I have windows 7 home premium 64 bits. Recently I installed Norton 360 and after using disk optimization my laptop kept crashing and even on using any of the options from the Norton.
I formatted my laptop and again reinstalled. It worked fine for 1-2 days and then again my laptop crashed and shows me blue screen every now and then even if I don't start and program and keep it idle with even opening Norton and even when I tried to open Norton it didn't open.
So used NPE (Norton power eraser), it displayed that my laptop had old version of java so I uninstalled the old java and installed the latest version. After this Norton ran on my laptop but again when I used disk optimization and backup on my laptop crashed and showed a blue screen. i have not used any other option because of crashing problem.
Please tell me what to do?
