Is it my graphics card?

Well. I recently built my computer about a month ago, didnt want to share the other one with my parents.
Anyways I also made this online game called Goomba Online.
Because of this new computer, I for some reason cannot run my client or server at the same time.
I figured it was game maker's doing, but it wasnt.

Basically, only for my client and server, I cannot run both at the same time, I can only run 1, and thats not good
since I wont be able to test. Would you guys think its my graphics card?

If so what kind of video card would you suggest?

Sorry cant get my specs now, Il post later but do you guys think its the graphics card?

Its a e-GeForce 7300GT, 265MB
Dual 400MHz RAMDACs

get a ATI Radeon 8000 if u r gonna get a graphics card.

Will it fix my problem? Is it better than my current? Please provide details.

Try to tweak the small problems and if still noting get a Nvidia 8 Series.

Argh, you gotta be positive if its the graphics card or not, I could just be waisting money here.

Well maybe you could actually tell us what's wrong instead of saying "It doesn't work". Is there an error code? Will it just not launch all together? Did you try putting french fries on your hard drive?
I'm pretty sure it isn't your graphics card, but it could be. That's why we need more details to make sure
Radeon 8000 sucks anyways. That thing is old, and cheap. My computer came with onboard radeon X200, and that was 3 years ago XD.

Well when I ordered the parts it was an athlon 6200.
When I run 2 instances, one will not run. It just simply closes, thats it. It doesnt show the window or anything.
In the processes window, it shows the running process for maybe 1 or 2 seconds, and thats it, it will just go away afterwards.

Ive done almost everything:
Restart 10-20 times
Run in safe mode
Changed the graphics card
Ran in admin
Run as admin
Run as a differrent user
Run as a seperate process
I even reinstalled windows for gods sake, and I used a differrent XP cd!!!

What the hell is wrong here???

Soleria - 5295
AMD Athlon64 X2 5200+

Wow. Ok yea, that's just weird. I'm guessing you can run the server and game on your parents computer, is that one XP too? Ok so say, you run the server. It's running, then you run the game. Does the game pop up and close or does the game run and the server is the window that closes? I mean it's a possibility that your computer thinks its running the instance already, and doesn't run it twice because it is already running. Just a guess.

In the processes, it runs for a split second or two and just quits.
And now its not just my client and server, its for other game maker games too.

how much Ram do you have?

100% positive that your problem is NOT the graphics card. Your GPU may be a little dated, but it's definitely MORE than powerful enough to do such a menial task.
