Biostar P4M80-M4 Motherboard - Answered Questions & Fixed issues

You have a very old motherboard here. It only supports the older AGP 8x video cards. Good luck finding one of those anymore that is worth the price, and don't expect anything you find to be new in box. This is probably where your HD video woes start, although the board was never designed for the higher frame rates that HD requires to be viewable. As far as the processor goes, this board has the Socket 478 for Intel processors. There are no dual-core processors that are supported by this socket. Here is a link to an article that shows what processors are supported by the socket. Be advised, however, that depending upon the BIOS revision on the board, some of these may not work properly, if at all. Socket 478 Socket mPGA478B Really, if you want to view HD, it's time for a real upgrade.

Hello Alienware,Could be a few things.... such as the micro-fuses that have gone on the MB....But what I dont understand is this:...."Then I disconnect the 4-pin cable that goes from the Power Supply to the motherboard near the CPU and the pc turns on fine"How????You have just disconnected the cable from the PSU to the motherboard....it CANT turn on! LOL.Do you mean that the lights turn on?Or you hear the HD spin up (if you left it connected to the MB that is)?Please advise so I can help you more.

still on the cpu? if so becareful let the lockdown leaver up then take out cpu

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

Try here: Drivers

Disconnect the hard disk and reboot - wait for its absence to be detected then shut down the pc , reboot and go into the BIOS and make sure the AGP is enabled. Shut down the pc again, insert the new video card, connect the monitor to it then start the pc and go into the BIOS - now you should be able to disable the onboard one.
Connect the hard disk and you're good to go.

You have not mention your Operating System(OS) on your PC System.

To get USB 2.0 support for VIA Chipset Mainboard
1. For Win 98 OS, you have to install "VIA chipset USB 2.0 driver"
2. For WinXP OS you must install, at least Service Pack 1, (recommended you install the lastest Service Pack 3) to to get USB 2.0 support.
3. Install the VIA Chipset drivers for your Mainboard ie "VIA Hyperion 4-in-1 driver v5.12A".

Hope it helps.

That is the smell of blown capacitors either from the motherboard or the power supply.

Press F2 at startup

The chipset i fried if you don't get any beeps at all. You'll need a new motherboard.

thank you for using fixya

This is an older board. The VIA chipset pre-dates dual channel memory support. If your board is working fine, this should not be a concern.

For problem #1 you need to be sure you have the proper codec installed for playing the movie..you can obtain codecs from the internet...also...do you know how much memory is installed on the video card..you may need more...the more video ram you have..the better the picture and the way it is buffered..as for problem #2, you can go to the manufacturer's website for the make of soundcard you have...or you can check for it at microsoft.com....as far as an agp card...go to the biostar website to see what they recommend...you can download the user manual here for the motherboard also..which can be very helpful in setting up the m-board

Here is the specs of the memory that you can use for this motherboard.

2 x 184-pin DDR SDRAM
PC3200 (DDR400) DDR SDRAM
Maximum 2GB

I would actually try checking your system components are installed in the right way. then, I would take the battery off and put it back the next day. then,i would replace the cpu.
However, socket 478 motherboards are Very Cheap nowadays so i wouldnt lose sleep over it.. However, you should keep trying and maybe it'll fire up someday... someday.. Good Luck and I hope this helps!

dude make sure that the ram is compatible with your motherboard if u provide the details of the Mobo and the ram i can then tell u if its compatible.other than there can be only one prob ram not working

try different ram, or if you have multiple sticks of ram try one and then another seperate. i once had the same problem
