I have an Asus G72 laptop and I have been having minor problem that have become more constant all of a sudden. My first problem is I get a black screen after I login. I am able to access the task manager and launch programs but my desktop remains black for a few minute then it pops to life and the desktop loads. The second problem is that my laptop freezes up usually when multitasking (in a game and voice chatting at the same time), the screen freezes and all sound becomes a gurgled mess. I have to force my computer to turn off I have only had one time when it unfroze. I have ran a disk check, several registry cleaner, and fragments and nothing has fixed these problems. Is there any way to fix this or is there something corrupted and my best bet is to back up everything on my external and format the drive?
