Hello! I have a Toshiba laptop that I've had for about 2 years. The cursor has recently became frozen or disappears altogether. I've tried using F5 and it does nothing. I've turned my laptop on and off and it still won't work. I downloaded an antivirus software to make sure there wasn't some sort of virus on my laptop preventing the mouse from working as well, and that still didn't fix it. I've discovered if I hold down the left click button and drag, the mouse will work, but that's the only time and it's extremely aggravating. Does anyone know anything else I can do that I haven't already tried that will solve this problem? Please help me if you can. I need my computer for college and I have things I need to do ASAP, and this cursor situation is preventing me from doing it. Thanks in advance!
When was the last time that you defragmented your hard drive? Seems like it has some bad sectors on it. Try booting up into Safe mode and see if you have access to command prompt line. When you go there use the chkdsk : /p /r command to repair your disk.
You could also try to extract your files through Linux Live CD since the problem might be hidden within your hard drive.
If you have a suitable PC company you can trust, bring your laptop to them in order to make tests of the RAM and cooling system because sometimes not enough cooling can make your video chip to work unproperly.
