Hello. I've a Dell Inspiron 1120 laptop. Lately it's been giving me a lot of trouble. The laptop suddenly freezes, everything on the screen just freezes, even the mouse cursor doesn't move! And then all I can do is force shutdown the system. During the moment when the laptop is frozen, the LED for the hard drive is off or just glows solid. I made a Hard Disc check up through Dell PC Doctor but there was no problem with it. The freezing happens everytime. Please, I hope someone out there can help me out since I'm not a tech savvy. Thanks in advance.
