Newby: please help?
My HP pavillion xh365 laptop goes black after running for a few minutes to several hours. The only way to recover the screen is to reboot. When the screen goes black, I can hear some changes in the pc. Normally, the sounds I hear are just the hardrive and the fans, but when the screen goes black, I hear some changes in the pitch of one of the sounds. I have the same problem whether the laptop is running on the built in display or is conneted to an external display. Both screens go black at the same time. What do you suppose the problem is.
Thanks so much, Jerry.
