PC freezes suddenly and white screen appears especially when 4-6 web pages are open

Hi all, I have a dell inspiron 640 m that ran XP. A few months ago, I upgraded to W7. Since the pc then freezes and white screen will appear suddenly especially when web pages 4 to 6 are open. PC is frozen is anything other than a white screen. He will not answer. only way out of the State's pressure on the power button to force quit or restart the pc. This happens without warning and is really annoying. has not yet found all the answers to this question. all proposals/solutions are gladly welcome and appreciated. Thanks in advance.

32-bit W7 and SP1 installed.
Intel T5500 @ 1.67 GHz RAM 1 GB disk, 100 GB with recovery 10 GB disk, ram taken in charge with 4 gb SD card.

Hello

Since you upgraded to Windows 7 have you run Upgrade Advisor and check compatibility
Center (for compatibility of the device)?

Windows 7 Upgrade Advisor <-- please="" run="" this=""> http://www.microsoft.com/windows/windows-7/get/upgrade-advisor.aspx

Also check the Compatibility Center (for the compatibility of the device)?
http://www.Microsoft.com/Windows/compatibility/Windows-7/en-us/default.aspx

Check with the system and peripheral manufacturers for updated drivers and many have special instructions
to help the upgrade to Windows 7. Check for updated BIOS, chipset of low-level drivers and ask for the
Reference Dell Forums where there will be others with your model who have upgraded.

This troubleshooting is a waste of time, if the system is not compatible Windows 7
or there are Windows 7 BIOS and driver updates that have not been implemented.

------------------------------------------

Several troubleshooting methods:

What antivirus/antispyware/security products do you have on the machine? Be one you have
EVER had on this machine, including those you have uninstalled (they leave leftovers behind which)
may cause strange problems).

If no joy there's something blocking perhaps.

Start - All Programs - Accessories - System Tools - IE with no Addons - what works best?

IE - Tools - Internet Options - Advanced - tab click on restore, and then click Reset - apply / OK

IE - Tools - Internet Options - Security tab - click on reset all default areas - apply / OK

Close and restart IE or IE with no addons

not better?

IE - tools - manage Addons (for sure disable SSV2 if she's here, it is no longer necessary but Java
installs and it causes more questions - have you never update Java to go back in and turn it off again.) Search
other possible problems.

Windows Defender - tools - software explore - look for problems with programs that do not look
right. Allowed are usually OK and "unauthorized" are not always bad. If doubt about a program
ask about it here.

Could not be a free - SpyBHOremover - BHO - standalone program, needs no installation, download.
unzip and run - all are not bad, but some can cause your question (toolbars are BHO).

  • Mozilla web pages are white with text black\blue &amp; netflix does not work Win10

    Use Firefox to work fine but now it isn't (currently version 39)
    At first I noticed that netflix produced an error when I tried to start the playback of a video, but after I uninstall firefox and remove all profiles she won't even let me visit the web page by giving this error

    The secure connection failed
    An error occurred during a connection to http://www.Netflix.com/. The peer certificate has an invalid signature. (Error code: sec_error_bad_signature)
    The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

    The other problem I've noticed is that some web pages are not correctly such as Mozilla forums is just a white text background blue and white

    I tried every evening 64-bit laptop same problem
    Crome\Explorer work well

    Thank you

    The difference between Firefox and IE/Chrome, is that IE/Chrome share the Windows certificate store. Firefox has its own certificate store. (That you have deleted by removing your profile.)

    This error can be caused by a series of questions, but generally, certificates are generated by an intermediary such as a proxy server, your security or malware software. We look at who it is.

    Q: do you use Avast, ESET, Kaspersky or BitDefender, or browse through a proxy?

    If you have sites where you have created a security exception, like this site, check the certificate for more information on its transmitter. You can click on the padlock (or grey warning triangle) in the address bar, and then more than information, and then display the certificate. The areas to check are "issued by" and "hierarchy of certificates. I've attached a screenshot of this site as an example of screen. If you can't view it in Firefox, you can use Chrome. I have attached this example, too.

    What do you see?

    Note: Firefox for Windows 10 support will be more complete version 40 which, if you're an early adopt, you can try in beta. I do not recommend nightly. https://www.Mozilla.org/Firefox/beta

    Right click on an open area of the desktop and select Properties.
    Click the appearance tab.
    Click on 'effects' (in my Version of XP in German), perhaps you will need to click on Advanced.

    In my XP there is a "huge symbols" choice, if you have this choice, remove the hook.

    Good luck and have a nice day!

  • I downloaded the latest version of Firefox 13 and all Web pages are displayed wrong

    I downloaded the latest version of Firefox 13 after having quickly that I didn't have the latest version of Firefox. No Web page seems correct, including this one. All Web pages are displayed "plain." For example when I type in retail right now it takes a box or something to show me where to put space details - no box - only. I use Google as my home page. The Firefox logo was on the Google home page, but it is absent. When I go to Google Mail there is no checkboxes delete mail etc... when I go to the same pages using Internet Explorer pages display correctly if something's not on Firefox. I uninstalled and reinstalled Firefox without deleting my personal settings etc, but this made no difference. If my only option is to delete all my info I should do, but have been on Firefox and really don't want to lose this info. I checked all the settings when I looked not all Web pages display correctly in HELP and all settings are correct. What should I do? I don't want to go back to using IE, but that's basically what I have to do right now to the function to make banking operations etc...

    You are welcome

  • BlackBerry smartphone Email through Bridge suddenly stopped working - flashing black and white screen only

    Used email Bb bridge successfully for about a month since the purchase of the playbook. Then halfway through sending an e-mail response, the screen suddenly started flashing black and white. All bridge applications work perfectly, that e-mail is on BB Curve 9300.

    Tried all the solutions I can find it is similar on the forums, including delete 9300 battery, bridge etc., making the RST, re-installing but no solution.

    It was the main reason that I bought the playbook, so pretty useless.

    Any ideas how to behave?

    After trying all the options for similar problems listed in the forums without success, I finally found the security reset to factory settings PB sort the problem, at the expense of the loss of various data and downloads.

    Fortunately all relatively easy to recover from other sources, just in time.

    I hope this helps if someone else gets the same question.

  • Start-up and white screen issue after updating to v10.11.5?

    I can't say 100% that my problems are related to the last update, but I thought I'd ask.

    I've updated about 4 or 5 days ago, and although the questions did not begin immediately, they start after the update. It should be noted that I have never had issues like this before.

    Here are some of my questions on my MacBook Pro (17 inch, early 2011), 2.2 GHz Intel Core i7, 8 GB at 1333 MHz DDR3, Intel HD 3000 512 MB graphics card

    1. the monitor will sometimes go haywire and a strange split, screen where the mouse can go to the left side of the screen and reappear on the right side of the screen, because the office is now split into two

    2. computer crashes and the monitor starts flashing to show a blue zigzag striped background

    3 freeze during startup and never restart computer. Occasionally, it will start very well, but the computer locks upwards at some point while using

    4 computer at boot flashing out to a white screen then restart never

    Thanks for any help.

    Now I'm starting to think my problems are related to a single user, sign in. Only 2 people use the computer and my connection seems to be fine. No crashes or anything like that.

    The problems start when my wife logs in to his user account.

    Thought I would mention it.

    Any help/response would be appreciated.
