Problems with my desktop computer!

I have a HP a1720n and it sat in my closet for about 6 months and finally, I got it out and hung.  When I turned it on it beeps for 2 dry and stopped, then it beeps for 5 seconds and stopped, then start again.  I have to hold the power button to turn it off.  It turns on sometimes and after about 10 minutes it will freeze and I have to turn off the switch.  What is c?  I'm trying to get rid of the computer and I can't if it does not work.  Please someone help me

I would like to...

Unplug the power cord.

Open the side panel.

Clean the dust in the fan zones.

Remove the memory modules.

Replace a module of memory (we'll call it memory 1).

Plug the power back in and turn on.

It emits beep with memory 1?

Disconnect the power supply.

Remove the memory 1 and insert the memory 2.

Plug the power back in and turn on.

Memory 2 emits beep?

I think you can take it from here...

Basically you try to find the faulty hardware component or a bad connection card. Keep when the cards until you find the bad boy. Sometimes, simply reseating a card taken is the problem will be solved. If all goes well, it is not the motherboard.

  • Desktop HP Pavilion - p7 1549: problems with my desktop HP Pavilion - p7 1549

    I have problems with my desktop computer, do very strange things.  A few weeks ago, it would not start and complained no found boot device.   I went into the bios setup and just reset the values by default and it worked for a few weeks.  Now it does not start at all.

    I tried to access the system with F11 recovery and he complains about some secure boot options, I tried to disable secure boot and it still does not work.

    I tried to put another disc in and install Windows on it, but I could not.  Is it possible to upgrade the BIOS by booting to a USB port?  I tried to download the new bios file, but it didn't do anything after that I ran it (he didn't not create a folder for me).

    Everything seems really slow, takes a few minutes to get into the bios or boot options.  I took out the hard drive and plugged into another computer with an external enclosure and my other computer recognizes the drive.

    I tried to do a system restore to factory default start repair/restore and all have failed.  I deleted very recently on the main partition on my drive to try to install 10 Windows on the drive.  The computer appears to be frozen for a long time before continuing with the guests of installation.

    I took out the CMOS battery and you press the power button with the computer unplugged.

    Don't know what else I can try, I'm starting to think that something is wrong with the motherboard.  The computer starts up fine and I can boot a USB Windows install and the keyboard, mouse and video work.

    I think the next thing I will try is tent to start on a standalone update or ubuntu USB boot bios.

    Not really concerned about my data, I just want to get this computer working again.

    Any suggestions are appreciated, thank you.

  • Problem starting my desktop computer

    Hello

    I would appreciate if you could help me on this.
    A few days ago I took my uncle s old Acer Aspire T180 upgrade. It did come with a hard drive, but I got an old Toshiba hard drive which I plugged it in to see if it works.
    (Card: 512 MB of RAM, AMD Athlon)
    Problem 1) is where the problems began to occur. Startup Repair has not solved the problem. I tried to use the system repair and restore backup options, memory diagnose or Toshiba HDD repair and other options failed.
    I thought that it was the hard drive, so I ordered a new hard drive Toshiba from Dell.
    Problem 2) after installing the new hard drive, it says «verifying DMI pool...» Disk boot failure. "
    After searching online, he leads me to the next solution I need to reinstall Windows 7.
    Problem 3) I found the product key on the side of the desktop "Windows xp media Center 2005" and I tried to get on Microsoft, but it was rejected.
    Then I found a download link for "Windows xp media Center 2005" I thought was an OS like windows 7 and downloaded on a usb key.
    Problem 4) using the. ISO file, I tried to boot to the desktop through F12, however, the system is stuck on the message «verifying DMI pool...» »
    These are the problems I have encountered, and try to counteract the problems led me to the other issue.
    Please help me.
    Thank you
    Salman
    PS. I don't have the disc of windows 7 or any other disc that came with the desktop computer.

    And my product key does not work.

    Hello

    The most common cause of this error is an incorrect order of boot devices in BIOS. Or the HARD disk is damaged. A hard drive may become inaccessible due to read/write errors, failures or damage of virus attacks. What I can suggest is for you to follow the instructions given by Greg Carmack via this link.

    This should help get your query with «verifying DMI pool...» Disk boot failure"set.

    Let us know how it goes.

  • Problem with "Extended desktop", integrated display is disabled

    Hi all

    I have a MacBook Pro 13 inch early 2011 with OSX El Capitan 10.11.4.

    Just before I upgraded to 10.11.4, I use to work with "extended desktop" using the built-in screen and the external monitor. Since the update, whenever I connect the external display it goes automatically to the external screen and completely disables the built-in screen. Sometimes removing the HDMI cable (with mini port adapter), putting the MacBook to sleep, log in again and the Mac, the awakening back on two screens, but most of the time he spends just go back to the external display only. This gets really annoying.

    When you use the external monitor display poster preferences only options of this monitor and my arrangement tab is missing (like the built-in display is temporarily disabled). By clicking on "Detect displays" (after pressing option to show) doesn't change anything. Using the brightness to toggle keys mirroring does not work either.

    Is - it there anyway that I can configure so worth by default "Extended desktop" with built-in monitor on and external display?

    Any help will be appreciated.

    Thank you

    Hi there Ajgalvezm,

    It seems that your computer does not work with your monitor external because you upgrade 10.11.4. I would use these steps in the following article to help you solve problems that:

    Get help with graphical problems on external displays connected to your Mac.

    Restart your Mac in safe mode to reset the default display resolution.

    If booting safe mode doesn't resolve the problem, reset your Mac NVRAM and SMC to reset the video ports on your Mac to their default values.

    Thank you for using communities of Apple Support.

  • Issues with Dell desktop computer wireless and D-Link wireless network card. Only able to get wireless access by checking "Use Windows to configure my wireless network". This kind of file sharing impossible.

    original title: can't see the computer on wireless internet!

    I hope that's not too much detail, but I would like that the sequence of events to be clear...

    I have a Dell desktop computer that's probably six or seven years now.  It did not come with a wireless card, so I bought a DLink router and combo card wireless, install both with the DLink software.  It works beautifully.

    Later, we through my rep AT & T DSL, I got a Motorola modem/router with wireless capabilities.  I had plugged directly on my computer Dell desktop and moved to a Dell laptop DLink wireless receiver.  No problems.

    The Dell laptop is dead and the DLink receiver has not been used for a long time.  Family of my daughter moved to our place, and I have connected his desktop computers and laptop to wireless internet, using the Windows Connection Wizard.  Still no problem.

    I got a new ASUS laptop, I also linked using the Windows Wizard.  STILL no problem.

    Now, here's the problem comes.  I moved the Dell desktop computer, connected the DLink wireless receiver to it and I am able to get wireless access ONLY when I go into the properties of PC, click the wireless networks tab and check the "use Windows to configure my wireless network" box.  Then I can connect correctly, but I don't see this computer on my wireless network.  Bad luck... because I want to be able to access share files.  When I try to connect using different assistants of Windows, I get a message to the effect that, if I used another software to connect to the program, I can't use the Windows Wizard.

    So, what can I do to remove the original configuration of DLink completely and to connect to my wireless network using the wizards in Windows?  I uninstalled the software of DLink, but it seems to have no effect at all.

    BTW, Dell desktop computer is running XP, office computer of my daughter is running VISTA, and two laptops are equipped with Windows 7.  I can see all the computers on the network with the exception of the original Dell desktop computer wireless.

    Any help would be appreciated!

  • Windows 7-problems with the laptop computer's System32 folder

    I bought this brand new Acer Aspire 5251-1005 computer laptop a week ago from Best Buy and it comes pre-installed with Windows 7. Everything went beautifully except for an unknown problem. A guy organized, I have some of my important programs pinned on my taskbar (for example, MSN, office, Skype etc.). However, when I right click in a program (ie. MSN) and click on a task (IE. Mail box), this task is not activate Instead, my System32 folder opens... Very weird.

    I searched on several forums. I tried to do a system restore (quite a pain to reinstall everything) and did not work. Tried to activate my guest account to check if my account is corrupted. This was not the case.

  • Problem with the Desktop version, Tablet and phone. Help, please.

    I created a website in Muse. I created the Desktop version, Tablet and phone. But my problem is that, once I open my website on my tablet or phone it shows not always the correct form. Most of the time it's to show the offline version even if I am looking on my phone. What can I do?

    Hello

    I watched address phone and noticed 2 flaws.

    1 URL internationalchangepartners.com no redirects to internationalchangepartners.com/phone when I tried on the phone.

    Please do the following to solve this problem

    Hello, I made a site using the 3 platforms: desktop, Tablet and smartphone, but... on tablets and smartphones appears the design office, no idea why?

    2. now when I check link internationalchangepartners.com/phone I saw that the Menu options are linked with pages of the tablet.

    To over come this I suggest you to select hyperlinks with a lot of attention. Once you select the Menu item and add the hyperlink, select the option under the phone if you are available for the phone.

    Hyperlink has a separate list of the link for each structure. Look at the screenshot below.

    Once there 2 flaws were fixed there is no problem with the site.

  • Sharing a wireless connection on a laptop with a desktop computer

    Someone just mention something about the possibility to share wireless being removed in Windows Vista and 7, or at least the 'home' versions Is this true?

    I wouldn't be able to use a laptop running Vista Home Premium to connect to a Wi - Fi hotspot and then to share that connection with your desktop via a crossover cable by using ICS? I know it's possible with XP Pro very easily.

    In Vista, you can use ICS.

  • An AMD Radeon 6970 graphics card will be compatible with my desktop computer?

    I own a HP Pavilion HPE h8xt series desktop computer.

    -INtel Core i7-2600 processor

    -16 GB of ddr3 RAM memory

    -460W power supply

    From now on, I have an AMD Radeon 6850 in my office, but I want to know that if I buy a 6970, if it will be compatible in my office and if not will work properly. Or if he simply does not work.

    Please answer as soon as possible because I need to know whether or not it is necessary to collect money for her for Christmas!

    Thank you!

    Hello

    Make sure that this AMD Sapphire 6970 will adjust.  It is 9.8 "length.  I also checked the length on the Sapphire site.  It's a card double slot.  This map requires a PCI-E power connector 8 pins.

    The Corsair CX600 is sufficient for the video card above.

    You can review the performance comparison between the 6850 and 6970 to this site.  Notice the power for the use of 6970 which means more heat inside your PC.
