Okay, so recently (past 3 weeks) my laptop - g53sx - has started acting weird. Sometimes the screen just gets a random color (so far I've seen orange, white, green, light blue) and nothing works, no ctrl-alt-del or any of those, the only thing I can do is hold the power button until it shuts down. The computer also plays some tone that increases or decreases in frequency every 5 seconds or so.
The crashes have occured when I'm watching YouTube videos, playing games, doing homework and at different times so I can't figure out what is causing them.
I can't remember if I updated something about 3 weeks ago but I'm pretty sure I haven't installed or downloaded a program since like 1.5 months or something.
Also, WhoCrashed can't find any recent crashes. (or am I wrong to call them crashes? freezes?)
