Or at least that's the way it feels. At first I thought it was conflicting AVs as I had installed one I liked and found out that I had Windows Defender on it to, but Windows Defender was disabled and it said I needed to turn it on so I ruled that out.

What happens is when I try to get on before 7 or so, my computer will work for a bit but then freeze. By for a bit I mean long enough to open Google Chrome, type in my e-mail page and then sometimes long enough for that to load but the it freezes. My mouse can still move but I can't open task manager.
And it's not just the internet I will turn off the wireless function (I have also left it on to see if it makes a difference) and open folders, music, or games and they will freeze with the mouse still being able to move.
But at night I can turn it on and it works no problem! My computer isn't even a year old so this is very frustrating. It's an HP 750GB laptop that I use for my pictures.
I have done a system restore on it and it worked fine for almost a week then it started doing this again. I'm trying to see if you leave it on from the previous night if it will work in the day, but I haven't finished that yet.
Oh and it does have Windows 8 on it.

The standard warranty for almost all consumer electronics is either 90 days or 1 year, not 2. HP's is one year and can be checked here

As for possible reasons, it could be overheating during the day and not at night if there's a large change in ambient temperature. Or if you have particular unstable or unclean power it might be better at night due to changes to the system load. or it simply could be that you keep downloading the same spyware or rogue program and it's on some sort of schedule.

It's about...

YOu should still have a manufacturer warranty on it if I am not mistaken. Having two AVs could cause problems, but not like that I do not believe. Your AV hasn't detected any viruses has it? If not it sounds like it make be something corrupted in the Hard Drive (Taking a guess on that).

It's about guaranteed they'll ask you to do a system restore first, and you confirmed that worked, so id lean toward it being something you've done or scheduled maintenance, not the hardware.

Suspected problem: thermal expansion/contraction issue caused chip leg to detach from its solder pad

Diagnosis:
start your computer in the morning, heat the computer memory and mother board with a hair dryer. I guess you could also just boot up into the BIOS for a few mins until your system comes up to operating thermal levels, then power cycle your machine and see if you problem still occurs.

Fix: depends on the component with the problem. memory can be replaced but the problem could be anywhere with the description given
I have see and debugged problems like this: system is cold in the morning, leg of a memory chip contracts away from its solder pad, the system heats up and the leg expands and re established pad contact. problem is that will also change the memory address if the leg controls a memory address line, results in a crash of the system that may not be reproduced if the system is warm. (you can use a can of coolent or heat gun to illustrate and Isolate the failing component)

note: the push to use lead free solder resulted in a lot of failures like this a few years back. the lead free solder was more brittle and would detach from the pad after a bunch of power cycles of machines (heat/cold cycles)
