Black screen at random
2 identical TOSHIBA laptops.. windows 7.. Both BLACK SCREENED. In basement for over 3 years. Got into 1st one and blanked password and deleted programs, updated, removed pop up ''call me'' problem. Was restarted maybe 30 times. No problem. Got into other one.. did much the same... both worked fine. Today.. NEITHER ONE WILL WORK.. Start up and run with BLACK SCREEN. Cannot get into them. Same problem on same type computers.. Wonder if it is a Toshiba thing or I'm thinking a heat and graphics problem. No luck with hooking to another monitor. No indication of logo and such checking with light on monitor.. ANY HELP APPRECIATED.
