    Old computer Problem

    Hi..
    I'm fixing a computer for a friend. He requested that i buy a 5 port USB PCI Card, and a CD burner. The CD Burner Installed fine but when i insert the USB card, the computer refuses to boot (monitor doesn't turn on)
    I know the mobo is a DFI K6BV3+ and i think the cpu is a K6 500mhz....

    (I'm not real good with old PC's...considering i was about 10 years old when this computer was brought out.....)

    I have tried
    • Connecting it in every PCI slot
    • Flashed the BIOS
    • Tried card in another computer, it works, (no problem with card)

    well that strange but what spiec on video card? I think it video card pull lot watts from psu which cause less watts for another electirc in computer.
    Try remove cd burner and put oringally cd driver and try with usb card if it work mean PSU is low.
    sorry for my bad grammar!

    Where would you get the idea that his power supply is bad? If adding a 5w pci card makes it unbootable it would be completely unstable all the time without it anyways.

    I really don't know what is going on though, I would need to see it happening and watch everything to figure it out. Just don't have enough details.

    Yeah, sorry about that....This is all i know. I was thinking that it might have something to do with the mobo IRQ list
    "I know the mobo is a DFI K6BV3+ and i think the cpu is a K6 500mhz...."
    That along with a 4GB HDD and CD Burner.....

    Think the mobo may be so outdated, that it doesnt recognize the USB PCI card?? (Dont know if its possible)
    Do you have any other current-date PCI cards that you could test in the mobo?

    Could be, I am pretty sure it has to do with some bad option in the BIOS, but I don't know what a lot of those options do.

    According to http://www.motherboard.cz/mb/dfi/K6BV3+66.htm this has onboard USB, if that is correct, have you tried disabling the onboard USB via the BIOS?

    Is there a BIOS option in there for the PCI type to use? If there is, try PCI 1.1 or the highest version available, instead of PCI 1.

    First thing to do is scratch that "IRQ conflict" idea. That's an urban myth.

    Also, the board's hardware level of PCI support is a given, and it's at least 2.1. The board's PCIBIOS will also be at least 2.1, but that all doesn't matter zip.

    What exactly is happening? Does the board not fire up at all anymore with the USB card in? Or does it show initial POST screen, and then doesn't proceed to load the operating system?

    Your next attempt should be with a USB card that uses a VIA chip if the current one didn't. Alternatively, your next attempt should be with a USB card that doesn't use a VIA chip if the current one does - the idea being that with the board having a VIA USB controller integrated already, it might fail because it either doesn't handle anything but VIA USB controllers, or because it confuses added VIA USB controllers with the onboard ones.

    The computer turns on, beeps but the monitor doesn't turn on. The computer doesn't continue to boot. (No HDD activity)

    I found an old ASUS adapter and plugged it into the USB connector on the mobo. Now he has USB's. But i would still like to install the PCI card considering that he paid for it.....
