I have to do it)
    Many Thanks Barry

    SpottyFox,
    It sounds like you are properly seating the CPU card from your description, so I don't believe that is your problem. I am glad you checked the pins (I should have mentioned that as the next step if the reseating did not help). I cannot answer whether anything was damaged from your description of the pins; I have read where others have realigned bent pins with success so maybe your mileage will vary.
    Start up your Pismo, then shine a flashlight directly into the display; if you can see data being written to the display, just the backlight is refusing to light. If this is the case, check the inverter board connections. The inverter is under the clutch cover and powers the fluorescent backlight in the display. Enlarge the bottom picture in this link to see the inverter:
    http://www.ifixit.com/Guide/Mac/PowerBook-G3-Pismo/Inverter-Page-10-Inverter
    Check connections at each end of the inverter. Disassembly is not as extensive as this guide suggests. Support the back of the display, then remove the main battery, optical drive, lay the keyboard on its face on the palm rest, heat shield, and clutch cover...that's it.

    You might also connect the Pismo to an external display; failure here would suggest a more serious problem.
