Fedora 17, not starting up or hangs
I have installed Fedora 17, x86_64, on Dell E6510.
The problem is sometimes when I power on the laptop on fedora, it does not start sometimes. Or, when the system is left idle for a while, it hangs and I should restart.
Is there a problem with my installation?
Could it be the problem of "ram" or sth else?
Is it possible to solve it by updating to Fedora 18?
