Hello everyone

I have an HP Pavilion dv2621la with windows 7 running on it, and the screen goes black after a while of using it. It's not always the same time, sometimes it runs well for an hour before the screen goes black and sometimes it runs for 10 minutes. After I suspend it with the power button and wake it up again, the screen comes back to normal.
I've already tried reinstalling the graphics driver but it hasn't changed anything.
Anyone has another idea about what could it be?

Thanks in advance, and sorry for my english, it's not my mother language
