Hard drive and cursor freeze

try a hard reboot

if the cursor is moving by it self you do have a virus. When you restart the computer bring it up in safe mode and check for a virus using maleware byte from Cnet.com

You can likely free the power button by getting in the crevices (long nails work great) and pulling the power button out, or clearing contaminants. Additionally, you might have to access your hard drive through a computer and delete some app data or pictures to free memory and solve the freezing problem.

Mine kept doing that to, I had to totatly shut done and start over

not sure but hope this helps

I have an apple android tablet and it freezes at the android with black backround

time to save everything to another save source and replace that hard drive
use a solid state hard drive as a replacement as there are no moving parts to wear out

Close open apps - could be something else hanging up everything (try keyboard; alt+F4, etc) if no luck try reboot, make sure is plugged in before power up

check for a virus

A few things to try. Check the event logs on your PC for Hard drive errors. If the lockups are random they could be caused by bad blocks on your drive in a paging or system file. If you see disk errors, replace the drive immediately and make sure to keep proper backups. Next, update all drivers, especially the video driver. Often lockups will be caused by Video driver corruption. Dont be scared to install beta versions of drivers for your laptop in an attempt to resolve the problem. Next, search out a utility boot CD from the internet. There are several, usually running linux but most contain a memory test utility that you want to run for a long period of time (several hours) to see if after a stress period you start getting memory errors. Next, search for speedfan on google and install it to monitor the temperature on your processor, this problem could be caused by dust buildup on the processor heat sync or cooling fan. Generally it would take some time to have this problem lock up the system, however, after the first lock up and reboot subsequent lockups would happen more quickly. Many laptop repair depots will do a service for under $100 where they will dissassemble the machine, clean the heat sink and fan (or replace it) and apply new thermal grease.
