In this case, what I will suggest is that you do need to reinstall windows.
I wouldn’t recommend anyone do this in a normal installation, but … since you probably need to reinstall windows anyway
Uninstall the following devices in safe mode (if you can) which will force windows to redetect & install drivers for the following.
Please ensure that you have the drivers, either downloaded from the web, or on CD available when you reboot/ reinstall windows.
In safe mode, in device manager, uninstall the following ->
All items under “display adapter” category.
System devices->“PCI to AGP bridge”
At which point, windows will probably have a heart attack.
If your mouse is USB All items under “Universal Serial Bus Controllers”
All items under “Mice & other devices”.
All items under “Human Interface Devices”
Reboot, let windows redetect a few things & install the drivers.
Reboot again, since windows always likes to reboot.
Hopefully now it will have detected your PCI to AGP controller & then your video card, your USB ports & hopefully your mouse.
Just a few quick questions.
- Which operating system do you have?
- What type of mouse do you have?
- What type of video card do you have?
- Do you know the model of motherboard and/or what chipset? (you can usually tell from system devices. It’ll have SIS/NVIDIA/VIA/INTEL in front of a few things
