AU Laptops

every so often, my laptop screen will flash a little, then stop, and then it will start flashing again, this time very heavily! i dont know if ive bumped or pressed the screen to hard to make it do this, or if there is a loose connection somewhere…

I added a program to convert dvX to dvd and burn. Ever since my laptop swiches off whilst using. I have uninstalled the program and ran spyware. Checked battery ok. Just about to wipe everything off comp and start again. Oh i have restored twice prior to installation date also.
