Hi\n\nBrand new system with windows XP. G force 4 video card.\n\nEvery time i switch on the mouse is frozen in the centre of the screen. The\nPC is not locked up as you can navigate with the keyboard. If you do this\nand go to Mouse properties - hardware there is no mouse shown as being\ninstalled.\nNavigate to close down and switch off, then back on again and the mouse is\nworking fine. It shows up as a ps2 mouse in properties.\nSwitch off again and back on and the mouse has gone again.\nThis happens every time. Each time it is there then it is gone. The pattern\nnever breaks.\nOn one occasion when the mouse is working i uninstalled it in device\nmanager. When i re started of course the usual thing happened and the cursor\nwas frozen. Restarted again and the PC "found new hardware" installed mouse\nand all was well. Switch off and on again and the problem is back.\n\nTried with the new optical mouse and another ps2 mouse i already had (old\none with a ball).\n\nWhy does my PC see the mouse then can't see it.\n\nAny ideas.
