Question about ASUS A7V8X-MX Motherboard

1 Answer

Lock ups Several conditions cause my PC to consistently lock up: 1) If try to use laser mouse, AND the Cable Modem is engaged. (Note the laser mouse used to work just fine) 2) If I put in a USB memory stick in. I am running XP. Sometimes the computer will lock up at random. If I try to reboot, I only get to the "DDR 333Mhz" during bootup and it stops. I have to then manually shut the PC down, then unplug the cable modem, re-plug it in, un plug again, and then boot while modem is connected. The PC boots fine, and once it's ready to go, I plug the modem back in, and it works.... for an indeterminant amount of time. Lastly, any time I have to update Windows, or basically anything, the PC gets cranky, and I have to go through the gyrations above. I do have USB camera, Printer, and keyboard as hardware. The Flash drive will always kill the system even if all of the other USB devices are disengaged. Any thoughts, other than blowing this dang thing up? Thanks for any help, RV

Is the laser mouse USB? If so there is a grouping of settings in your BIOS that has to do with USB storage devices, mice, and keyboards. It would appear that your USB keyboard controller is already enabled but the mouse and USB storage devices are both disabled. If you need help navigating through the bios let me know or look it up on google.

DX4820 power supply


To my knowledge, the Power Supply used is just the common ATX form factor design.

Approximately 6 Inches Wide, 5-1/2 Inches Long, and 3-1/2 Inches Tall.

Needs these power cables;

A) 24-pin ATX main power cable
Newer power supply's come with a 20 + 4-pin ATX main power cable.

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20plus4

That is so the power supply can be used on a motherboard, that needs a 20-pin, OR a 24-pin ATX main power cable.

B) 4-pin ATX +12 Volt power cable.
Often referred to as an ATX12V power cable.

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

[Note color of power cable connectors does NOT matter ]

Note the Lock on the side of the power cable's connector, and matching Tab on the motherboard connector.
The 20 + 4-pin ATX main power cable, and matching motherboard connector; has this type of Lock/Tab also.


C) Needs at least 2 SATA power cables.
The Harddrive is a SATA unit, and I believe the optical drive (CD/DVD drive) is too.

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

Often has a Lock on the connector. Press to release when installing, or removing.

D) Should have at least two 4-pin (Standard) Peripheral power cables.
Misnomered as 'Molex',

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

E) Needs one 4-pin (Small) Peripheral power cable, for the Card Reader.

http://www.playtool.com/pages/psuconnectors/connectors.html#floppy

Also needs 300 Watts.
A Power Supply like this one would work,

I need instructions on removing the cover to replace the battry.microsoft wireless notebook laser mouse 7000.


  • Press the "button with the star symbol" while prying up the top cover of the mouse's body to replace the batteries. If the batteries have power, the LED on the underside of the mouse will illuminate.
  • 2 Plug the receiver component into an open and working USB port on your computer. Your computer should make a noise when the receiver is connected, and the system tray will show that you have connected new hardware. Some USB ports may not be compatible, so it is important to try several ports to find one that works.
  • 3 Press and hold the "connect" buttons on the underside of the mouse and on the receiver for several seconds to refresh the connection. An interrupted connection will cause jerky or inconsistent on-screen performance of the Microsoft Wireless Laser Mouse 7000.

    Hi, I can't remember what buttons to push on my keyboard to switch from one computer to the other with my belkin 2 port kvm switck? can you help me, Ive just set up the system in another office. Thanks...


    Short answer:
    There are two ways to switch from one machine to the other with the keyboard
    1. Press Scroll Lock key twice, then the Up or Down arrow key.
    2. Press Scroll Lock key twice, then enter 01 or 02.

    Long answer (from the manual posted at www.belkin.com):
    You can select which computer to operate by either the front-panel push button
    located on the top of the Switch or through hot key commands. Note that it will
    take 1-2 seconds for the video to display after switching. This is due to the
    refresh of the video signal. A re-synchronization of the mouse and keyboard
    signal also takes place. This is normal operation and ensures that proper
    synchronization is established.
    You can conveniently change ports on the Switch through a keyboard command
    sequence using the "SCROLL LOCK" key and up and down arrow keys. To send
    commands to the Switch, press the "SCROLL LOCK" key twice within two seconds.
    You will hear a beep for confirmation. Then you can press the up or down arrow
    keys to switch between ports.

    You can switch directly to any port by entering the Switch port number you wish
    to use. For example, if you press "SCROLL LOCK", "SCROLL LOCK", "2", the
    computer on port 2 will be selected.
    AutoScan Mode
    In AutoScan mode, the Switch remains on one port for eight seconds before
    switching to the next. This time interval cannot be changed.
    To enable AutoScan mode, press "SCROLL LOCK", "SCROLL LOCK", "S".
    Note: There is no mouse or keyboard control in this mode by design, in order to
    prevent errors. If it were enabled, the user could move the mouse or use the
    keyboard while the KVM Switch is switching to the next port. This could interrupt
    communication between the computer and Switch that might cause erratic mouse
    movement, or result in errant display of characters when using the keyboard.
    To disable AutoScan mode, press the space bar.

    Probem with Asus P5W DH waking back up


    Do you have a modem plugged into phone line - is a signal on phone line causing it (unplug phone line cable to try that).
    Could be faulty power switch on front of computer where the contacts are only a hairs breadth apart and the slightest movement/vibration causes it to contact (try this by disconnecting those two wires from the motherboard

    I'd try disconnectng any communication cables from the computer first. That would be LAN and Modem cables. If it still restarts, disconnect the keyboard and power down the PC. If it still restarts, then power down again before it is fully off, remove the mouse. If it still does it get a priest to do an exorcism
