HP Desktop fan accelerates for no apparent reason

Salvation of the elbow,

Try this procedure:

Disconnect the PC and open it. Clean all the dust. Carefully, remove and replace all the cables towards the mother board one at a time. Do the same for memory DIMM and the video and the sound of cards if you have a.  You can buy a can of compressed air to blow the dust out of the heatsink from the CPU.  Plug your PC back in and give it a go.

If your PC is not current running bios level 5.22 try then upgrade to the latest bios level.  If you are already running 5.22 then try clear the CMOS.

You can try removing the heat sink aluminum end shown in the picture of the motherboard (lower right corner), remove the old thermal paste with little of isopropyl alcohol and then apply a thermal paste Artic Silver 5 and reattach the heat sink.

    Could you try disabling graphics hardware acceleration to Firefox? Due to the recent driver updates, many users know strange stability and performance problems related to this function.

    You need to restart Firefox for it to take effect, so save any work first (e.g. you compose mail, documents online that you are editing, etc.).

    Orange Firefox button or classic menu Tools > Options > advanced

    In the mini ' General' tab, uncheck the box for "use hardware acceleration when available.

    If you restart Firefox, the issue is resolved or at least improved?

  • Satellite 1900-303 turns off for no apparent reason

    I got my Satellite 1900 303 for about 2 years and no problem. In the last month, I had a problem with him turn off his car suddenly and for no apparent reason. I checked virus and have found no virus. Can anyone suggest why I did this. I was wondering is that he has been making overheated?

    Thank you

    Hello

    Believe me, there is always a reason why this happens. From your description, I assume that your unit is overheating. If the temperature is too high the unit simply stops.

    You need to clean the device. After that cleaning the unit should work properly again.

    It is almost always a hardware problem, not a a Windows. Both
    the most likely causes are overheating and power problems.

    Hello

    I use a laptop Windows 7 in the office wireless remote for my desktop running Vista. The regular connection disconnects after a few minutes, then displays the window pop-up "try to reconnect 1 20. It always with success reconnects itself during this first attempt. During the time when the connection is lost, the internet connection is fine, in other words, I could use my cell phone to browse the internet.
    Any ideas what could be causing this?

  • How can I fix the "drag and drop" feature in Windows 7? It used to work, but now does not work, for no apparent reason!

    How can I fix the "drag and drop" feature in Windows 7?  It used to work, but now does not work, for no apparent reason!

    What happens when you try?  Make sure you drag the icon image and not the text of the name.

    If it still doesn't work there are some registry changes that can try to alleviate the problem.  But because the changes to the registry are tedious and dangerous, I recommend to leave the system to repair it for you.  Here's how:
    1. Type of restore in the search box of the start menu to find and open to restore system files and settings from a restore point.
    2. Click Next, choose a date before the problem started, then click Next once more.
    • This process only takes around 2 minutes and only restores your system files/settings: it will not affect any of your files, documents, photos, emails, or anything else.
    If the system restore does not resolve the problem try this to replace missing or corrupted system files.  Here's how:
    1. Type cmd into the start menu search box, and then press Ctrl-Shift-Enter to launch as administrator.
    2. At the command prompt to start the File System Check, type sfc/scannow .

  • Office Add-in for Office 2016

    Office 365 has just updated all my applications to versions of 2016.  Office Add-in for PDF (PDFMOfficeAddin.dll) doesn't seem to work in this version.  It seems also selected and active in the Office applications, but the Add-in does not work.  I rely on this add-on all days - ideas on how to make it work again?

    Hello

    I guess you have to connect with Microsoft technical support to function as Office 2016 Add ins are not yet compatible and would not work with Acrobat DC as it was recently released.

    Microsoft help you revert to the previous version.

  • My video production accelerates for no apparent reason

    I use adobe first pro 2.0 and I'm having a lot of trouble with the final results of the video, I tried to change. It's a simple edit that I crazy on video, I didn't was crop the video original and added a watermark that everything worked well, the problem is that the final video output accelerates the length upward of as 2 x the speed of the original video, that I have edited...

    The duration of the video is exactly the same as the original duration, the only thing that changes is the flow rate of the video, but the AUDIO speed is exactly the same as in the original video. This means that the video gets horribly synchronized with audio because the video is 2 x the speed of audio.

    I see no reason why its doing this, I even changed the FPS several times when exporting it. Ive exported several times with several different parameters, including changes in bit rate and sound still give me the same problem.

    I have no idea how to fix this and spent hours trying to search online, google and looking for a solution and not youtube videos could not. forums so is my last stop before I pass video editors altogether. can someone help me with this please? Its incredibly frustrating to spend so much time solving a simple culture error and paste video editing...

    Download MediaInfo and check your media to find out if there is a variable rate (see the "tree".  If it is you will need to convert to constant pace for first.

  • For the last week or three Firefox updated two or three times for each update and sometimes for no apparent reason...

    For the last week or three Firefox updates two or three times for each update. Sometimes it refreshes without obvious reason. For example, I'll be in the middle of typing in the message forum block & it refreshes. Or by filling out an online form. Or simply viewing a page.

    You can check for problems caused by an extension that is not working properly.

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance).

  • Satellite M50 breaks down just for no apparent reason...

    Well, I had this problem a few months after I got the laptop. It would be just closed especially if I had it on my bed, now I keep it on top of a desk and it's better but lately its been going again. Please help I don't know what the problem is.

    I imagine that the laptop when it is placed on the bed cannot be cooled properly and if the material critical temperature is reached the laptop, turn off without any warning. The material will be protected on this path.

    On the desktop, it works better because the cooling fan is free and the cooling fan is not blocked. If you use your laptop on different places, it is possible that there are now more than inside and portable dust should be cleaned. Believe me the dust can disturb the cooling and the laptop turns off again. Especially by games or applications that requires the CPU and graphics card to run at high speeds.

    Think about it. You can try to clean the cell phone only or it can be done on the professional manner of service.

  • Qosmio G20 wakes up after hibernation for no apparent reason

    Hello all,.

    For a while now, I've noticed that my Qosmio G20 tends to wake up from hibernation at random times for no reason apparent. When I place it in hibernation during the night, it passes in a State of hibernation, but (normally) after a few hours suddenly waking up from that State for no reason.

    Obviously this isn't a big issue, but I prefer to Hibernate when it's possible (as opposed to the day before) and it's pretty boring to woke up at 04:00 by triumphing over the Qosmio music shine (it's still better than windows ' your da!) " : P)

    Any ideas?

    Kinder,.

    Hi Lee

    Please check the BIOS settings. I'm not 100% sure, but on a page on the side right, there must be some sort of wake-up option. Check if this option is enabled.

  • Satellite Pro A210-1AZ - I lose the WIFI connection for no apparent reason

    I am connected to a wireless network with my A210-1AZ. There are 4 wireless networks in my area, belonging to other people on my street. I connect to my network, and everything seems to work fine...

    Up to an hour, I just lost the connection without apparent reason. I click on the ' Connect or disconnect ", and he cannot find + all + 4 wireless networks. I press refresh - nothing. I go to Device Manager, disable then re-enable the best to the wireless network device. Can I do "connect or disconnect", and it shows all 4 networks back. If I connect... for another hour... then I have to do it again.

    It seems worse when I use the network a lot, that is to say. Download large files, sometimes after 10 minutes. If it is fairly inactive, it lasts not more. But it always happens in an hour or two.

    It becomes really annoying!

    Please do BIOS update to the latest version. The problem should be solved.
    By the way: card WLAN that is listed in the Device Manager? Intel or Atheros?
