Powers up no video and mouse stays lit when powers off


This is an old motherboard, with this in mind there are a couple things for you to try. Power off the system and unplug the power cable from the power supply. Remove the left side of you're case. Touch any metal surface to discharge possible static.
First clear the cmos jumper on the motherboard. See page 1-17 in you're manual for the location of the cmos battery and cmos jumper. Also see page 1-21 to clear / reset the cmos battery. (Don't forget to set the jumper back to normal after 30 seconds.
Doing this will reset the bios to its default setting.
If you added a graphics card to one of the PCI slots remove it.
(For now).
Re-connect the power cord for the power supply and power-on the system. If the motherboards built in VGA controller is working you should have display on your monitor and since we cleared the cmos the bios will want you to enter the bios to adjust all its settings.
If you do not have display than the onboard controller is defective. You can add a PCI video card into any one of the 3 (White in color PCI slots). It’s not uncommon for the mouse to stay lit. If you're mouse is plugged into a PS-2 port try un-plugging it when the system is off.
Then re-connect it with the system off. You can also buy a USB to PS-2 adapter. Most new mice and keyboards come with this type of adapter. See the link provided; http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=776087&CatId=469
If you're mouse and keyboard are PS-2 and connects to the system by USB, try another opened USB port. The next link opends to Biostar and you're motherboard;

My keyboard and wont work and PS-2 ports will not


They may well have blown. You can use a USB keyboard and mouse - cheaper than replacing the mainboard.

PS/2 PORT


There is nothing that can be easily replaced on a motherboard if your PS2 port has malfunctioned. Check your bios, if you have a setting labelled 'legacy mouse/keyboard support' make sure it's set to enabled. You should still be able to install windows while your keyboard is connected to the USB port. If everything checks out in your bios and you're still having this problem, it could be that you're using a USB to PS2 adapter, which causes some computers to glitch. Try another keyboard if you have one handy, it could simply be a compatibility issue with the windows installer.... rare, but I've been caught with it before.

PS/2 mouse port not working?


Hello fredbeer,

Besides the obvious checking with your device manager, you can download a port test kit HERE. That will be able to test if it's working. The other thing you can do is switch the keyboard into the mouse port and the mouse into the keyboard port. You should get some errors, if not, one of them will work and the other won't. Hopefully, you'll get the keyboard in the mouse port to work, so you know the port is working. Also, if you have any other PS2 devices that you can test it with.

Good Luck and don't forget to leave a rating based on my solution.

Thanks

Mark

ECS GeForce 6100SM-M usb issues


Hello,

Like always I'm sorry for I have to be the one who's giving the bad news. The problem you face is related to a complex issue with the keyboard and mouse receiver electronics. More precisely these devices emulate a standard ps2 interface but adapts it to work with a usb port. This emulation should work fine but has some limitations. A motherboard has some 2-4 usb main ports that can be hard wired to some 1-2 usb hubs mounted also on the motherboard. A urb hub has the advantage of replicating a usb port so more then 1 devices can be connected at the same time, sharing the same interface. Motherboard manufacturers use this to enable their products to have more usb ports available to the user. However there are some devices that aren't compatible to be used through these usb hubs and must be connected directly to a usb port in order to use the full bandwich. Wireless keyboards and mices, or usb to ps2 adapters are such examples. As hard as you may try these woun't work untill you replug them at every restart because they can't be properly initialised through a usb hub. most of these devices have been optimised for such uses and don't display such problems, but as you see not all of them.
The only solution in your case would be to change the usb port where you plug these devices. Maybe your motherboard has some 1-2 usb ports that aren't run through a usb hub. Those ports would work fine. If this doesn't help, then there's no other way to make those 2 devices more "compatible" to eachother.

Hope you'll be lucky with finding the right usb plug in your motherboard. Just try every one of them, reinstall the drivers if needed, and check to see if this solves the problem.

A USB mouse will work but the PS/2 mouse failed. What causes it?


Hi melch, On the PS/2 mouse, chances are that the surface mounted fusible link/resistor supplying the +5VDC is open. It is normally very near the PS/2 port and marked [0] or labeled F???. This can be verified by measuring the absence/presence of +5 at pin 4 of the connector. In some cases, it is the I/O chip that gets damaged. Re "only two(2)USB port" aside from the 2 rear USB ports, the Asus CUV4X-C has another pair of USB connectors that are normally connected to the front panel of the casing. It is located very near the motherboard battery. Re "...prompting...high speed USB port...", normally by updating your OS (say XP to SP2) or downloading/installing latest VIA 4 in 1 Drivers should make your USB 2.0 compatible. Hope this be of some help/idea. Pls post back how things turned up or should you need further information. Good luck and kind regards.

Keyboard/Mouse Plugged in NO VIDEO NO Keyboard/mouse plugged in VIDEO ???


Apparently there is something confilcting with something ot the ps2 ports are faulty! We'll need to find out! Try plugging up your system without the video card but the ps/2 devices plugged in! (we don't need to plug up hard drive, so plug them out if they are plugged in) When the system comes on(after your hear the POST beep, if the system speakers is plugged up to the motherboard). Try pressing NUM LOCK or CAPS LOCk to see if the light come on and off. If they do that means your machine is responding with the PS/2, if not then you need to find a PS/2 expansion adapter ot use a USB Keyboard and mouse! If you do get a response that means your ports are working and there is probably a confilct with your Video card! In that case, I assume you've already reset the cmos(if you haven't then do that). Also if you have an AGP port try an AGP Card, if you were using an AGP card try a PCI! Well the USB keyboard more than likely will work! try these out and get back to me! regards, babb
