Good luck, and let us know a bit more, please,
Please reply using a web browser, not a cell phone, so your messages will post... and more questions
What is your exact brand/model graphics adapter (ATI or nVidia or ???)
What is your exact graphics adapter driver version?
Have you gone to the vendor web site to check for a newer driver?
-If Windows, do NOT rely on Windows Update to have current driver information
-you need to go direct to the vendor web site and check updates for yourself
ATI Driver Autodetect http://support.amd.com/en-us/download/auto-detect-tool
nVidia Driver Downloads http://www.nvidia.com/Download/index.aspx?lang=en-us
Also, exactly what are you editing?

I am using windows 7 on a 64 bit HP Pavilion PC
Regarding the spec for the video card I have looked in Device manager and the display adapter is NVIDIA Ge Force GT 230M
I am afraid I would not know where to look for the other items?
I am afraid you are dealing with someone with far less knowledge than you about computers. My computer is an HP Pavilion i7 64 bit working with Windows 7. I have a NIVIDA G Force GT 230M Disply adapter.
I would not know how to get the codec or format info.
I posted links for you to read to learn about codecs, and also to programs that will tell you what you have, and instructions on how to post the information
People here will do their best to help... but you do need to read and do some learning to give information for people to be able to provide answers
How to determine your nVidia driver version
Right click in any open area of the Windows desktop
Select NVIDIA Control Panel from the popup window
Select SYSTEM INFORMATION at the lower left corner
Driver version should be the 1st line in Details
I have a GTX285 using driver 296.10 and Win7
I provided a link to nVidia driver downloads... but the first thing you need to do is learn about codecs and then tell us what you are editing
For file details, probably the easiest way is to download and install the free file info utility, G-Spot: http://www.headbands.com/gspot/
Then, launch G-Spot, and run one of your media files through it. The file's information will show in the G-Spot screen. It's probably best to just do a screen-cap of the program's panel, with the file's info. This article goes into one method of posting a screen-cap: http://forums.adobe.com/message/2643538#2643538
For the installed video driver, I like using a built-in utility in Windows: dxdiag . It will give you a lot of system info, and especially for the video driver.
If your installed driver is not the latest one, for your model nVidia card and OS, then I would download and install the latest version. Do this verification from the nVidia Web site, and do not trust Windows to tell if you have the latest version, as it will likely be 6 mos. out of date.
Also, as you have an HP, you might want to check their site for an updated nVidia driver. HP, Dell, Lenovo, Toshiba, etc., often re-package video drivers for their exact versions of the cards/chips.
Good luck, and hope that helps.
Did all that and the driver version is 327.23
I tried the downloading Gspot and it came up saying I did not have a file to open it. I went to the web to search for one but started getting a lot of Norton and other scanning programes i did not want so i shut it down.
HP site had nothing so went to the nvida site and dowloaded a scan which said I needed a lot of updates and wanted £30 to fix them.
