I built a computer almost 3 years ago, and I am having a problem now.
First the monitor, keyboard, and mouse shut off, but the computer stayed on and the lightning bolt LED lit up on the case. The only way to shut if off was to hold down the power button. Then I turned it back on. After a few minutes it happened again. I opened the case and cleaned lots of dust out, and then it ran fine for a week.
But today the same thing happened again, so I opened it up and cleaned much more thoroughly, especially the CPU heatsink, which was very dusty upon close inspection.
Well apparently that made it worse because now when I turn it on, after a few seconds it seems to shut off and turn right back on with the lightning bolt LED on the case lit up, and my monitor, keyboard, and mouse stay shut off. My front case fan, bottom case fan, and CPU fan run in this state, but the rear (exhaust) case fan that is behind the CPU is now off. I think this is exactly what was happening a week ago, I just didn't have the case open to watch.
Was dust the problem? Did that have nothing to do with it and this is a component failing?
