Hey nu2dis,

That MSI NX7300 (geforce 7300), is a PCI Express card.

Unless you've got a board that's at the most, 2yrs old, you probably won't be able to use it unless you upgrade.

A good site to look for a card that may fit, is , or

IF you post your exact motherboard model, I could tell you what you would need.

But to tell the diff between AGP and PCI,

AGP will be a slot, that looks diffirent then the other slots. (the board will have 2-4 slots that look idential, and those are usually PCI, and then it will have one that's actually set back a bit further, and may even be a diffirent color, if its not PCIe, then it's AGP). ANOTHER thing you have to look for to, is the speed of AGP. Most cards today are AGP 8x. If you're board is say...older then 4 yrs, you prob have AGP 4x, or AGP 2x.

If you're still unsure, post the model of board, and I'll help you out.

If it is quite old it may not have an AGP slot in that case you will need to buy a PCI card for it.

IF, and I stress IF, you decide you simply want to replace the motherboard, get one that matches your processor socket, and be super careful when removing, cleaning, and replacing it.
The question will be, will your new motherboard fit in your case. Simply get one with similar specs as your current one.
most MSI products fit inside of an acer case though.

My problem is that i dont know how to download the sound device . I have MSI computer.But i dont know the type of my sound card .I will be grateful if you help me

If the sound card is in one of the slots you may just take it out and read the brand and model number right from the card. If the sould card is part of the mother board it will not be in one of the slots but be part of the board itself . If that is the case go to the MSI site type in the model number and download the drivers and sound from them or loook up what kind of sound and go to thheir web site.  Any more questions as I know this is not such a complet answer , please write me back.

Multiple display problem

Hello. Your driver software was 71.6MB large. It not only included the driver software but secondary software for you to control & setup dual monitors. The package came with a HDMI connector which is used to connect the HDMI femal port to VGA port, if the monitor does not have a HDMI male port. Currently the reason you can not see your display is because the signal comming out of the video card is set to the other port on the card. Once you switch to the other port you'll have display on your monitor. Open control panel, than open display. Display Properties will open on your desktop. Click settings than click advanced. You should see another tab that reads something like, NVIDIA® nView Multi-Display Technology. (I'm guessing because I only use ATI's software) I can't load your driver software on my current system. The two cards may be different but the software is similar. This Nvidia tab is where you set up your monitor or monitors. Once in this advanced portion for your video card you can set which connector from the video card will display on what monitor. There will also be a ton of settings you can adjust, from color to 3D & other options. You must have an icon by your clock as well that allows you to open the standard display properties or the advanced display properties.
