Installing Windows 7 on HP Pavilion a6720y

Instructions for upgrading a Pavilion a6720y to Windows 7

HP was of NO help and basically told me that since the PC came with Vista, they didn't have to support Windows 7. The jerks wouldn't even point me to where I could find the right drivers!

Nevertheless I finally found the correct drivers. here's what you need to do:

1. Before upgrading to Windows 7, download NVIDIA_3D_Vision_CD_v1.13_WinVista_Win7_EMEAI.
   
   You will need this to get the correct drivers for LAN and video. Without it, you will have an unstable PC with little to no internet connection.
   
   Download it from here: http://www.nvidia.co.uk/content/DriverDownload-March2009/confirmation.php?url=/Windows/3d_vision_ste...
2. After upgrading, install NVIDIA_3D_Vision_CD_v1.13_WinVista_Win7_EMEAI.
3. When you run Windows update, HIDE any suggested updates to the followin, because Windows Update will attempt to install older drivers that won't work:
   
   nVidia - Display - NVIDIA GeForce 9100
   nVidia - Network - NVIDIA nForce Networking Controller
   nVidia - Other hardware - NVIDIA nForce System Management Controller
   NVIDIA Corporation - Storage - NVIDIA nForce Serial ATA Controller
   
4. Allow Windows Update to install all other updates.
5. Install the updates from HP's website: http://h10025.www1.hp.com/ewfrf/wc/softwareList?os=4063&lc=en&dlc=en&cc=us&product=3856272&lang=en

That should get the job done.

Glad I found your post. I'm in the same boat, but it would appear the above didn't help. I no longer have network lockups, but I very regularly get blue screens referencing an error with nvlddmkm.sys (which I beleive is related to Nvidia).

I wonder if it's because I'm running a dual-monitor setup?

Wow so happy to have found this thread, thanks a lot. I'll try out those drivers, back to Vista right now since the network disconnect problem was so frustrating.

@MarcusF- I'm having the Bluescreen problem too and I'm not using dual monitors. I'll contact Nvidia support and see what they say but I doubt HP will do anything. I've been talking to HP email support for days and they keep saying they're updating the drivers which I highly doubt looking at the tone of the support guys.

At the end, I'm definitely never buying another HP again. This was just clearly stupid, they should have the drivers available for Windows 7 since I bought this PC when the Win/HP deal was going on (Buy a HP and get Windows 7 upgrade free, but I bought it a few days before it was launched). Just surprised how a company like HP could do this.

Does this work???

I tried this and it did NOT fix my wireless internet (it drops out after a few minutes) problems.

For the bluescreens, install this

http://h30434.www3.hp.com/t5/Lockups-Freezes-Hangs/Driver-update-for-Win7-USB-issue-on-nVidia-chipse...

All or most of the drivers mentioned above are on Windows Update

windowsupdate.microsoft.com  (Check for updates, opt in on all optional and recommended updates)

I followed these steps without any success. The System Interupts still takes between 40 and 50 percent of my cpu. Any other ideas? If there truley is no fix for this I personaly will never buy another HP product. The OS has been testing for over a year. Things like this should already be solved.

Same problem here.

I have even tried swapping out the video card...That fixed the bluescreens but everything else remains.

System is always running near 100% CPU, slow, video issues misc programs not working right (citrix). I just did a nuke and pave, same result. There has to be a flaw in the chipset drivers or something.

I figure it is something with the drivers as well. I have tried every update and every tool I could think of to find a working driver but also without any luck. Anyone have another idea before I completely loose my mind.
