I have always left my computer on overnight after I disconnect from the internet. I have noticed over the past few days that when i switch the monitor on the screen is blank and I have to re-boot. Other times the mouse arrow indicator has frozen on screen and have to reeboot also. any suggestions about what this can be. I am not really tekkie. Thanks.
My son usually maintained myc computer for me but he has left home. Can anyone give me advice about basic maintenance to keep things running smoothly.
