Hopefully someone can help me on a bit of a problem I am having.  I wanted to upgrade my graphics card (was a NVIDIA 8500) so I purchased a NVIDIA 200 GTS to replace it.  I needed to buy a new power supply to support the new card (needed an output of 500W, old one was 350W).

I bought the new power supply and installed it.  That went okay, the supply worked fine with my old video card and everything seemed to be in order.  I received my new card (the 200 GTS) yesterday and stuck it in the slot my old card was in and now I have major issues.

My PC will not boot up and when turned on a beeping error plays.  The error seems to be one short beep followed by one long beep, pause, short beep, long beep, pause and so on.

I couldn’t figure out what I had done wrong so I took the new card out and put the old one back in but it still does the same error.  It seems like it doesn’t recognize either card at all.

I am hoping I didn’t screw up my pc beyond all hope.

My PC is a HP m9150f.  I unfortunately can’t give you complete specs because I can’t boot the computer up but here’s what little I do remember;

Windows Vista Premium

Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40 GHz, 2400 Mhz, 4 core(s), 4 logical processors

RAM: 3GB

NVIDIA GeForce 8500 GT 256 MB (old now)

Sorry, I know that’s not much.

Any help would be much appreciated.  Thanks so much!

I bought a computer a couple years ago I've been thinking about upgrading some of the components in it to bring it up to date.  

The problem is I'm not really up to date with PC hardware so I don't really know where to begin.

I am hoping if I post my PC specs you guys could give me your suggestions on what to get.

My PC is used mostly for the internet and word processing stuff but I also play PC games occasionally and I would like to keep that up,  my sister bought me the SPORE Creature Creator but I can't actually play it, I don't think my graphics card is up to it.
