CS4 and Dell Latitude D820

Question

CS4 and Dell Latitude D820
Just wondering if anyone has the same Laptop model as myself and is running Photoshop CS4 on it with no problems?
With so much being said about differing configurations playing a part in CS4s performance, and with laptops offering perhaps the most uniformity in terms of hardware makeup across any two units, I thought it might be illuminating if we could find two systems of the same model and specs where one (i.e mine) has serious problems with Photoshop v11 and one (somewhere among you fine folk) that does not?
Obviously manufacture batch numbers could vary but, apart from that, Im thinking any hardware variables here should be at their most minimal? We could then begin to establish (perhaps) what other than hardware it might be that sees one system working fine and the other not?
For problems experienced on my Laptop system please System Setup 4 on
this page.
Would be interested to hear from any Latitude D820 users who are not experiencing these problems.

Re the Display driver.
I contacted both nVidia and Dell. Nvidia refers me to Dell as sole provider of driver.
Email reply from Dell tech support (on my asking for any news on new driver):
"I would like to bring it under your notice that I do not have sufficient update to provide you on the shortly available Drivers of new version".
I did speak with a Dell engineer who tells me: Dell can only package and release any new driver as and when updated drivers are provided by Nvidia.

Well basically its not the problem with the Routers firmware. It might be due higher level of security which you have set on your Router or it might be your Intel Pro Wireless is unable to communicate with your Router. In this case you need to lower down the security on your router to WEP or WPA Persoanl . If you have already lower down the security on your Router then it might be your Intel Pro Utility which is unable to communicate with your wireless network. In this case you need to disable Intel Pro wireless utility on your Computer and use Default Windows XP configuration utility to connect to your wireless network.
Opene Intel Pro-Set wireless utility on your Computer, On the top you need to click on "Tools" tab and below you will find the Option "Use Windows to Manage WiFi" or "Use Microsoft Client" and click on Yes. So it will disable the Intel Utility. 
Now in the system try Locate your "Wireless Network Connection" icon, right click on it and select "View Available Wireless Network" , locate your wireless network, input the security and click on connect. Now check if you are able to go online.
