Dell Insperion 1545 laptop screen goes black during operation

I have a Dell Insperion 1545 laptop. I can power up the windows 7 system just fine. After a while I will be typing on it or playing solitair and all of a sudden the screen will go black. Then I click the power button one time and the fan comes back on and it takes me to the login screen. I log on and it takes me back to where I was. It may turn off 2 o3 more times before it stays on a while. Is there a solution for this?

Hello and welcome.

When the screen comes back on, does it have a reddish tint to it?
