Why does my MacBook Pro turn off several times a day?
my MacBook Pro goes black several times a day. I'm not able to do anything with it then but dead boot it. I do run programs on it that run 24/7 and have to reopen every single one every time i have to reboot. The screen goes black at different times, and lately even sometimes when i'm not switching between windows or open a new window up. PLease help i love my mac but this is getting really frustrating

ok. Worked at comp most off the day. Reset SMC and PRAM as per examples. After resetting SMC a bit more trouble getting the computer to run did not want to kick back into starting apple icon. Seems fixed now. Then promptly another screen crash. Screen black. Used flashlight, but nothing was visible. The only thing not done is hook the computer up to external monitor. A copy of the trouble report sent to Apple as follows:
I will have to sent it in parts the comment is too long otherwise
