I seem to get random crashes.
First the screen will freeze itself for about 2-3 seconds. During this period I can still hear the sound or static at least. Then my computer will just shut itself down instantly, although the power is still on. Sometimes it will then come back on on it's own. Other times I'll have to turn the power off and on for it to come back on. Sometimes that doesn't even work and I have to unplug it entirely.
I've found that if I keep my computer shut off at night, it'll be fine for quite a bit of the next day. But once it does start crashing, the crashes become more and more frequent until I just get fed up, call it a day, and keep it off entirely.
I reformatted my about 2 weeks after it started happening but that didn't help, so it's probably a hardware issue. I'm hoping you guys have a solution, or you can at least identify the piece of hardware causing this so I can replace it.
