Can anyone help with a couple of issues I'm having since installing windows 10? Firstly, my laptop has trouble starting now. It takes about 20 tries before it will actually start. It either goes directly to a black screen and does nothing, or it will start to go through the process but then goes to black screen and stops doing anything. Also, my sleep mode stopped working the night windows 10 was installed, it does the same thing when I try to wake it up.
