Problems with HP laptop (model dv4-1225dx), turns off

I have bolded the important bits.

To be honest, I had problems with this computer since the beginning.  A lot of it, however, is due to a problem of overheating resulting from a wrong place fan and cons set to automatically install updates.

But a cooling pad and a setting to choose what is installed more or less solved that.

Now for the problem.  I installed Windows 7 a few months ago, and everything has been working fine since then.  Since yesterday, however, the computer shuts down after a few minutes of being on.  Now, the fan on this thing is very strong, even in low use (another drawback of this model, but is not the point) so I'm pretty sure that's not working.  But it does not seem likely that the computer could warm up enough to warrant a hard stop in a few minutes, it?

I tried the Startup Repair but the computer is turned off before being able to complete it.  I'm still able to do if I start Windows normally, but once again only for a few minutes before it stops.

So I have two questions:

1. replacement of the fan of something I can do myself, or is it too integrated or complicated to manage?

2. the random stop is really a matter of fan at all?

On an unrelated note, Norton seems to have dug his own player to backup on my D drive, which means it cannot do a good backup.  How can I get rid of what I properly backup?

Hello

It may be a faulty hard drive. Try to run a test drive. here

It can also be a fan problem. You can replace the fan yourself. Step by step here Guide

With respect to the reverse, use the one that provide windows. Try this from microsoft. here

  • 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.

    If anyone has a solution (hopefully one that doesn't require too many steps) Please help me!

    I had the same problem with ACER 5251-1513, and it turns out to be a third trial that Shredder calledEgis Tec included with MyWinlocker suite program.

    After you have uninstalled Egis Tec Shredder, the system is returned to normal.

  • I have a problem with my laptop does not connect to the internet. It connects to our wireless very well, but it doesn't have an internet connection.

    I have a problem with my laptop does not connect to the internet. It connects to our wireless very well, but it doesn't have an internet connection. It connects to other networks wifi very well with Internet access, is that the wireless in my house what it connects to. When I diagnose the problem, it says "Cannot communicate with DNS server (208.67.222.222)", and then under that it says: "languished network diagnostics remote hosts, but had not received a response." It connects to the Internet through an ethernet cable, but it is rather annoying pulling the cable autour. I currently have Windows Vista Home Premium. Thank you!

    Now, you may need to contact the support of Panda Internet Security centre to change the settings so that wireless is enabled through it.

  • HP Pavilion 17 Laptop: Wireless capability is turned off

    I bought the new laptop and has worked well for me the last couple days. Clicked on another page and says unable to connect to the Internet. Resolve to see what the problem is and says 'wireless capability is turned off. Tells me to find keys function or button wifi, but as far as I know I am not one of them. I checked my wireless networks and they are supposed to connect automatically, so turn on the wifi on the laptop seems to be the only problem, but it seems that I can't. How do I turn it back on?

    I had no idea f12 was the wireless icon, who held it down and worked, thank you.

  • Problem with the laptop overheats.

    Hi all

    I am working on a DELL laptop. He even sends warm air by her orifices. I think that probably there are some (or large amount of) dust on hardware devices inside.
    I know that the best way is to open it and clean these parts by a compressor (for example), but there are two points here:
    1-do you agree that this hot air is due to dust and I need to solve this problem by the shears of cleaning equipment?
    2. I did not open any computer laptop ever, a little scared (because this laptop is not mine). You always tell me to do? If so, what are the rules I have to observe before, when and after you open the laptop?

    Thank you.

    You can sometimes get the lint and dirt outside blowing into the cooling in the other direction with the laptop turned off but it must be a blow hard. The short pulses with a can of airduster spray is more effective.

    Unfortunately, if it's really boilerplate it may not work and the fan removed to erase it. It's the ease varies depending on the model. There are many videos of portable Louise on utube certainly of a different quality. Unless you are 100% sure they can be a bit complicated because there are a of clips often hidden to save any screws holding together

  • I have a problem with my laptop system restore and I can't open it

    Original title: Please help me

    Dear friends
    I have a problem of my laptop whit system restore and I can't open it.
    A few days ago, my windows xp reboot both and colud not restart my computer. I had to use my back for recovery system because the other option as in mode without failure or last good configuration didn't ' work corectly.
    This event occure to me several times and I am very confusede on this subject. . I have latest version of avast anti virus in my laptop. Please guide me and give me your solution for my problem towing?
     
    Thank you for your kidness

    What happens and what do you see when you try to open the system restore?

    When you say things "did not work", we need to know which "did not work" means exactly... I get an error message, nothing seems to happen, the system crashes, etc.

    Try answering the following questions, the better you can:

    Maybe someday the dialog box 'ask a question' forums XP will ask these questions automatically when a new thread is started so I don't have to ask every time.  It might even be possible to solve a problem in a single response when enough information is provided.

    Please provide additional information on your system:

    What is your system brand and model?

    What is your Version of XP and the Service Pack?

    The afflicted system has a CD/DVD drive work?

    You have a true bootable XP installation CD (it is not the same as any recovery CD provided with your system)?

    What you see you don't think you need to see?

    What do not you think that you should see?

    If the system works, what do you think might have changed since the last time it did not work properly?

  • Problems with HP laptop Pavilion dv7-5004tx with the sound and video is this laptop being recalled?

    Hello I desperately need help.

    I have a laptop HP Pavilion dv7-5004tx, which is about a month.

    It's a really highy specced machine, 8 GB mem 1 GB card video etc.

    The problem is that when it video or audio playe he stutter along. I sent to hp about this problem and they do not come back to me? It is currently running windows 7 64 bit home edition.

    The model number does not exist when I search the site of HP?

    I noticed on some laptop computer review sites that it was be recalled, but it was the only information I could get. No specefics.

    I would really appreciate help from anyone out there? It seems as if HP tries to hidden it? There is no information about this laptop on any one of these sites (that I could find) and model number doesent exist on their site either.

    I think I have found a solution to my stuttering audio and video playback. I disabled the HP 3d drivegaurd software and so far it seems fine. After a search in any of the HP forums support I discovered a number of people have had similar problems with various portable computers HP.

    The solution seems to be to disable the car care software? HP aware of this and they do nothing to solve the problems with the drivegaurd software?

  • Audio problems with Toshiba laptop

    So I have a Toshiba laptop with Windows 8, and the noise on this subject with headphones is way way too low, that he was stronger on my old laptop, the speaker volume is strong so I don't understand why headphones are so quiet that I uninstalled the drivers that came with him and got the generic Microsoft High Definition Audio ones , but that did not help either, I made sure all sound bars are completely upward in the settings of the headset and I ensured that no effects were on and that the quality was 24 - bit, it of just the laptop or is there a problem with the driver? is it possible to simply drive the sound from the speakers in the headphone, or is it necessary that when I plug in my headphones must change the one that says earphones. Help? Basically, it seems that the midrange and treble are too low, while the bass is stronger, it sucks.

  • Problems with my laptop and my HP C7280 All in One Printer

    I have a network problem which gives me fits. I have a HP Wireless HP C7280 All in One Printer in one of my rooms where my desktop computer. My son and I have all two laptops that we have been able to use wireless network mode to print on the 7280. One day that my laptop (HP dv5-1002nr) even though it shows I am connected to the IP address of the printer, no longer cause the 7280 printing. All parameters show that I am connected, but when I print and go to device settings it shows the document is waiting and then print, but nothing prints from the printer itself.

    I checked all the network settings, reset everything again, downloaded the latest drivers and all without success. Today, my son has had 2 other laptops and was able to print wireless to the 7280 and it was also able to print wireless from the desktop in the same room as the printer, so we know that the issue is not with the printer. Some of these laptops are also HPs.

    At first I thought that maybe there was a problem with my LAN driver but check that and everything appears to be functional and up-to-date. What is strange, is that I can email this cell phone to my modem wireless of course work in this regard. However, no matter what we did to make sure that all our drivers and settings are correct, we are still unable to make the printer print.

    Anyone have any ideas because we are totally frustrated.

    If it looks like your question:

    After you install the product on a network, you turn off the computer, and then, and the product loses functionality. The product is no longer prints and disappears from the icon of the product in the menu devices and printers in Windows 7 (64-bit).

  • Problem with my laptop battery life

    Hey owners of Toshiba! Is anyone having problems with their battery life? My laptop does not work as long as it should! Or so it seems. Any ideas what could be the problem? What is the machine?

    Try to let the battery discharge completely before recharging it. When you decide to use the power of the battery, remove the power adapter when the battery is fully charged and running on battery power until this that completely discharged and not only for 10 minutes, for example
