Today I was working on my Macbook pro 15" (Intel Core i7, 2011 model)
and suddenly the whole thing froze, no mouse movement, no nothing.
I rebooted, after pressing the power button for 10 seconds.
On boot, when the blue screen shows up it doesn't turn into that darker shade before going to the log in screen,
I had to press the power button again for 10 seconds and try to boot again.
It worked, but suddenly a while after login it froze again.
I thought it was because of Chrome, found some topics about it, so tried to back up my bookmarks and it froze again.
After installing Firefox and deleting Chrome it all seemed fine.
Now, because I was considering to do a clean install anyway and wasn't sure if I'd better run the time machine and return the system to when I bought the computer, the system froze again on entering Time Machine... great...
I tried another time, maybe it would work, but no... nothing but a freeze...
I checked for the necessary info to do a clean install and set the whole system back to factory settings.
Starting from scratch seemed not too bad, just for my personal feeling to start off with a clean running machine.
I inserted the DVD, chose for the restart option.
On reboot the DVD starts spinning (DVD and drive are in good shape, double checked this) and then again when the blue screen appears after the grey screen with logo, the system stops and I can't install the DVD which came with my macbook pro.
I tried several times but no succes, even installing the OS normally without erasing the disk, makes the system stop when the blue screen appears after the logo.
My system runs, but I am not feeling comfortable with it and just want to have a clean install now and get working again.
I hope someone can come up with a smooth sollution, this is the worse situation I ever had with my mac since I bought it, I'm surprised things could get this messy.
Thanks in advance!
