FPS drop in multiple games with X1900GT!

I have 2GB's of DDR2 6400 ram (G-Skill) and here's my PSU..

I just found some drivers on my motherboard's site..

When I tried to install it, I got this message...

The software you are installing for this hardware:
X1900 Series
has not passed windows logo testing to verify its compability with windows.

Then it gives me two options: Continue Anyways or STOP Installation, and it also gives me a big disclaimer scary thing about how continuing can kill my computer. Should I just continue anyways?

Those are old drivers, get the newest ones here (pick your version of vista):

32-bit Vista
64-bit Vista

naaah, the E4300 is a good pcu and will run the 1900GT just fine.

ive had a simular problem 2 this, they way to solve it is to lower your graphics in the ati control panel! COD2 has lots of fog which is a FPS killa tbh imo!

Sorry I will link the xp ones then. 32 bit right? Or are you using 64 bit?

EDIT: Here, bookmark this page for later use. Pick your own version of windows:

Do you have access to another PSU, just to try at this stage? Yours should be OK, but if you have one thats not so stable as it should be under load, then that will cause problems. Personally I would go for something with a little more than what yours has.

Also if you're not playing online, just try disabling your AV and firewall. You shouldn't need to with a system of those specs, but if it makes a difference, then try reinstalling them.

Can heat be the problem here? I touched my video card after a two hour session of trying to play and going online and it was really hot. What do you guys use to monitor your heat in your CPU and stuff? I Dled a program called Everest but it cannot detect any sensors.

What brand is your video card? Some manufacturers do not include thermal monitoring capabilities (like mine).

The brand is Sapphire, it had the most reviews and so I guess it was popular so I chose it. No I do not have a sound card by them, I guess I'm using whatever is on the motherboard, I have Realtek drivers installed right now.

As of now, I have two choices that I can see.
1. Return this card and get a 7600GT and hope that the 1900GT was at fault.
2. Get a new PSU and return this FSP one, this antec 500W one looks nice...

But the thing is, I don't know how I'll diagnose what the problem is. I was going to put this card in my neighbor's computer, but his PSU is a 350W one. His handles a 6800 and two HDs, so I don't see how mine can be at a loss for power.

Monitoring programs are designed for specific sensors. If your sensor isn't supported by the program, it won't show anything. So make sure you get a monitoring program specifically for your hardware.

Also, what kind of cooling do you have in the case. If you have a place for fans, especially at the back of the case, get one. Because those large cards, like the X1900XT run hot and need plenty of air flow inside the case. And Nvidia chipsets run pretty warm. If it is a P6N Platinum, the heat pipe system on the chipset of that baby gets really, REALLY warm, let's just say HOT! You need ALOT of ventilation for that. I bet the less than platinum chipsets get plenty warm too. So get plenty of ventilation on your case.

Personally, I would not have gotten an ATI card for an Nvidia chipset, especially an Nvidia SLI chipset, the 650i, like your's has. You have no SLI upgrade path. You can't do Crossfire on an Nvidia chipset just like you can't do SLI on a Crossfire chipset.

here is a picture of what he has:

Oh and a 7600GT would have much less heat output right? And demand less power as well?
