I recently built a computer with these specs: Asus Motherboard, Intel i3 3.3 GHz dual processor, 8 GB of RAM. I installed 12.04 on a brand new hard drive. I partitioned the hard drive between root, home and swap like I have often read how to do.

I cannot get this machine to properly shutdown. I have to hold the power button down now. Although, for the first few days it properly shutdown.

I also cannot get the system to hibernate or suspend properly. I have read tons on this and watched many YouTube tutorials on how to fix both, but the computer never wakes up after suspend or hibernate. It just stays on a black screen.

Can anyone help? I love 12.04 so far, but these setbacks are making me worried about stability and power management issues. Also, I wonder if it's really bad for the hard drive to force the CPU to shutdown.
