my brother has a packard bell pc he's had it in storage for 3 weeks while he moved. he turned it off then packed it nothing out of the ordinary now hes moved and put it back on it wont start up the screen comes on etc and the keyboard lights up but nothing else. he said when he turns it off again he gets all speckles over the screen before it goes off but the lights on his keyboard stay on any one with any ideas as to what might be wrong thanks
