|sounds like it could be graphics related. Can you boot into safe mode (tap F8 during boot, and choose Safe Mode from the list). If this works, you probably need to reinstall drivers, like graphics or chipset.|
if the problem is not drivers, it is probably hardware related. Drivers can be fixed. hardware typically cannot. How old is this laptop? laptops typically have shorter lifespans than desktops, because they get beat around more, and smaller size leads to poorer airflow and overheating components.
