Computer screen flicker laptop, recoveries, BSOD

We have two HP Pavilion dv6t-3100 CTO Select Edition Entertainment laptop bought at the same time. The screen on one of them was flickering, had to make a few recoveries and has generated at least a BSOD.

Curiously, Intel driver problem child is 8.17.0010.0029, and the AMD driver is 8.741.1.1000, date dated 22/06/2010.

But the laptop without problem a driver Intel 8.17.0010.1043 and driver AMD 8.771.1.0, dated 08/09/2010.

Huh? The only difference between the two is that the 'bad' laptop has an i7-720QM ICU while the "good" laptop has the slightly more powerful i7-740QM. So why the pilots different?

In any case, a solution or ideas appreciated.

Hello @NoSco ,

Welcome to the HP Forums!

I understand that the screen flashes on your computer laptop dv6t.

In view that these laptops use different CPU (and thus a different Intel GPU) they will use different driver version. Intel / AMD switchable graphics driver contains a modded version of the AMD Catalyst Control Center which must be configured to support on each Intel / AMD combination. This explains why they have different versions of the driver.

The flashing display can be a few different things. It could be the inverter, the screen itself, the motherboard or the GPU.

The simplest test to refine things is to test the laptop with an external display. This will immediately identify the issue as a problem of material with the display or the inverter.

If an external display has the same issue, it would mean the issue lies within the operating system or the GPU.

To test further, you can try to load the system with F10 BIOS and see if the problem persists there. Who will reign over drivers because they are not used to run the display in the BIOS and initialized only when Windows is loaded.

If please test each one and let me know the results.

-Edited grammar.

  • Laptop computer screen flickering Lenovo G530

    I have a laptop Lenovo G530, who has a problem with the flickering of screen that worsen. The computer screen start through a crazy screen flicker then stop and try again. I already checked the cable connection to lcd screen, motherboard and reinstall connection of the LCD to motherboard located under the keyboard, as someone suggested in another ad that I found online that solved the problem for them. I'm starting to think that there might be a bad converter or screen because I hooked laptop for external monitor and it works well with flicker happening when the flickering occurs on laptop.

Can I just attach an adapter at the end of the wall to the monitor cord to fit Italian DC connector configuration or do I need a converter between the end of the US AC 3 earth-pin male connector and the Italian DC Jack?

  • Computer DV7-1825dx laptop screen turns off at least connected to the HDMI

    I have a Pavilion dv7-1825dx running Windows Vista Home Premium 64-bit.  The other day, I simply closed the laptop into hibernation.  At the time, it was only connected to a printer and a wireless mouse.  The next day, I opened the laptop and it turned on but the screen stays off.  I shut down the computer by holding the power button and then turned back on.  The screen appeared and asked me if I wanted to start Windows normally.  Then, I got the loading screen for Windows.  As soon as he was done loading, the screen turns off and the chime sounded for the login screen.  I repeated again than having the same problem.  I typed my password, but the screen stays off.  Because I often hang my computer to our TV via HDMI, I thought I would try it, and that is, both screens lit.  I then disconnected the HDMI cable and the computer screen exploded again.  Plugged into the HDMI and activated.  I went into options for NVIDIA and noticed that there is an analog display with the screen of television and laptop (up to three screens on the list).  I restarted in safe mode, and the screen of the laptop works great.

    Any ideas on how to solve this problem?  That I can not connect my laptop to the TV whenever I want to use.

    Thank you advance!

    Save the driver on the desktop and install it from there, not in a temporary folder.

    Create a Windows restore point before starting.

    During the installation of the new driver, click on "Custom" and there will be a link to uninstall the old drivers and all of your current settings, this before you install the new driver.

  • Black laptop computer screen discoloration

    Hello! I'm here because I had a problem with my laptop recently. I have a HP Pavilion G6 (don't know what year but I bought it in 2012) and for about 2 weeks, my computer screen has just been randomly fades to black.

    It is not closed, it stays on and I can still here sound, but the screen remains black. I tried to use an external monitor, but it did the same thing. Also, I get no error message like this happens.

    I ran malwarebytes and AVG, removing all he detected, but the same thing is happening. I don't know what is happening.

    I did not open my computer or anything like that. Just in case, he began to arrive.

    I hope that someone can provide an answer, it would be greatly appreciated.

    I suggest you try to do the following:

    Press Windows key + R-> type regedit-> press ENTER. Click Yes, if UAC prompts.

    See the link to back up the registry first, before continuing:

    http://support.Microsoft.com/kb/322756

    Now, in the left pane, navigate to the following folder:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control

    Once you select the control, you will find a set of entries in the right pane.

    Double-click "WaitToKillServiceTimeOut" to change the value. Change it in 2000.

    Click Ok, close the registry editor and restart the PC to check.

    If the problem persists, try this:

    Click Start-> type cmd-> press Ctrl + Shift + Enter (to start cmd in administrative mode). Type the following command and press enter (make sure all your files are saved and all applications are closed):

    shutdown-s-t 00-f

    This stops the PC. Check the time it takes to turn it off. If the problem does not occur, change the value in the previous method in 1000 and check. If the problem persists, change 500 then check.

    If the problem occurs, it may be due to drivers. Try to update the drivers, specific display drivers. If no update is available, try to reinstall the drivers: uninstall the drivers, reboot the PC, install the drivers, reboot the PC and then check.

  • G580 screen flicker to black and heavy pixelation

    So I have a laptop G580 which is in good condition and recently updated.

    About a week and a half, I noticed that my screen flicker and would become very pixelated with color and sparkle black (I've included a photo). Usually, he would go back to normal, but occasionally, he would continue to flicker and pixelation. Move the screen does ' t affect the problem, restart sometimes helps, and I did scans of material that came back clean. (Programmes of work like nothing is wrong, it's just the screen) Nothing in my laptop seems to be brocken so I don't know what is happening.

    Please help because it seems to be happenong more often!

    That's what the screen would look like:

    If you can find a good shop 'good reputation' that offers you a free diagnosis, that may be your best option. Usually, it's a simple solution, if it is the LCD cable. If it is the graphics card, it's more expensive, but less than the cost of a new laptop.

    You can contact Lenovo directly to inquire about the warranty and if it will cover your current number before you pull the trigger on the repair.

    Good luck.

  • Yoga 2 Pro big screen flicker followed in black

    Hello

    Does anyone else get this problem? I don't think it's the same screen flicker that is experienced by a few others because of problems of auto brightness...

    It flashes black and then all cela turns is not responding after awhile... and although the video shows what is happening in a low light environment, I had this encounter for a beautifully lit place as well...

    Any thoughts?

    I've posted a copy of what is really going on google reader.

    Is this a case of problems of motherboard? I just got my laptop about 3 weeks ago.

    No chance for an exchange of 1-1?

    Can we go to the Intel Graphics Control Panel, press power button and then go to "on battery" tab. 'Panel auto refresh' option is enabled? If it is then disable it. This option makes the Board consumes less power, gives better battery life, but there the exact symptoms every now and then.

    If you have installed Yoga graphic driver actions then download the most recent Intel, install it and turn this option off.

    To install the new driver, you have to uninstall the old, otherwise it will not allow you to install a new. To uninstall it go to Device Manager, display the properties of the driver, uninstall button driver.

    If this does not work then I don't know, is probably a hardware problem better trying to get a replacement.

  • Officejet 6310 all-in-One: can't send faxes from the computer screen

    We use an Officejet 6310 all-in-one printer. Computer of my wife, a laptop Toshiba Satellite Windows 7 Professional, has suddenly come to the point that it will no longer send faxes from the computer screen. We get an error message that something must be installed or reinstalled. We have lost the CD of the software provided with the printer. We can send a fax if we have a document printed to power the machine, and we can print faxes. We lose a lot of paper and ink because of this problem. Help, please.

    Hi GregsterMc,

    Given that the Fax icon is not displayed in the window of printers and devices, you need to uninstall and reinstall the software again. This should solve the problem.

    Thank you.

  • computer screen pink

    Hello

    my computer screen is pink and not on purpose. I think that my screen is going bad or something because I can still do stuff on my computer, but the screen is pink and I think that the display degrades because there rose is no longer only slowly turns in neon colors or something. I need help fixing it. If I can't fix here at home where I take it? best buy? Or who should I call?

    Hello

    These symptoms suggest corruption graphics driver or lack of graphic material.

    Go to the website of the manufacturer of the graphics card or your computer > Search a drivers and download article > search your computer or your graphics card model number > your operating system > drivers for it: either video / graphic / Chipset (according to the wording it) > download and install the drivers.

    If that fixed it, it seems to me be a problem of graphic material.

    If a desktop computer, or share your graphics card with a good.

    Or, if graphics card built-in, you will need to install a graphics card in a slot of the motherboard to see if this solves the problem.

    When a laptop; If under warranty, contact the manufacturer.

    If it is not under warranty, contact a good repair shop, local and good REPUTATION.

    See you soon.
