I'm running an Nvidia FX 3500 PCI 256 vram on a Gigabyte Mobo with an ATI video chip set. The computer came with an ATI card and i replaced it with an OEM. It was fine, recently I experienced matrixed dashes in rows anc columns as well as triangluated windows in the Vista OS. Problems stopped when I re installed the ATI card.

so the PC mobo has and addin, PCI card sound"?
2004 PC mobo relic, now and 13yo to you.
no card told. (fail)(buy only w7 allowed card if must)
you did say CARD so means NOT ON-BOARD sound chip.
relic P4 PC. mobo
v1.0 mobo?
this trash mobo uses EOL DOA, via chipsets, that do not allow w7
Integrated Realtek ALC662 audio CODEC chip
this chip set is dead too, from maker realtek.
if you knew that, and added a secret sound card.
this mobo only does windows 200o to XP says so on page one at gigabytes this mobo.
so w7 does not belong hear unless replacing every thing there that fails 1 by 1, , pain. ive done this vast times, for folks willing to.
last xp driver is here for realtek

as a rule only this OEM maker PC can make there sound chips work (as a team of parts) not simple as many think, even has mixer chips and more, all custom to maker.
yes cards work better,
on this mobo the VIA chip and codec chip must work or sound will be dead. and is common this. lacking no vista driver up, ever/

this mobo has no SATA ports nor any PCI express card slots at all.
and finding PCI (non express) cards that can run w7 can be hard.
for sure now. yes possible, with careful searching specs of relic PCI cards.
also the VIA chip dead makes The ethernet port dead too. and usb dead and IDE drives dead,vista up.
never buy VIA chipped mobo. or pain is all there is. no drivers.

Good day sir, Yes, its a standard PCI card that can be placed on any PCI slot on the motherboard.

nVidia is the better choice.

Definetly the ati one. 120 stream processors is really good and it has
direct x10.

The MSI KT4V motherboard is an AGP board supporting 4x/8x AGP. You cannot use a newer PCI-Express Video Card, however an Nvidia GeForce FX 5500 either PCI or AGP will run just fine in it. The NVidia FX 5500 doesn't come in PCI-E. Additionally The ATI Radeon 9550 doesn't come PCI-E so you should be safe with AGP versions of either. I should note however, that you'll get better performance out of the ATI Radeon 9550 as opposed to the NVidia FX 5500.

I hope this answers your question,

Well, I can solve it but it is somewhat bad news. Basically your video card is not powerful enough. Here are the ATI specs from the EA website;

ATI Radeon™ series

9500, 9600, 9800

X300, X600, X700, X800, X850

X1300, X1600, X1800, X1900, X1950

2400, 2600, 2900

3450, 3650, 3850, 3870,

4850

and here are NVIDIA

NVIDIA GeForce series

FX 5900, FX 5950

6200, 6500, 6600, 6800,

7200, 7300, 7600, 7800, 7900, 7950

8400, 8500, 8600, 8800

9600, 9800, GTX 260, GTX 280
I would recommend buying a new video card. You can pick up a NVIDIA 8400 thru 8600 for about $30 or $40 from Frys.com or newegg.com sometimes cheaper with rebate.

They are fairly easy to install.

Good Luck.

When you power on your computer do you hear any system beeps from the PC speaker? When the computer is turned on it will run through a system check and one of the things it checks for is the presence of a working video card. One beep typically means everything checked out ok and your graphics card is working and it will continue to boot. If you are getting past that initial test I would next look at the monitor and see if it can handle the signal that is being sent to it. Are you not getting any of the boot up text display?
