My mouse getting power off while running windows, there by hangs computer

[Boggin]

It tells you at the beginning of that tutorial you have just run through that when an USB device has been installed and then removed, Windows hides the driver, so they are an accumulation over time which could cause Windows to load the wrong driver.

However, as I have said, the problem could be hardware or interference related and no amount of fresh driver installs will resolve that.

I don't know if you are using a Desktop that you may have on all of the time or a laptop, but a cold boot can reset the ports power state, as they can enter a safe power state to protect from power surges due to USB devices and this could be the cause of the freeze.

Unless you can try another mouse to eliminate the one you are using, there's nothing more that I can advise on this.

Hi, While i could gauge the reason that a still mouse pointer amounted to absence of driver, unloading the driver for the device by the windows, (having checked that by uninstalling the mice driver from device manager, and the mouse does not work, but pointer was there), i rebooted and the mouse driver was installed automaticaly.)i could not know the sudden behaviour of this auto power off of the mouse.
                         I uninstalled the latest drivers for mouse from logitech, i do not know whether this is a problematic driver or not. what is synapticc device driver. Ofcourse, the technician has installed at the first instance of window installation.

[Boggin]

The Synaptic device driver could be a generic pointing device driver.

Is the driver listed in Device Manager ?

[Boggin]

Been having a look around and the Synaptics device driver could be for your Touchpad.

I don't have it installed on my OEM Toshiba laptop as it uses something called Flash Cards for the Touchpad drivers.

I think I vaguely remember seeing it on my computer but can't remember where it came from and I think I uninstalled it - it certainly hasn't reappeared since a factory reset last June.

Some mice auto install it so it may have come from a different mouse I was using at the time.

Hi, You mean touch bad is only available in laptop, i think. I do not know why it was installed in my desktop computer. I also uninstalled now. Now, no more errors. But what about this ELan , i enclosed in the post

[Boggin]

The Synaptics driver may have been installed with the mouse the tech was using to set up your pc.

I have a pre-installed PS/2 compatible mouse driver installed, but have you ever used a mouse of that brand that plugged into the PS/2 port ?

It's difficult to know what the tech had used/installed, but this is what my Device Manager has -

Hi, How to find ps2/  part.]
              for your information, i use only ports on the back of the computer for mouse and keyboard. what is this driver for and what are the uses for that port. Now i could know that ps2 is old type of Pin used at the top of the computer back to run the mouse, of older type. I remember having that when i bought the machine years back.It has no usb type holder at the end, but a kind of round with fitting pins in it. Now , i do not think that i need that as i now use only pen drive type of usb to be used in usb port.
Update: I think you have a mouse attached to that port, and hence shown in device manager

[Boggin]

I don't even have a PS/2 port on this laptop and I think they are just preinstalled as legacy drivers.

Hi, Boggins ,
                      synaptic point device drivers.
                             Windows has its own drivers. Is it not enough, if those drivers are installed automatically on finding plug and play devices.?
                              i now know that when new devices are installed , it goes to a folder called preconfigured device folder and if you unplug and replug a device, the drivers are installed from this file, called infcache.1.I noted the size of this when additional device drivers are installed. The older one, which i removed had size of 7mb.
                                 What is this Elan in my enclosure

[Boggin]

This would appear to be an earlier version of what you have installed, but I don't know why you should have it installed on a Desktop PC.

If you are still in touch with the people who built your machine, I suggest you contact them for an answer.

Hi, i uninstalled as i found it be a laptop driver. the driver was not shown in the picture. It was anyway got installed in the program. I uninstalled this with revo uninstaller .But last question. How the arrow point comes in to being? Is it automated process? I do not mean the mouse moving but the pointer. How it comes about?

[Boggin]

I'm not sure what you mean by that.

[jraju]

Hi, I mean, when you boot the computer it is the mouse that comes first and moving that you get to naviagation to items . But , the pointer,like the arrow, does it need the driver? Since, when you uninstall the mice driver, your mouse does not move, but the arrow remains there in the screen with any movement. I point that as mouse pointer

[Boggin]

The pointer will always be there but it needs a driver to move it.

When you get a black screen the pointer is much enlarged which can still be moved around but there's nothing for it to do.

[jraju]

Hi, How the pointer comes there?. This is my query.Is it also one of the starting item or service in windows 7

[Boggin]

The cursor is part of Windows but this article will give you a bit more info, but not sure to what end.....
