Video randomly resizes the maximum size on my HP P6740F desktop computer

My wife has a PC HP P6740F.  It is currently running Windows 7 Premium.  His computer is connected to a ViewSonic monitor.  It uses the Microsoft Comfort Optical Mouse 3000 and the Microsoft Natural Ergonomic Keyboard.  There were no changes to the computer hardware.

We had our computers for about 15 or 16 months.  For the last month at random times its screen will grow in size until it reaches the maximum.  She can bring to the size by holding the CTRL key and using the scroll on the mouse wheel.  She played a game called Jewel Quest and it makes certain demands on the video card.  We do not know if this problem is related to the video game or another problem.  I asked him to start her computer after she ended the game but that has no effect.

I also have the same computer and I have not had problems.  I do not play video games, and that's why I thought that it might be related.

I wonder if it's a known problem or how to fix.

Thank you.

Hello Abbey_Normal,

I would venture to say that this is not a known problem or you would go into the same problem as well, but it may be a problem with the driver that is currently installed on the computer.

1. go to the control panel

2. Select system and security

3. then choose Device Manager

4. under the terms of graphics card would be the monitor drivers, do a right click and uninstall

At this point your monitor will turn off and we need allow Windows reinstall the driver, but we need to restart the computer.

To restart

1. press the Windows key

2. press the right arrow key twice

3. press r

After the reboot it should log on Windows as usual and re-install the drivers. Check the device to see if everything works correctly at this time.

    What is the maximum size of the image (in pixels) a height that supports the Muse? I noticed that if the photo is too high, reduce the Muses.

    Thank you

    If you place an image with a height or width greater than 2048 pixels - in Muse - Muse will scale the image down proportionately, limiting the larger size to 2048.

    However, if you want to use the picture to its original size, you can move the image to the desired size by dragging handles to resize, or by entering values for height and width in the strip control on top. After that, go to the active panel and locate the image, then right-click on this image in the active panel and choose "import of large size. Which would bring the image lost the original image information.

    Hope that gives you clarity on what you wanted to know.

    See you soon,.

  • Hi, my places.sqlite file size is 30 720 KB I reached the maximum size, is there a maximum size for this. Visited links are is more changing color.

    Hello
    My places.sqlite file size is 30 720 KB I reached the maximum size, is there a maximum size for this.
    Suddenly the visited links don't change is no longer the font color, that I prepare for an exam, I need visited issues to change color, to follow up on issues that I ended. But if I delete a few days of history, then again once, most visited links change color and then it stops, it seems that something is getting full and not able to accommodate more? Why my visited links don't change color after a number of visits? I would like to make a back up of the file places.sqlite. So I tried everything to remove the profile, uninstalling reinstalling, creating a new profile, and then copy paste places.sqlite etc, but as mentioned after a few visits, visited links is no longer change color, if I delete a few days in history and then a few visits is again change color and then stop again, so what should I increase so that my quota of visited links is increased , I also tried tweaking about: config and there has been no result. Although I was not really convinced that _pages growing brower.history_max (don't remember the name, but I'm sure you get the idea) will help.
    Seems that while my visited links change color, quota is met and only if I delete the history of a few days will I get some links most visited to change color. Can someone enlighten us? As mentioned that my places.sqlite file size is 30 720 KB so I think maybe this has something to do with it? Would be very grateful if someone could help me. Thank you.

    Sorry it is not looking good.

    1. Unlike bookmarks history is not saved in Firefox.
    2. There is a possibility using Windows.
    3. Sync is not expected to back up things until the synchronization server
    4. If places.sqlite does not sort itself you may have to re-create remove it. You will lose your history, but can still access indirectly IF you have saved a copy of the appropriate
    5. Different databases to try to create new profiles
    1. History
      is rather less robust than bookmarks, you should deliberately somehow return it upward, but it's too late now
    2. Earlier versions of Windows
      This is really the last chance. Make sure you have some places.sqlite you saved. Always before and after any attempt to restore the backup. Windows must be able to provide a previous version. One of these versions may be usable as is; or can be used after a repair with housekeeping. Of course, this is not the latest version but it should help.
    3. Sync is not a server backup service.
      Sync is intended to save on another device, no backup is the fact that the second device then contains synchronized information. IIRC Sync development ceased, and the replacement when available may include a server backup option.
    4. Recreate the database of bookmarks (including history)
      Unfortunately, recess can only use saved bookmarks, there is no saved history to use. Once the database is re-created, it will continue to store the history but it loses the existing history. This time take steps to save on a regular basis.
    5. Use the new profiles for database testing.

    To simplify comparison of the results of the database different files create one or more new additional profiles. Then try to smash the places.sqlite file into the test profile with any other places.sqlite, you want to try. Allows you to directly compare the databases, without seeking to use sync and without changing the Firefox profile work unnecessarily. You can keep a reference profile of studies with the best of the profiles of any shows results of history; According to the best recreated or corrupted database is.
    • Use the Profile Manager to create and delete profiles Firefox
    • CARE, do not rename or delete profiles created once or use anything other than empty folders when they are created. Don't nest in the other profiles. (At least until you know exactly how it behaves - post back if you never consider such actions)
  • What is the maximum size of HARD drive, I use in my dc7600 CMT

    I use a HP dc7600 CMT, which works well after the upgrade to a Samsung 128 GB SSD Intel Pentium D 3.4 GHz, 4 GB of RAM and an AMD Radeon HD 6450. I'm under Win 8.1 Pro x 64, with the most recent upgrade and have absolutely no problem. Now, I want to add a second internal HDD and I wonder what is the maximum size that I can go to. I can't go up to 2 TB, or am I limited to a lower number? 1 TB? 500 GB? 250 GB?

    Will be happy to help here, especially if he actually tried to apply in practice.

    Thanks in advance.

    Best regards

    Hello:

    In theory, you'd be limited to 2 TB.

    The biggest HARD drive I have ever installed in my dc7600 CMT was a 1 TB of HDD, so I can't confirm that a 2 TB drive will absolutely work.

  • Portege R100: Question on the maximum size of HARD drive

    Hello

    I understand the internal player on the R100 is an ATA5 (Enhanced IDE), I've only used the IBM (now HGST) readers, they do a decent-sized on ATA6 disc, I guess, it will take the player that will support ATA5 as the controller on the R100 is ATA5 only.

    As for the size, what is the maximum size can I ride in this unit?

    The orginal is 5.4 width x depth x 7.9 height 8 mm. Can I assume all 1.8 inch drive will fot or is it a mine field?

    Thank you very much
    Ashley

    Hello

    AFAIK the R100 was delivered with a 30GB and 40GB HDD.
    I found an info that the hard drives are compatible:

    HDD1422: Width (mm) 54.0; Height (mm) 5.0 0.15; Depth (mm) 78.5 0.3
    MK2003GAH: Width: 54.0, height: 8.0, depth: 78.5
    HDD1384: Width: 54.0 0.2, height: 8.0 0.15, depth: 78.5 0.3

  • Satellite Pro 4600 - what is the maximum size of HARD drive?

    My age Satellite Pro 4600 has a 20 GB HARD drive. These are now very difficult to obtain, does anyone know if superior capacy HDDs can be used and, if so, what is the maximum size of the HARD drive.

    (Despite his age that I always use the Satellite Pro for some jobs).

    Hello John

    Satellite Pro 4600 is old enough for laptop and it is not easy to find the exact info. The fact is that this laptop comes with 10 and 20 GB hard drives.
    My opinion is that you can use 30 or even 40 GB HDD. I think that 30 GB new HARD drive should be enough for your some jobs.

    What do you think?

  • Satellite L40 - what is the maximum size of HARD drive?

    I have a laptop Toshiba Satellite L40, model number PSL4CL - 001 with 80 GB HDD (SATA) 00C. I need to buy a new bigger hard drive, but I don't know the maximum size that I can use my laptop?

    Can I get a new one with 500 GB or I shouldn't buy one more 250 or 320 GB?

    Hello

    Theoretically, you can buy each HARD drive you want. Your laptop is equipped with a SATA interface for HARD disk and there is no limit of capacity as on the old IDE interface. So, a 500 GB model should work correctly on your laptop.

    If you buy a new one make sure that it s a portable 2.5 HARD drive with SATA interface. All that s! :)

    I hope I could help a bit.

    Good bye

  • What is the maximum size of HDD compatible on Satellite A300 PSAG4A-02M00M

    I was wondering if anyone can tell me the maximum size of hard drive that can handle a PSAG4A-02M00M and max running at 5400 RPM, (because I don't want it to be slower than that).

    And what specifications for disk replacement? (IDE, etc.)

    Thank you

    Hello

    As far as I know the laptop supports the SATA HDD controller and you must use a SATA 2.5 HARD.

    You should be able to use any HDD SATA controller SATA HDD is not limited to any size. I think that the BIOS should also support a 320 GB HARD drive or more

  • Equium L20-197 - what is the maximum size of HARD drive

    Hi all

    I recently bought an Equium L20-197 and I thought to install a larger HARD drive.
    I wanted to know what the maximum size of HARD drive that can be installed on an Equium L20-197 (I guess it's 120 GB, as it is on the L20-187 but I'm not 100% sure)

    I have also been seaching for the IDE drives and found a list of sites who have PATA, ATA100 etc. are also the IDE drives? (I checked the wiki and articles all point Yes, but a little more confirmation would not hurt)

    I was also wondering if the HARD drive I install must be brand toshiba (or if it even makes a difference).

    Thanking you in advance for any help you can provide.

    Hello

    Equium L20 is very similar to the Satellite L20.
    Search here in the forum for similar issues. If you want to use the advanced search option, you will find a few useful headings.

    I know, it's that you can use the 40 GB, 60 GB, 80 GB and 100 GB 2.5 IDE HARD drive supporting the UDMA100

    The problem is that there is no official information on the maximum size of HARD drive on laptop series different. If we can only speculate on the supported formats.

    But I found it here in the forum:

  • HP 14-r025tx: what is the maximum size of hard drive I can replace my default one? & other hard disk performance issue

    My default hard disk is almost full and I plan to update. What is the maximum size that this model could overcome? Very well is 2-3 to?

    Another question.

    I replaced my optical drive to a box with a 250 GB SSD HARD drive inside. I installed my new operating system here, and makes the default boot drive. The default value of HARD drive that comes with the laptop is my backup drive. This is configured by okay?

    or

    Do I have to put my SSD on the default HARD drive space and put my 2 to/3 TB harddrive on the caddy for maximum performance?

    Hello

    1. in theory, you can get 2 TB or TB but 1 TB has better peformance.

    2. you cannot boot from the caddy. My suggestion: use for normal Bay and 2 TB SSDS in the caddy. You both what you want.

    3. as (2) above.

    Kind regards.

  • HP Jet 13-c002dx: the maximum size of the map of adapters support

    I'm sorry to repeat a question already asked the existing question was marked as "resolved", but has not answered the question.

    The question was: what is the maximum size of the microSD, supported by this device? The answer, in so many words, was, 'well, it really works with the adapters of 64 GB card. I have not tested with the 128 GB card, so I don't know. »

    The original question still received no reply, which was what is the maximum size supported. What is 64 GB? Or is this 128 GB? (And the limitations of size due to hardware, software, or both together? Format SDXC UHS-1 the so-called supports more 128 GB, even if perhaps not for micro size?)

    Best Buy could not find this information. I was not able to find a certain answer online either.

    I bought a map of UHS - 1 128 GB adapters and don't want to remove the package unless I know WITH CERTAINTY that the device will support it. Otherwise I'll lose $80 + $. At the moment, with her, sealed in the package, I can always take back and exchange it for a smaller card.

    Thanks for your help.

    I just, I couldn't believe that this little piece of information that is important has not been printed in the user's Guide. Worse still, no one seems to know the answer - not the Geek Squad at Best Buy (for which I pay), not here on the forum or in the HP Solutions guide. Finally, I appealed to someone higher in the chain (I won't say how, because I don't want their flooded of calls!), because it really was an oversight in the User Guide. Less than an hour, I received a phone call and was corrected thanks to a support person.

    Thank you, HP! I think that they won't really the extra mile to help me solve this problem.

    Therefore, the maximum size that this HP 13-c002dx stream will support 64 GB. I took the card of 128 GB unopened back to Best Buy today and I bought the 64 GB.

    (Advice to people looking for a computer/phone/Tablet Accessories: do your homework before shopping at Best Buy.) They will tell you anything to make the sale.)

  • What is the maximum size of hard drive, which can be installed in a pavilion d4790y desktop computer?

    What is the maximum size of hard drive, which can be installed in a desktop pavilion d4790y?

    It would be a secondary drive, not the boot drive.

    The operating system is Vista Home Premium, 32-bit.  The version of the BIOS is 5.08.

    Are there any changes or upgrades that would allow an internal hard drive 3 TB to install?

    Here are the specifications and configurable options for your desktop HP Pavilion d4790y and here are the specifications of its card mother P5BW - THE (Basswood2). Based on the specifications and the age of the computer, I would expect you to use a hard drive 3 TB as a secondary drive on Windows Vista (DISPLACEMENT SP1 or SP2) and Windows 7. Formatted as MBR would require the drive to use with a minimum of two partitions. Formatted as GPT would require only a single partition. In no case will you be able to use the 3 TB as a boot device drive because your computer does not support a UEFI BIOS that allows booting from a GPT formatted disk. No changes or updated should be held.
