Computer Sleep option gone

I have had to do a complete reset of my computer recently and ever since I did that I have not had the option of putting my computer to sleep even after checking all my drivers to see if they are up to date. I am also having a problem where when I turn on my computer It will stay a black screen even though all signs point to it working just nothing shows on the screen. After a complete shutdown by holding the power button and turning it back on it works but doesn't let me get into BIOS. This problem has been a big annoyance and it would be much appreciated if you could help me.

Try pressing the Delete key on startup to get into bios.

What I have done in the past to get boot options to appear is to restart & press the power button to shut my computer off & then push it again to restart it.

Doing this 3 or 4 times causes the boot menu to appear because it did not shut down properly.

I have noticed no ill effects from doing this.

Since I installed Macrium Reflect, I added boot options at startup:



This comes in handy.

Macrium Reflect FREE Edition - Information and download

That's all I know to suggest right now.
Maybe someone else here will have better ideas.
