Windows 7: Win7/Vista Intel Mobile 4 Distortion/Pixelation Issues

26 Jan 2010   #11

Windows 7

" Sooo for those of you who have this problem disable your hardware virtualization bios options to make the issue go away"

as a non-techie, how can I do this.. having exact same issue after upgrading from Vista on my Dell 1737..

actually just checked via a MS tool and it says I do not have hardware -assisted virtualisation .. any ideas ?

windows 7 home premium, opensuse 11

I hope that your PC is it okay now.

I want to tell, that my story is the same.

HP dm1, SU2300 CPU with enabled virtualization, win 7, areo, and the distortion like in the error.jpg in the opening post.

How works the XP mode under Win 7 with aero? This problem seems to be lot more commonly than we previously thought.

Windows 7 Ultimate x64

Identical issues on Lenovo R400 on Win 7 Ultimate X 64 running the very latest (@ July 2011) drivers from Lenovo, Intel as well as Windows 7 Update. The issue is best seen on this laptop by putting the laptop to "sleep" with open graphics windows (e.g. Spider Solitaire). Pixelation is evident upon "wake up". This issue has not been experienced upon fresh boot on this laptop, almost always after "waking up" the laptop as I tend to regularly suspend the laptop during normal use.

The very excellent suggestion on this forum, to disable both virtualization options in the BIOS, also resolves the pixelation issue on the Lenovo R400.

win 7 64 ultimate

I found only one virtualization option on my hp 2740p tablet pc -- and it was already disabled... yet this pixelation issue remains -- is this hardware or OS issue, do you guys think? thanks!

Triple Booting with Windows 7 Proffessional SP1 64 bit, PCBSD9.1 Isotope 64 bit and ArchLinux 64 bit

Sooo off I went into the BIOS while on hold to disable these options. I then booted into Windows, let it install the latest video drivers from MS Update, and I then rebooted and tried to reproduce the problem with Aero enabled... and guess what??? I could not reproduce it anymore! I have the laptop back in the hands of the user now and so far for the past hour or so it has not happened again. Sooo for those of you who have this problem disable your hardware virtualization bios options to make the issue go away. I had already upgraded from A01 to A17 bios a few days ago as well but that didn't help, so it's not something that was fixed by a newer bios.

When the tech returned from having me on hold he canceled the motherboard replacement and so far so good, no issues once the virtualization options were turned off... yay!
Sorry to jump into this thread... i was facing similar probs since long and i used to log out and log in to set right the distortion (refresh didnt help)

can you explain on where you got the option to disable virtualization ?
my hardware spec :
T 500 Laptop, Core 2 Duo P8400 2.26 Ghz processor, GB DDR3 ram, Intel Series 4 Chipset. Display Resolution : 1280 x 800
I am running Windows 7 Professional 64 bits SP 1. Just for info, i do not have any such problems on the other 2 OS i am using... i even uninstalled the display driver and rebooted so that windows searches for new driver and installs.. still same

I would really like to get over this problem...

Triple Booting with Windows 7 Proffessional SP1 64 bit, PCBSD9.1 Isotope 64 bit and ArchLinux 64 bit

As an update... i have now disabled the virtualization from BIOS and then activated aero themes...
unfortunately, the pixelation seems to persist (even after i updated the driver from intel)
one consolation is that the pixelation clears when i hover the mouse over the area... !

i am sure this may not be purely hardware related problem cos for the same laptop and the other 2 OS i use i do not find any such errors... hope this issue will be resolved !

Triple Booting with Windows 7 Proffessional SP1 64 bit, PCBSD9.1 Isotope 64 bit and ArchLinux 64 bit
seems to be much better now..

as an update to my previous post... i followed this change
after disabling the virtualization from bios, i booted to win7 and re-installed the driver....
this time with a change... i unchecked the check box that said re-run windows and activate for aero themes or something like that... the system asked for a reboot and now the distortion seems to have gone... i am almost 15 minutes after booting and the display is stable !

all my previous attempts i noticed that till i went for rebbot, distortion was not there and after reboot i was back to square one ! this behaviour prompted me to uncheck the box and then go for re-install of the driver which seems to have solved the issue....

thanks to all of you guys who have helped me in identifying this problem....
