So my screen keeps randomly blacking out on me. It's happened twice while simply using the internet, nothing graphics intensive. The last time I reset it, it lasted maybe half an hour before blacking out on me again.
My indicator lights still say that it's on. If I hard shut it off, it'll power down, but trying to hibernate it or anything else with the power button doesn't work. I even waited seven minutes (approximately how long I took reheating food) for it to go to sleep and nothing.
I'm running windows 7 64bit, Dell inspiron M5030 (it's about five years old), Generic PnP Monitor (1366x768@60Hz), ATI Mobility Radeon HD 4250 (Dell).
Any ideas of what could be wrong?
