My problem is fairly simple, just my computer going into sleep mode around every three minutes or so if I don't use my mouse or keyboard. This usually isn't that big of a problem, but when I'm reading a long body of text and not using my mouse or keyboard, it can irk me a little when the screen goes black. I've tried nearly every option on my Windows 7 control panel, but to no avail. Even with my power plan settings directing my computer to never go to sleep and to never turn off its display, it still does the same thing. Strangely enough, this problem only arose after I got a new Logitech M510 wireless mouse. So, people of Tom's Hardware, what do I do to fix this?
