    Good day herickpalomo,

    The Biostar P4M800 Pro-M7 board already has a built in network (LAN) connector. See pages 2 & page 3 from within the manual.

    See its location of the built in network (LAN) connector.

    You can download the manual by clicking on this link;

    Unless your onboard LAN has failed or you do not need a second PCI network card. If you are 100% sure a piece of metail found its way into the PCI slot, that could short the board when powered up.

Problem for Biostar P4M800 Pro-M7 Socket 775 mATX MB I think i made a shot circuit in my mb is posible to fix it only the fans are running, no BEEPS. no beeps no video. cant enter bios help

I have the exact motherboard in a everyday desktop. I ran into this issue myself. The video card was bad. It didnt give me any error beeps either. So, I popped a used AGP nvidia geforce 5200 in the slot and bam, it was back up.

However, make sure your hard drives are spinning. If they are not, there might be another issue at hand...

Hope that helps and let me know what you find
