Windows 7: Acer Veriton z290g making a high pitched whistle

Acer Veriton z290g making a high pitched whistle

When I put my computer to sleep, it stops, and it starts as soon as I turn my computer on. Changes frequency right before the login screen comes on, and then it stays the same after that. My PC also takes a while to start up now. I have to shut it off and back on maybe 2-3 times before it'll boot up. Just a few minutes ago, Windows sent me to this uh... resume(?) screen that I've NEVER seen before.

Are these 2 things completely unrelated? Could I possibly have a virus that's causing this?

edit: it also changes frequency during windows' admin program run notification

My computer's having more problems starting up. It goes on and off, and my mouse flickers with it. The whistling constantly changes frequency during this time.

sorry for double posting/bumping, but I really need help with this. it's an all-in-one computer btw.
