I've got a dell inspiron 5100 notebook, and its worked perfectly for me except for the past about month. All of a sudden when I would try to turn it on it would beep 4 times and the screen wouldnt come on. The fans would come on and so would a few lights (capslock and scrolllock). I would hard shut down my computer (just holding the power button till it turned off) and then try again. After the third or fourth try, it would start up right and run normal. Its been getting harder and harder to turn on recently. I was just curious if anyone had any ideas of what might be causing this, or any possible solutions.
