What kind of memfory do I need for a P4M80-M4 Motherboard? I want to install another card.

Sounds like the PSU. Can you borrow one to test?

Your motherboard is manufacturing defective. If the motherboard still under warranty, take it back to the computer shop where you purchase and demand for an exchange.

your hdd is crash or may be problem on power supply connector and cord connector try to replace it.

Hi, you can download the sound driver for your Biostar motherboard here:

Just look under "Audio" and click the right one for your operating system.
Thanks for using FixYa!

You need to install the motherboard's chipset drivers as well.
If you don't have the CD, then go to biostar's website to download.

I suppose you have already tried moving the geforce to a different slot. It this a card that requires being put in a particular type of expansion slot for video cards only? If so, do you have the geforce in that slot?

If not, put it there and try it again.

Does your PC also require the BIOS be "told" that you are trying to interface this specific video card? If so, then go into the BIOS by hitting the requisite key combination during boot, and then setting your BIOS to the proper settings for this card.

-a.

P4VMA-M VER 7.8

Go in BIOS change the setting in Advanced settings.

Do you mean you have already installed them? It sounds like the install didnt work correctly.
