No matter what I do, when I try to install this graphics card on my Compaq Evo D500 motherboard, the following symptoms occur:

>> Spontaneous freezing in Windows XP from initial loading to any time, causing a reboot, with the window "Windows has recovered from a serious error." It then tells me my graphics card's drivers got caught in an infinite loop which made Windows restart to correct the problem.

>> rare graphical glitches in Windows XP and application windows; checkered green color error

>> Longer than normal hang time in applications

>> Spontaneous display failure; monitor loses video input

>> Spontaneous graphical driver reboot (monitor blacks out for a few seconds then turns back on, with resolution lowered to basic 800 by 600 pixels)

>> Immense graphical glitches in 3D applications such as games

>> Freezes and restarts computer when trying to generate three dimensional objects

Now, i'm hoping that there is a fix, or a proper driver (the installation disk says it comes with one, but doesn't. All tested drivers, including nVidia's, cause the above problems)

Is the AGP slot just not the proper version for the graphics card? Is the card known to be bad? Should my motherboard run it just fine? Any and all help would be greatly appreciated, as this was an expensive christmas gift given to me by my father, so I can play games with no framerate issues (as PCI graphics cards can only do so much).

The current graphics card I am running on is a GeForce MX4000, with my 7600 waiting for help.

I'm sorry, but there doesn't appear to be an 'edit post' option, so unfortunately I have to double post.

After scouring the net, I've finally found something that could be the issue. Apparently some video cards require a rather high wattage for a power supply. Could this be the issue? As I'm reasonably sure that my current power supply has a max output of 250 watts. Is there a power supply for a Compaq Evo D500 that supports the proper voltage requirement? (What is the 7600GS TD256Z's voltage requirement)?

450W at least will be good.

PSUs are pretty much "compatible" with anything.

[Gruntsworthy]

PSU=Power Supply Unit?

[Carbon]

Yes.

[Gruntsworthy]

Um, great. Now I have someone telling me that PSU voltages don't matter! It's my dad, and he's been immersed in computers for many years. He studied electronics in college, and knows alot... I'm so confused!

I'm also trying to get a hold of a local computer shop to see what he has to say on the matter.

Is there any other explanation other than the power supply's voltage?

[Carbon]

It's not the voltage, but the wattage. You need at least 450W, with 500W probably being the best choice. Voltage in an electrical system just means the rate of speed of the current passing through a conductor - something relatively irrelevant at this point, where the amount of current is what's limiting you.
