I got windows 7 ultimate 32 bit about 3 weeks ago.
When I start my computer up, the mouse curser is either bigger than usual when i type my password in, or it is bigger when i am eventually in. when the mouse is bigger everything is slower, like for instance the right click menu take forever to load.
about a minute or so, my screen goes wierd, and everything is messed up.
I switch my computer off by the plug, for the power button on the computer doesn't work. it gives me a choice of safe mode...etc. i choose safe mode, then restart my computer in safe mode, on most occasions this helps, on others it doesn't.
sometimes i have sat for a half an hour restarting my computer in safe mode, leaving it for ten minutes and restarting it again.
