Ok, so this might seem like the odysey of my computer's history, but any sort of detail might be important, because I have tried a lot of things....and nothing has been solved.
5 or so years ago, I bought my Compaq Presario SR1130NX from CompuSmart, which included an nVIDIA videocard (GeForce MX4000 AGP), Windows XP, a refurbushed monitor, (not widescreen) and the rest of the specs of the cpu can be found by typing the Compaq product name on google.
My computer was installed by Compusmart and then, after some many hours or so, my computer was completely installed and we took it home. My computer worked fine for many years.
Christmas of 2007, I think, I got the LEGO Indiana Jones videogame, not noticing that I was in need of video Shaders, something that my videocard didn't have. I vainly tried to install it, but no luck. So, in August 2008, I bought a new videocard. It was an ATI diamond, and kept on crashing and malfunctioning. After buying 4 or 5 different copies of the same thing, all with the same problems, we gave up with the ATI and bought an nVIDIA GeForce FX 5500 (PCI) in September of 2008 and installed it.
Here is where the problems began.
So, my computer starts fine when playing a game, then, after a couple of minutes once going as far as 20 minutes, the screen freezes, and the music continues. Then the music trills, then the music continues again normally , and then the game continues perfectly fine. This takes the space of 1 minute or so. It repeats itself every couple of minutes.
It happens in: Harry Potter and the Order of the Phoenix, Harry Potter Quidditch World Cup, Pirates of the Carribean At World's End, sometimes with Zoo Tycoon 2 Zoo Keeper's Collection. I would like to point out that these games worked perfectly fine with the MX4000, so it's not a problem of computer specs.
I have tried: to un-install and re-install my new videocard, to make sure that I had un-installed all of the ATI drivers from my computer, I installed a new memory module (I had 500MB of RAM, now I have installed another 500MB of RAM), talked with BFG (the brand of my nVIDIA) they told me to get an RMA ( I can't because my videocard is out of warranty), I talked with HP....they were useless, I tried to see if anything was wrong with my BIOS, nothing was wrong. I also updated my drivers....all of them.
None of those things worked.
One thing that I did notice, was that the onboard videocard, and my actual videocard had swapped info, therefore, I had my nVIDIA with 64MB and my onboard with 256 MB
I ended up solving that by deleting one thing that now prevents something or other of my onboard.
And I don't think it's overclocking because my computer doesn't feel warm at all, actually, when my computer does that...thing ( I haven't thought up of a name for it yet) my computer feels pretty cold, but not cold like freezing, just normal temp.
Any suggestions?
I may have tried other things that I can't think of the top of my head, and nothing works
Help!!! 
Thanks,
