crashes, restarts, showing half ram and color on screen corner sometiomes line

my computer hp Pavilion dv2000 laptop has 1 GB of ram but only 512 MB in properties and freezes too much during the race and after which shows the blue screen and is also showing sometimes blue and only thin green the screen line and this line disappear sometimes and sometimes by flashing and sometimes contineously visible.please advise me what could be the problem and its solution.

Say hello to new aadilahmed. It is strange that you only have a single test, but this laptop is a few years old so maybe only, it came with a trial. However, it wouldn't hurt to go and run the test drive anyway. Failed or damaged hard disks can also cause strange problems occur.

In any case, I feel that the most likely cause will be the RAM. Fortunately, you can use another tool to check memory. The tool is called "Memtest86" and offers a CD image that you can burn and start Notepad with for diagnosis. You want to Save this file to your desktop and burn the image to a CD. Burn a CD image is a bit different from a normal CD burning so if you have never done before to follow these instructions so that you create a bootable CD.

You will also need to make sure the CD-ROM drive is selected as the first boot device. Here are the instructions.

  1. Go to the BIOS of your laptop.
  2. Go to the System Configuration section.
  3. Select "Startup Options".
  4. Make sure that the CD-ROM is the first boot device. The second should be your hard drive.
  5. Save your changes, and then restart the computer with the CD in the tray.
  6. Run Memtest86 and view the results.

Have a great day!

  • After Effects CS6 Crash - Film MXF + Keylight and Color Finesse

    Greetings community AEX,

    I'm pretty used to AEX crashing no aparent reason, but the frequency of the last series is a bit disturbing, and two of the stronger plugins (color of SA Finesse/Keylight) keep crashing when used. I am at a loss to know where to continue troubleshooting.


    Question:

    (1) I create a project in Adobe Premiere, and thanks to the Dynamic Link I replace a section of my sequence, by AEX composition.

    1 a) images that we use is MXF - 50mbit 4:2:2 acquired from a Canon XF300.

    (2) I use Color Finesse to adjust the image, the primary and the secondary color correction applied (we're doing chroma key work, and I find secondary helps give me a cleaner key when I can even the Greens)

    (3) I then apply the Keylight 1.2 filter, make the necessary adjustments and try to get an overview of my work in moving the playhead, or launch a RAM Preview.


    At this point, After Effects with either crash outright (if I touch the head or try a RAM Preview), or he will wait a few seconds and THEN crash.  HOWEVER, if instead of trying to move the playhead I just save my project and go back to the creation, the composition of the AEX plays very well in my sequence.  He did adjust my extremely difficult settings when I can't use the playhead to watch different images within the AEX.


    This question is highly reproducible, to the point where AEX will sometimes crash when trying to load the project file.  This is clearly struggling with the previews.

    Steps taken to solve (without success)

    -Restart the PC, delete the temporary files, check disk space, updates

    -J' tried to reset all default settings (CTRL + ALT + SHIFT), tried to clear all the cache/db, changed the location of the cache/db

    -Tried opening and creating a project outside dynamic links

    -System restart/graphics driver check

    -Curse to the computer

    -Turn off made in settings of the AEX, GPU switching CPU

    System Specs:

    -Recently reloaded my system clean installed Windows/Adobe, conducted all software/OS updates and generally little to the config which could cause a problem.

    -Intel Corei7 960 12 GB of ram

    -nVidia Quadro 4000

    -Intel 256 GB SSD + WD Black 2 TB.

    -Cache and previews are stored on the SSD,


    I am at a loss to know where to start or go here for troubleshooting more far.  The forums are so clogged with others experincing blocks in AEX (perhaps because only Adobe rushes their development cycles and explosions early software...), it is difficult to find something similar to what I am experincing.  Reloading of programs is an option, but uninstall, download and reinstallation is a pain, and I want this to be a last resort.

    Thank you

    -Greg

    Before you uninstall and reinstall once more, try this test first: transcode some of his problem for a codec lossless bindings.  I recommend the PNG Quicktime codec.  Then apply effects to them again in AE to see what is happening.

    The reason for this: your MPEG2 camera recordings.  It is not a true intermediate codec and compression is a group of images, rather than a single image.  The combination of Keylight and Color Finesse can be give AE fits.

    For this anthropomorphize, AE like to think image by image, but MPEG2 forces AE to think backwards and forwards over several frames, and it can be to revolt on you.  I hope you enjoy the technical jargon.

    Hi KevinRy,

    Welcome to the Microsoft Answers site!

    Unplug all external devices.

    Try to start in safe mode. If you can start in safe mode, and then do a system restore to restore the computer to an earlier point in time.

    Change the recovery settings to disable automatic reboot, if you are able to boot up to the desktop computer:

    1.

    Right-click my computerand then click Properties.

    2.

    Click the Advanced tab.

    3.

    Under Startup and recovery, click settings to open the Startup and recovery dialog box.

    4.

    Clear the automatically restart check box, and then click OK many times necessary.

    5.

    Restart your computer so that the settings take effect.

    Now, when you are going to close and a fatal error occurs, you will see at least and it won't cause an automatic restart.

    Please reply back with the error message you get because it helps us to resolve the error.

    Kind regards

    Hi @HPIsha

    I understand that you have performance problems with your laptop (speed, gels, etc.). I'm happy to help you with this.

    I'd take a glance on the following pages; There will be an overlap between them, but each is useful.

    Some software Applications may cause Windows to start or run slowly

    Windows 7 stops responding or becomes very slow after you connect to the Internet

    Set the performance of the slow system (Windows 7)

    It is possible that it could also be a hardware problem, but it is most likely too much software, loading or running in the background and thus more taxing your processor. These pages can help with this and other common causes such as malware and other cousins of software.

    Try these first, because these solutions are free. When it comes to hardware such as memory upgrades, you need to get the memory to do the upgrade, and it must be of the correct type to be usable.

    You can check this link for the Service Manual: Compaq Presario CQ42 Notebook PC and PC portable HP G42 - Maintenance and Service of Guide. In it, you will see the type and compatible variety.

    I hope this helps.

    It will be because the information can't come down from your internet connection fast enough for you to watch in real time.

  • I changed my ram and something is wrong

    Hello

    I am having trouble with my MacBook Pro. It's from early 2011, and it got REALLY slow down recently. Everything seemed to go well in general so I bought new Ram (2 x 4 GB instead of the 2x2gb installed). A few hours ago, I installed the RAM and the problem is that the computer is now super fast but it does that for a while then suddenly restart itself. Chrome and Thunderbird are also break repeatedly, sometimes after working for a while, sometimes they crash at startup.

    I tried to install El Capitan, but I get the message ' year error occurred "3 times already (I'm still on yosemite because my computer was so slow and almost died).

    I ran a program called Rember and I received the following message:

    "FAILURE: incompatibility of data to local address 0x0000000175271d80."

    "Actual data: 0x0000000175261d80.

    Is it possible that something is in conflict with the new ram I have installed, causing the failure of the system?

    A note: I bought a set of 2 x 4 GB of ram before and they did not work at all - my MacBook Pro would just keep rebooting. Now it's different because the computer running for a period of time (about 30 min to an hour).

    I hope someone can help me solve this problem.

  • Windows 8 explorer.exe crash/restart of cycle - all solutions?

    I was stuck in the cycle of crash/restart explorer.exe since September now and I am curious to know if there are definitive solutions. A fix would be nice...

    Details
    I installed Windows 8 Pro x 64 September 18 (reliability monitor information). The first instance of this crash/restart cycle was September 24. Then, I tried to find out what happened on this day: there was an automatic installation of an update of definition for Windows Defender (KB2267602 (definition 1.137.336.0).) Looking at the previous day, the following are installed:
    • Google Drive
    • Update Google Helper
    • Microsoft Hardware USB keyboard
    • Microsoft Hardware USB mouse
    • Generic Non Plug-and-Play monitor
    • AccuWeather.AccuWeatherforWindows8
    • InvokeITLimited.TableClock
    According to the reliability monitor, the problem occurs about fifteen to twenty-five times a week. The level of reliability varies from 1 to 4. (I don't know what the vertical scale means that there is no label.)
    In Event Viewer, this is a typical mistake:

    Every mistake I checked has the same code exception and faults of program and modules. (Besides - I tried to click on the "Event log online help" link but get an error itself is in error, but it's a slow minor compared to the issue of cycle explorer.exe crash/reboot.)
    I just started going through applications Windows 8 and uninstall, in hope, where is the problem. (One interesting thing is that the issue almost never happens when I'm not using my computer - it occurs most often when I save a file in a program (it is often with Photoshop Elements, but this is not the only program that seems to induce the cycle crash/restart).) At least the file I save is not damaged...
