20 Most Recent Biostar P4M890-M7 Motherboard Questions & Answers

id you recently upgrade your PC, change its components, or test a setting in the BIOS that now stops it from power up all the way? Here's how to reset your BIOS.

First of all, if you have, read the manual to the motherboard and look for BIOS or CMOS Reset.

Generally, the easiest and least fiddly method is to remove the power cord from the computer, open it and look for a button battery (usually bigger than the ones in a watch) remove it for for five or ten minutes. Theoretically this should work.

If no manual is handy and removing the battery did not work try the following:

Power down your PC.

#Locate a rocker-style switch at the back of your PC (if applicable), and switch it from the on position (I) to the off position (O). If there is no switch disconnect the power cord from power supply.

#Find the 3-pin jumper near the power supply on the motherboard, typically labeled "clear cmos" or "reset bios".

#Remove the jumper from the default position (typically connecting the 1st and 2nd pins).

#Replace the jumper to connect the 2nd and 3rd pins.

#Push the power button on the front of your PC once.

#Wait a minute.

#Return the jumper to its default position, connecting the 1st and 2nd pins.

#Move the rocker-style switch at the back of your PC (if applicable), to the on (I) position.

#Power on your PC with its front power button.

If it doesn't work go to alternate options.

#open Command Prompt , click Start Menu > Run > type CMD (enter).

#type debug (enter).

#then type this bellow code

o 70 10

o 71 20

type quit.

Have you tried a different monitor?

If it doesn't work only in the Bios, it could be that the monitor you are using doesn't support the resolution required to display the bios.

Do you have any results using a second monitor?

When you say "does not start", does that mean none of the fans spin, the hard drive does not power up, CD drive door won't open, no lights light up on the motherboard?

If any of these are happening, let me know. I would start by unplugging all the things you added except the CPU fan first and see if it now powers up.

If it is indeed powering up, but there is no display, perhaps the video card is not properly seated (assuming video is not integrated). Also, you did not mention if you had plugged in keyboard, mouse or any other peripherals.

Start with as little as possible and when you get power, add one item and check, then add another and check.

Let me know if you need more help.

You can get the proper driver utility from SIS.com also known as silicon integrated systems it is "sis uniVGA5 graphics driver" version 5.29. I had the same problem as you have: I went to that site and got the program. "NOTE" if you are running stopzilla, UNINSTALL IT BEFORE proceeding!
