Several problems with my G74SX. (Not shutting down, random colors, freezing)

I have had my G74SX since about August of last year, and as much as I love this computer, it has had several problems since I bought it. Before this I owned a G51VX-R05 and never had any major problems like this before. So here is a short summary of the problems I have:



1) This one recently concerned me, which made me come post this. Sometimes when I shut down the computer, it never shuts down. It stays on the blue Windows 7 "shutting down..." screen and it never changes. I left once to go to the store and returned 30 minutes later, and it was still shutting down. So I have resorted to just setting it to shut down, waiting a minute or two, and then holding the power button to get it to turn off. Today I came to my computer, and it says Windows could not start, and it ran some kind of startup repair tool to fix it, and luckily it worked. This problem has been going on ever since November or so.

2) It freezes a LOT, and mostly during really simple tasks (never really during games or anything more intensive). Most of the time, I am just browsing on Firefox, nothing demanding at all and nothing demanding running in the background. Most of the time the computer completely locks up, CTRL+ALT+DEL doesn't work, letting it sit there doesn't work, it just stays frozen. So I have to again, force shut down by holding the power button. This has been going on basically since I got it, about 2 weeks in I started noticing it. This happens approximately 1-2 times a week, one of those times are when I cannot recover it.

3) Whenever I turn my computer on from hibernate, usually the entire screen flashes one solid shade of color (75% of the time its red, the other 25% is yellow) for about 1-2 seconds before showing the user login screen. I am not sure if this is a problem, but it definitely doesn't seem normal at all.

4) Whenever I use a certain DVD burning software, when it is at then of the process, and the process says its "finalizing", my computer gets a blue screen of death just as the DVD pops out, every single time. But the DVD turns out fine. So once again, I have to do a force shut down. When I use another program to burn the DVD (less preferable because of less features), it does not give me the blue screen. I noticed this immediately when I bought it.



I love this computer to death, and I have been taking great care of it, but these little problems have been really concerning me. Especially since the previous ASUS laptop I owned was a display model which worked flawlessly for years, and this one had several problems right out of the box. Does anyone know what could be causing any of these, and how I can fix them?

 

What are you specs with your G74SX? Is it modded/upgraded? What hard drives are installed in your system?

Where did you purchase your laptop from? Store or reseller?

The BSODs could have been resolved if you had downloaded and used this tool: WhoCrashed 3.03 - Download.com
Use that tool, it should give you an idea of what caused the BSOD.

If you don't know where the minidump files are located and nothing is coming up, you could try the following:

Click on the Start orb at the lower left corner.

Right-click Computer, select Properties.

Click Advanced System Settings on the left pane.

Click the Settings...button under Startup and Recovery

Look down near the bottom, you should see "Write debugging information" and under that a drop down menu. Select Small memory dump (256 KB) and then click OK.

Now it should be able to create "readable" minidump files.

 

The specs are from the Best Buy model, which is where I purchased it at. The hard drives are one 500gb, and two 250gb hard drives (1tb total). No mods or anything.

I actually had a major crash recently, in which my computer would not boot at all. I had to use the recovery disc to correct this. After working on it for some time and running some scans, I am almost positive it was due to a trojan and launcher that Malwarebytes detected.
