Vista - Help with Flash incompatibility card

In Nov. I purchased an HP desktop computer with VISTA from Best Buy. I specifically asked for a computer that would play games well. Now the last two games I purchased from Big Fish games dragged in low motion. I contacted their tech and he told me:

"Unfortunately, we've noted a lot of problems with the 6150 card that you have, particularly with Vista machines... the card is NOT compatible with Flash, which games like Laura Jones and Woman's Murder Club use. Do you have a computer with Windows XP loaded, by any chance?"

Is he insinuating my old beat up computer with XP would play it and Vista can't?

Is there anything I can do to fix the problem?

Here is part of my DXDIAG (The board can't handle it all)

Assuming you have no drivers that conflict with SP1, you maybe want to start with upgrading to that. Second you could check the nvidias website for a newer display driver. As well you could run the Directx web updater which will update files as needed. One more option could be to check that you have the latest Flash version, and if you do, maybe go back a version to see if that makes a difference. If you need more a detailed explaination on anything just ask.

SP 1 and SP2 I assume were installed on my computer before I bought it. Windows does auto updates all the time. I just downloaded the latest NVidia. I just now downloaded the latest Flash. Haven't tried the game again yet.

SP1 will show build 6001, there is only an SP1 for Vista, no SP2 yet. Try running Windows update manually and see if its there.

How do I do that?

Click the Start button and in the search bar just type in "update" and Windows Update should appear (or you can find it under All Programs)

Then click Check for Updates.

OK I did an update and saw several NVidio updates but nothing with 6001 update

Go ahead and install those updates. SP1 may not show up until you are caught up with other updates. After installing those wait a few minutes and try Windows Update again. Alternatively you can download SP1 from here: Download details: Windows Vista Service Pack 1 Five Language Standalone (KB936330)

I downloaded SP1. Now what?

Just run the file you downloaded and let it update. It may take anywhere from 45 mins to a an hour or 2 depends on the speed of your computer.
