HELP! Windows 7 freezes

Hi guys...my first thread here and I really hope for some solution.

Here is the deal: I upgraded to Windows 7 Ultimate on my Vaio VGN-Z11VRN

Some of the drivers were used from the official site of vaio but from other model which has the same hardware and is eligible for free upgrade by sone (Z21). There are no errors in the device manager at the moment.

I use the laptop for work, on a domain...using a domain profile for this, but also at home using local profile but also the domain one.

At work it always freezes.... I mean at least twice per day. I've tried everything. Checked all the drivers, tried stamina mode (disables nvidia graphic card), tried different internet browsers (firefox, internet explorer), plugged the LAN cable directly to the pc (not to the docking station)... still the same thing.

At home I use wifi.... and never had a issue with freezing windows.

What actually happens is usually internet explorer or the outlook (2007) cannot connect... then this program is not responding...while others for sometime are ok... however after a minute nothing is responding... can't use ctrl+alt+delete command as well.

The only way I can stop this is to shut it down with power button.

I've checked the event viewer and there are some errors there... don't know if they could help you people.

Hope there is a solution.... cause I can't really work like that
Thanks in advance

It may seem obvious from your description that your NIC has a problem. Have you tried uninstalling that device and re-booting to install it again.

Hi.

Install the video card driver using this link.

If you're using ZoneAlarm, completely uninstall it to test. Or matter of fact, do this for any firewall you installed.

sorry for a silly question...what exactly is NIC???

About the graphic card.... I've downloaded the latest driver from Nvidia... although they state there specifically that Vaio notebooks are not supported. I extracted the files but could not identify the necessary .inf!!!!

Hi and welcome

Could you tell us what the event ID and source codes are of the relevant errors in event viewer?

Thanks

Oh... :)

Well...I have updated the drivers few times... the drivers for the docking station were downloaded from the sony site.

Will try again however.

I can't really understand why it could be the Nvidia graphic card though?? What is the connection? I mean i use it at home with no issues....

P.s. at work I am connected to a screen...via a docking station (in case this could be important)...

guys...I'm attaching you the extract with the errors that I had today... Hope this helps!

I was having that same exact issue and tried updating the nVidia display driver, which made the problem go away fo three days. But, alas, the kernel-power messages came back when the screen went black and locked up the PC.

This time I had the case open and saw what happened. The PSU stoppred, all fans inside came to halt at the same time. Power supply failure. Bingo, time for a new PSU.

Sorry, I didn't intend to show that there was a connection. I'm just showing you how to enable the Aero interface and have proper graphic acceleration for you video. Go to C:\NVIDIA and in the top right, search for *.inf.

Did you already uninstall your firewall?
