The first thing to try seems a new videocard.
Every time I start my PC, there are white lines across my screen, then sometimes green boxes come up which are quite small, and then it comes up with the windows logo, underneath says Please Wait, and then restarts and keeps doing this over and over again. The only time I don't have problems is when I enable Safe Mode.
WHAT DO I DO????
OS: Windows 8
PC: Dell XPS 420
