I am running a sh*tty computer with Windows 98 and recently tried to install a better mouse, with a USB adaptor, instead of the awful serial one I have now. It didnt work, and even after disconnecting it, the computer starts in a strange mood. The background is all pixelated and the display is weird, as if it were in safe mood. I tried going to device manager to solve the problem and rebooted several times after uninstalling and reinstalling the mouse software. There doesnt seem to be any problems, conflicts, etc, but it keeps starting in this mode. Help, please!
